+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<http://www.gnu.org/licenses/>.

+This document outlines the steps necessary to use the MuPDF Android SDK in various ways.
+
+<p>
+First, we show you how to embed the SDK in your app. Then, we explain how to
+customize the viewer if you need to change how it looks or behaves. Finally, we
+tell you where to go if you need to do work on the SDK itself.
+
+<p>
+Embedding the viewer in your app provides an activity that you can start to
+view PDF documents from within your app. This should be enough for most use
+cases.
+
+<h2 id="acquire-license">
+Acquire a valid license
+</h2>
+
+<p>
+Before using MuPDF, please make sure that you have a valid license to do so.
+There are two available licenses; make sure you pick the one whose terms you can comply with.
+
+<h3>
+Open Source license
+</h3>
+
+<p>
+If your software is open source, you may use MuPDF under the terms of the
+<a href="https://www.gnu.org/licenses/agpl-3.0.html">GNU Affero General Public License</a>.
+
+<p>
+This means that <i>all of the source code</i> for your <i>complete</i> app must be
+released under a compatible open source license!
+
+<p>
+It also means that you may <i>not</i> use any proprietary closed source libraries or
+components in your app. This includes (but is not limited to)
+	Google Play Services,
+	Google Mobile Services,
+	AdMob by Google,
+	Crashlytics,
+	Answers,
+	etc.
+
+<p>
+Just because a library ships with Android or is made by Google does <i>not</i> make it AGPL compatible!
+
+<p>
+If you cannot or do not want to comply with these restrictions,
+you <i><b>must</b></i> acquire a commercial license instead.
+
+<h3>
+Commercial license
+</h3>
+
+<p>
+If your software is not open source, Artifex Software can sell you a license to use MuPDF in closed source software.
+Go and fill out the <a href="https://www.artifex.com/contact-us/">product inquiry form</a>
+for commercial licensing terms and pricing.
+
+<h2 id="setup-build">
+Add the MuPDF SDK to your project
+</h2>
+
+<p>
+The MuPDF library uses the Gradle build system.
+In order to include MuPDF in your app, you also need to use Gradle.
+The Eclipse and Ant build systems are not supported.
+
+<p>
+The MuPDF library needs Android version 4.1 or newer.
+Make sure that the minSdkVersion in your app's build.gradle is at least 16.
+
+<pre>
+android {
+	defaultConfig {
+		<b>minSdkVersion 16</b>
+		...
+	}
+	...
+}
+</pre>
+
+<p>
+The MuPDF library can be retrieved as a pre-built artifact from our Maven repository.
+Add the maven repository to your project. In your project's top build.gradle, add the bolded line to
+to the repositories section:
+
+<pre>
+allprojects {
+	repositories {
+		jcenter()
+		<b>maven { url 'http://maven.ghostscript.com' }</b>
+		...
+	}
+}
+</pre>
+
+<p>
+Then add the MuPDF viewer library to your app's dependencies.
+In your app's build.gradle, add the bolded line to the dependencies section:
+
+<pre>
+dependencies {
+	<b>api 'com.artifex.mupdf:viewer:1.15.+'</b>
+	...
+}
+</pre>
+
+<h2 id="use-activity">
+Invoke the document viewer activity
+</h2>
+
+<p>
+Once this has been done, you have access to the MuPDF viewer activity.
+You can now open a document viewing activity by launching an intent,
+passing the URI of the document you wish to view.
+
+<pre>
+import com.artifex.mupdf.viewer.DocumentActivity;
+
+public void startMuPDFActivity(Uri documentUri) {
+	Intent intent = new Intent(this, DocumentActivity.class);
+	intent.setAction(Intent.ACTION_VIEW);
+	intent.setData(documentUri);
+	startActivity(intent);
+}
+</pre>
+
+<p>
+The activity supports viewing both file and content scheme URIs.
+
+<p>
+For example, to open the PDF file in ~/Download/example.pdf:
+
+<pre>
+public void startMuPDFActivityWithExampleFile() {
+	File dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
+	File file = new File(dir, "example.pdf");
+	Uri uri = Uri.fromFile(file);
+	startMuPDFActivity(uri);
+}
+</pre>
+
+<h2>
+How to customize the viewer
+</h2>
+
+<p>
+If you've already tried embedding the viewer in your app, but are unhappy with some
+aspect of the look or behavior and want to modify it in some way, this document should
+point you in the right direction.
+
+<h3>
+Decide which viewer to base your customizations on
+</h3>
+
+<p>
+In order to customize the viewer UI, you will need to modify the existing android viewer activity.
+There are two separate code bases you can start with:
+
+<dl>
+<dt>mupdf-android-viewer:
+<dd>The main viewer app. This code is difficult to work with, but has the most
+features and pre-renders neighboring pages into a page cache for faster page
+turning performance.
+<dt>mupdf-android-viewer-mini:
+<dd>This is a minimalist viewer which has fewer features but is designed to be
+easy to understand and modify. It does not (currently) have high-resolution
+zooming, and it does not use the swipe gesture to flip pages (it requires the
+user to tap on the side of the screen to flip pages).
+</dl>
+
+<p>
+If all you want to do is brand the UI with your own colors and icons, you are
+welcome to use whichever code base you prefer. However, if you want to do
+extensive modifications, we suggest you base your code on the mini viewer.
+
+<h3>
+Check out the chosen project
+</h3>
+
+<p>
+When you have decided which project to base your modifications on, you should check out
+the corresponding git repository:
+
+<pre>
+$ git clone git://git.ghostscript.com/mupdf-android-viewer.git
+$ git clone git://git.ghostscript.com/mupdf-android-viewer-mini.git
+</pre>
+
+<p>
+Inside the checked out project you will find two modules: app and lib.
+The app module is a file chooser activity that lets the user open files from the external storage.
+The lib module is the viewer activity, which provides the "com.artifex.mupdf:viewer"
+package that you're already using.
+
+<p>
+The lib module is the one you want; ignore everything else in this project.
+
+<h3>
+Copy the viewer library module into your project
+</h3>
+
+<p>
+Copy the 'lib' directory to your project, renaming it to something appropriate.
+The following instructions assume you called the directory 'mupdf-lib'.
+Don't forget to include the module in the settings.gradle file:
+
+<pre>
+include ':app'
+<b>include ':mupdf-lib'</b>
+...
+</pre>
+
+<p>
+You'll also want to change your app's dependencies to now depend on your local
+copy rather than the official mupdf viewer package. In your app build.gradle:
+
+<pre>
+dependencies {
+	<strike>api 'com.artifex.mupdf:viewer:1.15.+'</strike>
+	<b>api project(':mupdf-lib')</b>
+	...
+}
+</pre>
+
+<p>
+The lib module depends on the JNI library "com.artifex.mupdf:fitz", so do
+<i>not</i> remove the maven repository from your top build.gradle.
+
+<h3>
+Edit the viewer activity
+</h3>
+
+<p>
+If all has gone well, you can now build your project with the local viewer library,
+and access the mupdf viewer activity just as you used to.
+
+<p>
+You're now free to customize the resources in mupdf-lib/src/main/res and behavior in
+mupdf-lib/src/main/java as you desire.
+
+<h2>
+Working on the MuPDF SDK
+</h2>
+
+<p>
+If you want to work on the SDK itself, rather than just use it, you will need
+to check out the following git repositories.
+
+<dl>
+<dt>mupdf.git
+<dd>This repository contains the low-level "fitz" C library and the JNI bindings.
+<dt>mupdf-android-fitz.git
+<dd>This repository contains an Android project to build the C library and JNI bindings.
+It uses mupdf.git as a git submodule.
+<dt>mupdf-android-viewer.git
+<dd>This repository contains the Android viewer library and app.
+It uses mupdf-android-fitz.git as either a Maven artifact or git submodule.
+<dt>mupdf-android-viewer-mini.git
+<dd>This repository contains the minimalist Android viewer library and app.
+It uses mupdf-android-fitz.git as either a Maven artifact or git submodule.
+<dt>mupdf-android-viewer-old.git
+<dd>This repository contains the old Android viewer. It has its own JNI
+bindings and uses mupdf.git as a submodule directly. It is only listed here for
+completeness sake, and is not part of the SDK.
+</dl>
+
+<p>
+Since these repositories are set up as git submodules, if you're a Git expert,
+you can clone one of the viewer repositories recursively and get all of them at
+once. However, working with git submodules can be fraught with danger, so it
+may be easier to check them out individually.
+
+<p>
+If you only want to work with one of the viewer repositories, you can use the
+Maven artifact for the JNI bindings library and not worry about the mupdf.git
+and mupdf-android-fitz.git repositories.
+
+<p>
+Good luck!

+<title>API Changes</title>
+<link rel="stylesheet" href="../style.css" type="text/css">
+</head>

+
+<header>
+<h1>Changes in the public API</h1>
+</header>
+
+<article>
+
+<h2>Why does the API change?</h2>
+
+<p>
+From time to time, during development, it becomes clear that the
+public API needs to change; either because the existing API has
+flaws in it, or to accommodate new functionality. Such changes
+are not undertaken lightly, and they are kept as minimal as
+possible.
+
+<p>
+The alternative would be to freeze the API and to introduce more
+and more compatibility veneers, ultimately leading to a bloated
+API and additional complexity. We have done this in the past, and
+will do it again in future if circumstances demand it, but we
+consider small changes in the API to be a price worth paying for
+clarity and simplicity.
+
+<p>
+To minimise the impact of such changes, we undertake to list the
+API changes between different versions of the library here, to
+make it as simple as possible for integrators to make the small
+changes that may be require to update between versions.
+
+<p>
+Note, that we only list changes in existing APIs here, not additions
+to the API.
+
+<h2>Changes from v1.16</h2>
+
+<p>
+The accessors for reading and creating QuadPoints, InkList and Vertices data
+for Highlight, Underline, StrikeOut, Squiggle, Ink, Polygon, and PolyLine
+annotation types have been simplified. They now take and return fz_quad and
+fz_point structs instead of float arrays. We have also added functions to
+construct the datastructures one piece at a time, removing the need to allocate
+a temporary array to pass.
+
+<h2>Changes from v1.15</h2>
+
+<p>
+There has been a major overhaul of the color management architecture. Unless
+you're implementing custom devices or interpreters, this should only have a
+minor impact.
+
+<ul>
+<li>Argument order when passing color and colorspace to functions regularized:
+	sourceColorspace, sourceColorArray,
+	destinationColorspace, destinationColorArray,
+	proofColorspace,
+	colorParams.
+<li>Pass fz_color_params argument by value.
+<li>Changed fz_default_parameters from a function to a global constant.
+<li>Replaced fz_set_icc_engine with fz_enable_icc and fz_disable_icc to toggle color management at runtime.
+<li>Replaced pixmap color converter struct with a single fz_convert_pixmap function call.
+<li>Replaced fz_cal_colorspace struct with constructor to create an ICC-backed calibrated colorspace directly.
+<li><b>Passing NULL is not a shortcut for DeviceGray any more!</b>
+<li>Added public definitions for Indexed and Separation colorspaces.
+<li>Changed colorspace constructors.
+</ul>
+
+<p>
+The fz_set_stdout and fz_set_stderr functions have been removed.
+If you were using these to capture warning and error messages,
+use the new user callbacks for warning and error logging instead:
+fz_set_warning_callback and fz_set_error_callback.
+
+<p>
+The structured text html and xhtml output formats take an additional argument:
+the page number. This number is used to create an id attribute for each page to
+use as a hyperlink target.
+
+<h2>Changes from v1.14 to v1.15</h2>
+
+<dl>
+
+<dt>PDF Portfolios
+<dd>This functionality has been removed. We do
+not believe anyone was using this. If you were, please contact
+us for assistance. This functionality can be achieved using
+"mutool run" and docs/examples/pdf-portfolio.js.
+
+<dt>FZ_ERROR_TRYLATER
+<dd>This functionality has been removed. We do
+not believe anyone was using this. If you were, please contact
+us for assistance.
+
+<dt>Annotations/Forms
+<dd>We are undertaking a significant rework of this functionality
+at the moment. We do not believe anyone is using this at the moment,
+and would therefore encourage anyone who is to contact us for help
+in upgrading.
+
+<dt>Various functions involving fz_colorspace have lost consts.
+<dd>fz_colorspaces are immutable once created, other than changes
+due to reference counting. Passing a const fz_colorspace to a function
+that might keep a reference to it either has to take a non const
+fz_colorspace pointer, or take a const one, and 'break' the const.
+Having some functions take const fz_colorspace and some not is
+confusing, so therefore, for simplicity, all fz_colorspaces are now
+passed as non const.
+This should not affect any user code.
+
+<dt>fz_process_shade()
+<dd>This now takes an extra 'scissor' argument.
+To upgrade old code, if you don't have an appropriate scissor rect available,
+it is safe (but unwise) to pass fz_infinite_rect.
+
+<dt>fz_tint_pixmap()
+<dd>Rather than taking r, g and b, values to tint with, the
+function now takes 8 bit hex rgb values for black and white,
+enabling greater control, allowing "low contrast" and "night
+view" effects.
+
+<dt>pdf_add_image()
+<dd>This no longer requires a mask flag. The image already knows if it is a mask.
+
+<dt>pdf_processor.op_BI()
+<dd>The op_BI callback is now passed an additional colorspace resource name.

+<h1>MuPDF Core API</h1>
+</header>
+
+<article>
+
+<p>
+Almost all functions in the MuPDF library take a fz_context structure as their
+first argument. The context is used for many things; primarily it holds the
+exception stack for our setjmp based exception handling. It also holds various
+caches and auxiliary contexts for font rendering and color management.
+
+<h2>The Fitz Context</h2>
+
+<p>
+<i>If you wonder where the prefix "fz" and name Fitz come from, MuPDF originally
+started out as a prototype of a new rendering library architecture for Ghostscript.
+It was to be the "bastard son" of libart and Ghostscript. History turned out
+differently, and the project mutated into a standalone PDF renderer now called MuPDF.
+The "fz" prefix for the graphics library and core modules remains to this day.
+</i>
+
+
+<p>
+Here is the code to create a Fitz context. The first two arguments are used if
+you need to use a custom memory allocator, and the third argument is a hint to
+much memory the various caches should be allowed to grow. The limit is only a
+soft limit. We may exceed it, but will start clearing out stale data to try to
+stay below the limit when possible. Setting it to a lower value will prevent
+the caches from growing out of hand if you are tight on memory.
+
+<pre>
+#include &lt;mupdf/fitz.h&gt;
+
+main()
+{
+	fz_context *ctx;
+
+	ctx = fz_new_context(NULL, NULL, FZ_STORE_UNLIMITED);
+	if (!ctx)
+		die("Failed to create a new Fitz context!");
+
+	<i>... do stuff ...</i>
+
+	fz_drop_context(ctx);
+}
+</pre>
+
+<h2>Error Handling</h2>
+
+<p>
+MuPDF uses a setjmp based exception handling system. This is encapsulated
+by the use of three macros: fz_try, fz_always, and fz_catch.
+When an error is raised by fz_throw, or re-raised fz_rethrow, execution
+will jump to the enclosing always/catch block.
+
+<p>
+All functions you call should be guarded by a fz_try block to catch the
+errors, or the program will call abort() on errors. You don't want that.
+
+<p>
+The fz_always block is optional. It is typically used to free memory
+or release resources unconditionally, in both the case when the execution
+of the try block succeeds, and when an error occurs.
+
+<pre>
+fz_try(ctx) {
+	// Do stuff that may throw an exception.
+}
+fz_always(ctx) {
+	// This (optional) block is always executed.
+}
+fz_catch(ctx) {
+	// This block is only executed when recovering from an exception.
+}
+</pre>
+
+<p>
+Since the fz_try macro is based on setjmp, the same conditions that apply
+to local variables in the presence of setjmp apply. Any locals written
+to inside the try block may be restored to their pre-try state when an
+error occurs. We provide a fz_var() macro to guard against this.
+
+<p>
+In the following example, if we don't guard 'buf' with fz_var, then
+when an error occurs the 'buf' local variable might have be reset to
+its pre-try value (NULL) and we would leak the memory.
+
+<pre>
+char *buf = NULL;
+fz_var(buf);
+fz_try(ctx) {
+	buf = fz_malloc(ctx, 100);
+	// Do stuff with buf that may throw an exception.
+}
+fz_always(ctx) {
+	fz_free(ctx, buf);
+}
+fz_catch(ctx) {
+	fz_rethrow(ctx);
+}
+</pre>
+
+<p>
+Carefully note that you should <i><b>NEVER</b></i> return from within a fz_try or fz_always block!
+Doing so will unbalance the exception stack, and things will go catastrophically wrong.
+Instead, it is possible to break out of the fz_try and fz_always block by using a break
+statement if you want to exit the block early without throwing an exception.
+
+<p>
+Throwing a new exception can be done with fz_throw. Passing an exception along after having
+cleaned up in the fz_catch block can be done with fz_rethrow. fz_throw takes a printf-like
+formatting string.
+
+<pre>
+enum {
+	FZ_ERROR_MEMORY, // when malloc fails
+	FZ_ERROR_SYNTAX, // recoverable syntax errors
+	FZ_ERROR_GENERIC, // all other errors
+};
+void fz_throw(fz_context *ctx, int error_code, const char *fmt, ...);
+void fz_rethrow(fz_context *ctx);
+</pre>
+
+<h2>Memory Allocation</h2>
+
+<p>
+You should not need to do raw memory allocation using the Fitz context, but if you do,
+here are the functions you need. These work just like the regular C functions, but take
+a Fitz context and throw an exception if the allocation fails. They will NOT return NULL;
+either they will succeed or they will throw an exception.
+
+<pre>
+void *fz_malloc(fz_context *ctx, size_t size);
+void *fz_realloc(fz_context *ctx, void *old, size_t size);
+void *fz_calloc(fz_context *ctx, size_t count, size_t size);
+void fz_free(fz_context *ctx, void *ptr);
+</pre>
+
+<p>
+There are also some macros that allocate structures and arrays, together with a type cast
+to catch typing errors.
+
+<pre>
+T *fz_malloc_struct(fz_context *ctx, T); // Allocate and zero the memory.
+T *fz_malloc_array(fz_context *ctx, size_t count, T); // Allocate <i>uninitialized</i> memory!
+T *fz_realloc_array(fz_context *ctx, T *old, size_t count, T);
+</pre>
+
+<p>
+In the rare case that you need an allocation that returns NULL on failure,
+there are variants for that too: fz_malloc_no_throw, etc.
+
+<h2>Pool Allocator</h2>
+
+<p>
+The pool allocator is used for allocating many small objects that live and die together.
+All objects allocated from the pool will be freed when the pool is freed.
+
+<pre>
+typedef struct { <i>opaque</i> } fz_pool;
+
+fz_pool *fz_new_pool(fz_context *ctx);
+void *fz_pool_alloc(fz_context *ctx, fz_pool *pool, size_t size);
+char *fz_pool_strdup(fz_context *ctx, fz_pool *pool, const char *s);
+void fz_drop_pool(fz_context *ctx, fz_pool *pool);
+</pre>
+
+<h2>Reference Counting</h2>
+
+<p>
+Most objects in MuPDF use reference counting to keep track of when they are no longer
+used and can be freed. We use the verbs "keep" and "drop" to increment and decrement
+the reference count. For simplicity, we also use the word "drop" for non-reference
+counted objects (so that in case we change our minds and decide to add reference counting
+to an object, the code that uses it need not change).
+
+<h2>Hash Table</h2>
+
+<p>
+We have a generic hash table structure with fixed length keys.
+
+<p>
+The keys and values are <i>not</i> reference counted by the hash table.
+Callers are responsible for manually taking care of reference counting
+when inserting and removing values from the table, should that be
+desired.
+
+<pre>
+typedef struct { <i>opaque</i> } fz_hash_table;
+</pre>
+
+<dl>
+<dt>fz_hash_table *fz_new_hash_table(fz_context *ctx,
+	int initial_size,
+	int key_length,
+	int lock,
+	void (*drop_value)(fz_context *ctx, void *value));
+<dd>
+The lock parameter should be zero, any other value will result in unpredictable behavior.
+The drop_value callback function to the constructor is only used to
+release values when the hash table is destroyed.
+
+<dt>void fz_drop_hash_table(fz_context *ctx, fz_hash_table *table);
+<dd>
+Free the hash table and call the drop_value function on all the values in the table.
+
+<dt>void *fz_hash_find(fz_context *ctx, fz_hash_table *table, const void *key);
+<dd>
+Find the value associated with the key. Returns NULL if not found.
+
+<dt>void *fz_hash_insert(fz_context *ctx, fz_hash_table *table, const void *key, void *value);
+<dd>Insert the value into the hash table.
+Inserting a duplicate entry will NOT overwrite the old value, it will return the old value instead.
+Return NULL if the value was inserted for the first time.
+Does <i>not</i> reference count the value!
+
+<dt>void fz_hash_remove(fz_context *ctx, fz_hash_table *table, const void *key);
+<dd>
+Remove the associated value from the hash table. This will <i>not</i> reference count the value!
+
+<dt>void fz_hash_for_each(fz_context *ctx,
+	fz_hash_table *table,
+	void *state,
+	void (*callback)(fz_context *ctx, void *state, void *key, int key_length, void *value);
+<dd>
+Iterate and call a function for each key-value pair in the table.
+</dl>
+
+<h2>Binary Tree</h2>
+
+<p>
+The fz_tree structure is a self-balancing binary tree that maps text strings to values.
+
+<dl>
+<dt>typedef struct { <i>opaque</i> } fz_tree;
+<dt>void *fz_tree_lookup(fz_context *ctx, fz_tree *node, const char *key);
+<dd>Look up an entry in the tree. Returns NULL if not found.
+<dt>fz_tree *fz_tree_insert(fz_context *ctx, fz_tree *root, const char *key, void *value);
+<dd>Insert a new entry into the tree. Do not insert duplicate entries. Returns the new root object.
+<dt>void fz_drop_tree(fz_context *ctx, fz_tree *node, void (*dropfunc)(fz_context *ctx, void *value));
+<dd>Free the tree and all the values in it.
+</dl>
+
+<p>
+There is no constructor for this structure, since there is no containing root structure.
+Instead, the insert function returns the new root node.
+Use NULL for the initial empty tree.
+
+<pre>
+fz_tree *tree = NULL;
+tree = fz_tree_insert(ctx, tree, "A", my_a_obj);
+tree = fz_tree_insert(ctx, tree, "B", my_b_obj);
+tree = fz_tree_insert(ctx, tree, "C", my_c_obj);
+assert(fz_tree_lookup(ctx, tree, "B") == my_b_obj);
+</pre>
+
+<h2>XML Parser</h2>
+
+<p>
+We have a rudimentary XML parser that handles well formed XML. It does not do any namespace processing,
+and it does not validate the XML syntax.
+
+<p>
+The parser supports UTF-8, UTF-16, iso-8859-1, iso-8859-7, koi8, windows-1250, windows-1251,
+and windows-1252 encoded input.
+
+<p>
+If preserve_white is false, we will discard all whitespace-only text elements.
+This is useful for parsing non-text documents such as XPS and SVG.
+Preserving whitespace is useful for parsing XHTML.
+
+<pre>
+typedef struct { <i>opaque</i> } fz_xml_doc;
+typedef struct { <i>opaque</i> } fz_xml;
+
+fz_xml_doc *fz_parse_xml(fz_context *ctx, fz_buffer *buf, int preserve_white);
+void fz_drop_xml(fz_context *ctx, fz_xml_doc *xml);
+fz_xml *fz_xml_root(fz_xml_doc *xml);
+
+fz_xml *fz_xml_prev(fz_xml *item);
+fz_xml *fz_xml_next(fz_xml *item);
+fz_xml *fz_xml_up(fz_xml *item);
+fz_xml *fz_xml_down(fz_xml *item);
+</pre>
+
+<dl>
+<dt>int fz_xml_is_tag(fz_xml *item, const char *name);
+<dd>Returns true if the element is a tag with the given name.
+<dt>char *fz_xml_tag(fz_xml *item);
+<dd>Returns the tag name if the element is a tag, otherwise NULL.
+<dt>char *fz_xml_att(fz_xml *item, const char *att);
+<dd>Returns the value of the tag element's attribute, or NULL if not a tag or missing.
+<dt>char *fz_xml_text(fz_xml *item);
+<dd>Returns the UTF-8 text of the text element, or NULL if not a text element.
+<dt>fz_xml *fz_xml_find(fz_xml *item, const char *tag);
+<dd>Find the next element with the given tag name. Returns the element itself if it matches, or the first sibling if it doesn't. Returns NULL if there is no sibling with that tag name.
+<dt>fz_xml *fz_xml_find_next(fz_xml *item, const char *tag);
+<dd>Find the next sibling element with the given tag name, or NULL if none.
+<dt>fz_xml *fz_xml_find_down(fz_xml *item, const char *tag);
+<dd>Find the first child element with the given tag name, or NULL if none.
+</dl>
+
+<h2>String Functions</h2>
+
+<p>
+All text strings in MuPDF use the UTF-8 encoding. The following functions encode and decode UTF-8 characters,
+and return the number of bytes used by the UTF-8 character (at most FZ_UTFMAX).
+
+<pre>
+enum { FZ_UTFMAX=4 };
+int fz_chartorune(int *rune, const char *str);
+int fz_runetochar(char *str, int rune);
+</pre>
+
+<p>
+Since many of the C string functions are locale dependent, we also provide
+our own locale independent versions of these functions. We also have a couple
+of semi-standard functions like strsep and strlcpy that we can't rely on
+the system providing. These should be pretty self explanatory:
+
+<pre>
+char *fz_strdup(fz_context *ctx, const char *s);
+float fz_strtof(const char *s, char **es);
+char *fz_strsep(char **stringp, const char *delim);
+size_t fz_strlcpy(char *dst, const char *src, size_t n);
+size_t fz_strlcat(char *dst, const char *src, size_t n);
+void *fz_memmem(const void *haystack, size_t haystacklen, const void *needle, size_t needlelen);
+int fz_strcasecmp(const char *a, const char *b);
+</pre>
+
+<p>
+There are also a couple of functions to process filenames and URLs:
+
+<dl>
+<dt>char *fz_cleanname(char *path);
+<dd>
+Rewrite path in-place to the shortest string that names the same path.
+Eliminates multiple and trailing slashes, and interprets "." and "..".
+
+<dt>void fz_dirname(char *dir, const char *path, size_t dir_size);
+<dd>Extract the directory component from a path.
+
+<dt>char *fz_urldecode(char *url);
+<dd>Decode URL escapes in-place.
+</dl>
+
+<h2>String formatting</h2>
+
+<p>
+Our printf family handles the common printf formatting characters, with a few minor differences.
+We also support several non-standard formatting characters.
+The same printf syntax is used in the printf functions in the I/O module as well.
+
+<pre>
+size_t fz_vsnprintf(char *buffer, size_t space, const char *fmt, va_list args);
+size_t fz_snprintf(char *buffer, size_t space, const char *fmt, ...);
+char *fz_asprintf(fz_context *ctx, const char *fmt, ...);
+</pre>
+
+<dl>
+<dt>%%, %c, %e, %f, %p, %x, %d, %u, %s
+<dd>These behave as usual, but only take padding (+,0,space), width, and precision arguments.
+<dt>%g float
+<dd>Prints the float in the shortest possible format that won't lose precision,
+except NaN to 0, +Inf to FLT_MAX, -Inf to -FLT_MAX.
+<dt>%M fz_matrix*
+<dd>Prints all 6 coefficients in the matrix as %g separated by spaces.
+<dt>%R fz_rect*
+<dd>Prints all x0, y0, x1, y1 in the rectangle as %g separated by spaces.
+<dt>%P fz_point*
+<dd>Prints x, y in the point as %g separated by spaces.
+<dt>%C int
+<dd>Formats character as UTF-8. Useful to print unicode text.
+<dt>%q char*
+<dd>Formats string using double quotes and C escapes.
+<dt>%( char*
+<dd>Formats string using parenthesis quotes and postscript escapes.
+<dt>%n char*
+<dd>Formats string using prefix / and PDF name hex-escapes.
+</dl>
+
+<h2>Math Functions</h2>
+
+<p>
+We obviously need to deal with lots of points, rectangles, and transformations in MuPDF.
+
+<p>
+Points are fairly self evident. The fz_make_point utility function is for use with
+Visual Studio that doesn't yet support the C99 struct initializer syntax.
+
+<pre>
+typedef struct {
+	float x, y;
+} fz_point;
+
+fz_point fz_make_point(float x, float y);
+</pre>
+
+<p>
+Rectangles are represented by two pairs of coordinates.
+The x0, y0 pair have the smallest values, and in the normal
+coordinate space used by MuPDF that is the upper left corner.
+The x1, y1 pair have the largest values, typically the lower right corner.
+
+<p>
+In order to represent an infinite unbounded area, we use an x0 that
+is larger than the x1.
+
+<pre>
+typedef struct {
+	float x0, y0;
+	float x1, y1;
+} fz_rect;
+
+const fz_rect fz_infinite_rect = { 1, 1, -1, -1 };
+const fz_rect fz_empty_rect = { 0, 0, 0, 0 };
+const fz_rect fz_unit_rect = { 0, 0, 1, 1 };
+
+fz_rect fz_make_rect(float x0, float y0, float x1, float y1);
+</pre>
+
+<p>
+Our matrix structure is a row-major 3x3 matrix with the last column always [ 0 0 1 ].
+This is represented as a struct with six fields, in the same order as in PDF and Postscript.
+The identity matrix is a global constant, for easy access.
+
+<pre>
+/ a b 0 \
+| c d 0 |
+\ e f 1 /
+
+typedef struct {
+	float a, b, c, d, e, f;
+} fz_matrix;
+
+const fz_matrix fz_identity = { 1, 0, 0, 1, 0, 0 };
+
+fz_matrix fz_make_matrix(float a, float b, float c, float d, float e, float f);
+</pre>
+
+<p>
+Sometimes we need to represent a non-axis aligned rectangular-ish area, such
+as the area covered by some rotated text. For this we use a quad representation,
+using a points for each of the upper/lower/left/right corners as seen from
+the reading direction of the text represented.
+
+<pre>
+typedef struct {
+	fz_point ul, ur, ll, lr;
+} fz_quad;
+</pre>
+
+<p>
+List of math functions. These are simple mathematical operations that can not
+throw errors, so do not need a context argument.
+
+<pre>

+float fz_max(float a, float b);
+float fz_clamp(float f, float min, float max);
+
+int fz_absi(int i);
+int fz_mini(int a, int b);
+int fz_maxi(int a, int b);
+int fz_clampi(int i, int min, int max);

+
+<dl>
+<dt>fz_matrix fz_transform_page(fz_rect mediabox, float resolution, float rotate);
+<dd>
+Create a transform matrix to draw a page at a given resolution and rotation.

+Resolution is given in dots per inch.
+Rotation is expressed in degrees (0, 90, 180, and 270 are valid values).

+This module is a grab bag of various graphics related objects and functions.
+
+<h2>Colors</h2>
+
+<p>
+Colors throughout MuPDF are represented as a float vector associated with
+a colorspace object. Colorspaces come in many variants, the most common of
+which are Gray, RGB, and CMYK. We also support Indexed (palette), L*a*b*,
+Separation, DeviceN, and ICC based colorspaces.
+
+<pre>
+enum { FZ_MAX_COLORS = 32 };
+
+enum fz_colorspace_type {
+	FZ_COLORSPACE_NONE,
+	FZ_COLORSPACE_GRAY,
+	FZ_COLORSPACE_RGB,
+	FZ_COLORSPACE_BGR,
+	FZ_COLORSPACE_CMYK,
+	FZ_COLORSPACE_LAB,
+	FZ_COLORSPACE_INDEXED,
+	FZ_COLORSPACE_SEPARATION,
+};
+
+struct fz_colorspace_s {
+	enum fz_colorspace_type type;
+	int n;
+	char *name;
+	<i>private internal fields</i>
+};
+
+fz_colorspace *fz_keep_colorspace(fz_context *ctx, fz_colorspace *colorspace);
+void fz_drop_colorspace(fz_context *ctx, fz_colorspace *colorspace);
+</pre>
+
+<p>
+Most colorspaces have color components between 0 and 1.
+The number of components a color uses is given by the 'n' field
+of the colorspace. This is at most FZ_MAX_COLORS.
+
+<p>
+L*a*b* colors have a range of 0..100 for the L* and -128..127 for a* and b*.
+
+<p>
+CMYK, Separation, and DeviceN colorspaces are subtractive colorspaces.
+Separation and DeviceN colorspaces also have a tint transform function and
+a base colorspace used to represent the colors when rendering to a device that
+does not have these specific colorants.
+
+<h3>Color management engine</h3>
+
+<p>
+MuPDF is usually built with a color management engine, but this can be turned
+off at runtime if you need faster performance at the cost of much more
+inaccurate color conversions.
+
+<pre>
+int fz_enable_icc(fz_context *ctx);
+int fz_disable_icc(fz_context *ctx);
+</pre>
+
+<p>
+The various color conversion functions also take certain parameters that
+the color management engine uses, such as rendering intent and overprint
+control.
+
+<pre>
+enum {
+	FZ_RI_PERCEPTUAL,
+	FZ_RI_RELATIVE_COLORIMETRIC,
+	FZ_RI_SATURATION,
+	FZ_RI_ABSOLUTE_COLORIMETRIC,
+};
+
+typedef struct {
+	int ri; // Rendering intent
+	int bp; // Black point compensation
+	int op;
+	int opm;
+} fz_color_params;
+
+const fz_color_params fz_default_color_params = { FZ_RI_RELATIVE_COLORIMETRIC, 1, 0, 0 };
+</pre>
+
+<h3>Device colorspaces</h3>
+
+<p>
+When you need to define a color, and don't care too much about the calibration,
+you can use the Device colorspaces. When MuPDF is built with a color management
+engine and ICC is enabled the Gray and RGB colorspaces use an sRGB ICC profile.
+
+<pre>
+fz_colorspace *fz_device_gray(fz_context *ctx);
+fz_colorspace *fz_device_rgb(fz_context *ctx);
+fz_colorspace *fz_device_bgr(fz_context *ctx);
+fz_colorspace *fz_device_cmyk(fz_context *ctx);
+fz_colorspace *fz_device_lab(fz_context *ctx);
+</pre>
+
+<p>
+BGR is present to allow you to render to pixmaps that have the RGB components
+in a different order, so that the data can be passed directly to the operating
+system for drawing without needing yet another conversion step.
+
+<h3>Indexed colorspaces</h3>
+
+<p>
+Indexed colors have a range of 0..N where N is one less than the number of colors
+in the palette. An indexed colorspace also has a base colorspace, which is used
+to define the palette of colors used.
+
+<pre>
+fz_colorspace *fz_new_indexed_colorspace(fz_context *ctx,
+	fz_colorspace *base,
+	int high,
+	unsigned char *lookup);
+</pre>
+
+<p>
+High is the maximum value in the palette; i.e. one less than the number of colors.
+
+<p>
+The lookup argument is a packed array of color values in the base colorspace,
+represented as bytes mapped to the range of 0..255.
+
+<h3>ICC colorspaces</h3>
+
+<p>
+You can create ICC colorspaces from a buffer containing the ICC profile.
+
+<pre>
+fz_colorspace *fz_new_icc_colorspace(fz_context *ctx,
+	enum fz_colorspace_type type,
+	int flags,
+	const char *name,
+	fz_buffer *buf);
+</pre>
+
+<p>
+The 'type' argument can be NONE if you want to automatically infer the
+colorspace type from the profile data. If the type is anything else, then an
+error will be thrown if the profile does not match the type.
+
+<h3>Color converters</h3>
+
+<p>
+There are several ways to convert colors. The easiest is to call a function,
+but if you are converting many colors at once, it will be faster to use a
+color converter object.
+
+<pre>
+void fz_convert_color(fz_context *ctx,
+	fz_colorspace *src_colorspace,
+	const float *src_color,
+	fz_colorspace *dst_colorspace,
+	float *dst_color,
+	fz_colorspace *proof_colorspace,
+	const fz_color_params params);
+</pre>
+
+<pre>
+typedef struct {
+	void (*convert)(fz_context *ctx, fz_color_converter *cc, const float *src, float *dst);
+	<i>private internal fields</i>
+} fz_color_converter;
+
+void fz_find_color_converter(fz_context *ctx, fz_color_converter *cc,
+	fz_colorspace *src_colorspace,
+	fz_colorspace *dst_colorspace,
+	fz_colorspace *proof_colorspace,
+	fz_color_params params);
+void fz_drop_color_converter(fz_context *ctx, fz_color_converter *cc);
+</pre>
+
+<p>
+Here is some sample code to do a one-off CMYK to RGB color conversion.
+
+<pre>
+float cmyk[4] = { 1, 0, 0, 0 };
+float rgb[3];
+fz_convert_color(ctx, fz_device_cmyk(ctx), cmyk, fz_device_rgb(ctx), rgb, NULL, fz_default_color_params(ctx));
+</pre>
+
+<p>
+Here is some sample code to do repeated CMYK to RGB color conversions on many colors
+using a color converter object.
+
+<pre>
+float cmyk[100][4] = { {1,0,0,0}, ...
+float rgb[100][3];
+int i;
+fz_color_converter cc;
+fz_find_color_converter(ctx, &cc, fz_device_cmyk(ctx), fz_device_rgb(ctx), NULL, fz_default_color_params(ctx));
+for (i = 0; i < 100; ++i)
+	cc.convert(ctx, &cc, cmyk[i], rgb[i]);
+fz_drop_color_converter(ctx, &cc);
+</pre>
+
+<h2>Separations</h2>
+
+<p>
+TODO
+
+<h2>Pixmaps</h2>
+
+<p>
+A pixmap is an 8-bit per component raster image.
+Each pixel is packed with process colorants, spot colors, and alpha channel in that order.
+If an alpha channel is present, the process colorants are pre-multiplied with the alpha value.
+
+<pre>
+typedef struct {
+	int w, h; // Width and height
+	int x, y; // X and Y offset
+	int n; // Number of components in total (colors + spots + alpha)
+	int s; // Number of components that are spot colors
+	int alpha; // True if alpha channel is present
+	int stride; // Number of bytes per row
+	int xres, yres; // Resolution in dots per inch.
+	fz_colorspace *colorspace; // Colorspace of samples, or NULL if alpha only pixmap.
+	unsigned char *samples;
+	<i>private internal fields</i>
+} fz_pixmap;
+
+fz_pixmap *fz_keep_pixmap(fz_context *ctx, fz_pixmap *pix);
+void fz_drop_pixmap(fz_context *ctx, fz_pixmap *pix);
+</pre>
+
+<p>
+There are too many pixmap constructors. Here is the only one you should need.
+
+<pre>
+fz_pixmap *fz_new_pixmap(fz_context *ctx, fz_colorspace *cs, int w, int h, fz_separations *seps, int alpha);
+</pre>
+
+<p>
+A newly created pixmap has uninitialized data. The samples must either be
+cleared or overwritten with existing data before the pixmap can be safely used.
+
+<dl>
+<dt>void fz_clear_pixmap(fz_context *ctx, fz_pixmap *pix);
+<dd>Clear the pixmap to black.
+<dt>void fz_clear_pixmap_with_value(fz_context *ctx, fz_pixmap *pix, int value);
+<dd>Clear the pixmap to a grayscale value 0..255, where 0 is black and 255 is white.
+The value is automatically inverted for subtractive colorspaces.
+<dt>void fz_fill_pixmap_with_color(fz_context *ctx,
+	fz_pixmap *pix,
+	fz_colorspace *colorspace, float *color,
+	fz_color_params color_params);
+<dd>Fill the pixmap with a solid color.
+<dt>void fz_unpack_tile(fz_context *ctx, fz_pixmap *dst,
+	unsigned char *src,
+	int n,
+	int depth,
+	size_t stride,
+	int scale);
+<dd>Unpack pixel values from source data to fill in the pixmap samples. N is the number of samples per pixel, depth is the bit depth (1, 2, 4, 8, 16, 24, or 32), stride is the number of bytes per row. If scale is non-zero, it is the scaling factor to apply to the input samples to map them to the 8-bpc pixmap range. Pass 1 to the scale for indexed images, and 0 for everything else. If there are more components in the source data than the destination, they will be dropped. If there are fewer components in the source data, the pixmap will be padded with 255.
+</dl>
+
+<p>
+Some functions can create a pixmap and initialize its samples in one go:
+
+<pre>
+TODO: should these be public? make grayscale?
+fz_pixmap *fz_new_pixmap_from_8bpp_data(fz_context *ctx, int x, int y, int w, int h, unsigned char *data, int stride);
+fz_pixmap *fz_new_pixmap_from_1bpp_data(fz_context *ctx, int x, int y, int w, int h, unsigned char *data, int stride);
+</pre>
+
+<p>
+Pixmaps can be tinted, inverted, scaled, gamma corrected, and converted to other colorspaces.
+
+<dl>
+<dt>void fz_invert_pixmap(fz_context *ctx, fz_pixmap *pix);
+<dd>Invert the pixmap samples.
+<dt>void fz_tint_pixmap(fz_context *ctx, fz_pixmap *pix, int black, int white);
+<dd>Map black to black and white to white. The black and white colors are represented as a packed RGB integer. 0xFFFFFF is white, 0xFF0000 is red, and 0x000000 is black.
+<dt>void fz_gamma_pixmap(fz_context *ctx, fz_pixmap *pix, float gamma);
+<dd>Apply a gamma correction curve on the samples. A typical use is to adjust the gamma curve on an inverted image by applying a correction factor of 1/1.4.
+
+<dt>fz_pixmap *fz_convert_pixmap(fz_context *ctx,
+	fz_pixmap *source_pixmap,
+	fz_colorspace *destination_colorspace,
+	fz_colorspace *proof_colorspace,
+	fz_default_colorspaces *default_cs,
+	fz_color_params color_params,
+	int keep_alpha);
+<dd>Convert the source pixmap into the destination colorspace. Pass NULL for the default_cs parameter.
+
+<dt>fz_pixmap *fz_scale_pixmap(fz_context *ctx,
+	fz_pixmap *src,
+	float x,
+	float y,
+	float w,
+	float h,
+	const fz_irect *clip);
+<dd>Scale the pixmap up or down in size to fit the rectangle. Will return NULL
+if the scaling factors are out of whack. This applies fancy filtering and will
+anti-alias the edges for subpixel positioning if using non-integer coordinates.
+If the clip rectangle is set, the returned pixmap may be subset to
+fit the clip rectangle. Pass NULL to the clip if you want the whole pixmap
+scaled.

+<h1>MuPDF C API</h1>
+</header>
+
+<article>
+
+<h2>Introduction</h2>
+
+<p>
+This is the MuPDF C API guide -- for developers.
+In this document we will guide you through the public and stable bits of the MuPDF library.
+This is intended to both provide an introduction to new developers wanting to use
+low level features of MuPDF, and as a reference guide to the public interface.
+
+<p>
+We will be explaining the basics, enough to get you started on a single
+threaded application. There are more functions and data structures used
+internally, and there are also ways to use MuPDF from multiple threads,
+but those are beyond the scope of this document.
+
+<p>
+The functions and structures documented in this document are what we consider
+stable APIs. They will rarely change, and if they do, any such changes will be
+noted in the "api-changes" document along with instructions for how to update
+your code.
+
+<h2>MuPDF modules</h2>
+
+<p>
+MuPDF is separated into several modules.
+
+<dl>
+
+<dt><a href="core.html">Core</a>
+<dd>The core module contains the runtime context, exception handling, and
+various string manipulation, math, hash table, binary tree, and other useful
+functions.
+
+<dt><a href="io.html">I/O</a>
+<dd>The I/O module contains structures and functions for buffers of data,
+reading and writing to streams, compression, and encryption.
+
+<dt><a href="graphics.html">Graphics</a>
+<dd>The graphics module contains graphic resource objects like colors, fonts, shadings, and images.
+
+<dt>Device
+<dd>The device interface is how we provide access to the contents of a document.
+A device is a callback structure, that gets called for each piece of text,
+line art, and image on a page.
+There are several device implementations.
+The most important one renders the contents to a raster image, and another
+one gathers all the text into a structure that can be used to select
+and copy and search the text content on a page.
+
+<dt>Document
+<dd>The document module handles reading and writing documents in various
+formats, and ties together all the preceding modules to provide rendering,
+format conversion, and search functionality for the document types we support.
+
+<dt>PDF
+<dd>The PDF module provides access to the low level PDF structure, letting you
+query, modify, and create PDF objects and streams. It allows you to create new
+documents, modify existing documents, or examine features, extract data, or do
+almost anything you could want at the PDF object and stream level that we don't
+provide with the higher level APIs.

+
+<h2>Buffers</h2>
+
+<p>
+In order to represent a generic chunks of data we use the fz_buffer structure.
+
+<pre>
+typedef struct {
+	unsigned char *data;
+	size_t len; // current length
+	size_t cap; // total capacity
+	<i>reserved internal fields</i>
+} fz_buffer;
+
+fz_buffer *fz_keep_buffer(fz_context *ctx, fz_buffer *buf);
+void fz_drop_buffer(fz_context *ctx, fz_buffer *buf);
+</pre>
+
+<p>
+There are many ways to create a buffer. Some create a buffer shared immutable data,
+others with data you can edit, and others by copying or decoding other data.
+
+<dl>
+<dt>fz_buffer *fz_new_buffer(fz_context *ctx, size_t capacity);
+<dd>Create a new empty buffer, with the given initial capacity.
+<dt>fz_buffer *fz_new_buffer_from_shared_data(fz_context *ctx, const unsigned char *data, size_t size);
+<dd>Create a new buffer wrapping the given data pointer. The data is only referenced, and will not
+be freed when the buffer is destroyed. The data pointer must NOT change or disappear while the buffer lives.
+<dt>fz_buffer *fz_new_buffer_from_copied_data(fz_context *ctx, const unsigned char *data, size_t size);
+<dd>Create a buffer containing a copy of the data pointed to.
+<dt>fz_buffer *fz_new_buffer_from_base64(fz_context *ctx, const char *data, size_t size);
+<dd>Create a buffer containing the decoded BASE64 data.
+</dl>
+
+<p>
+Sometimes you want to create buffers piece by piece by appending strings or other data to it,
+while dynamically growing the underlying storage.
+
+<pre>
+void fz_append_data(fz_context *ctx, fz_buffer *buf, const void *data, size_t len);
+void fz_append_string(fz_context *ctx, fz_buffer *buf, const char *string);
+void fz_append_byte(fz_context *ctx, fz_buffer *buf, int byte);
+void fz_append_rune(fz_context *ctx, fz_buffer *buf, int rune);
+void fz_append_int16_be(fz_context *ctx, fz_buffer *buf, int x);
+void fz_append_int16_le(fz_context *ctx, fz_buffer *buf, int x);
+void fz_append_int32_be(fz_context *ctx, fz_buffer *buf, int x);
+void fz_append_int32_le(fz_context *ctx, fz_buffer *buf, int x);
+void fz_append_printf(fz_context *ctx, fz_buffer *buffer, const char *fmt, ...);
+void fz_append_vprintf(fz_context *ctx, fz_buffer *buffer, const char *fmt, va_list args);
+</pre>
+
+<p>
+You can also write a bit stream with the following functions.
+The buffer length always covers all the bits in the buffer, including
+any unused ones in the last byte, which will always be zero.
+
+<dl>
+<dt>void fz_append_bits(fz_context *ctx, fz_buffer *buf, int value, int count);
+<dd>Write the lower count bits from value into the buffer.
+<dt>void fz_append_bits_pad(fz_context *ctx, fz_buffer *buf);
+<dd>Write enough zero bits to be byte aligned.
+</dl>
+
+<p>
+You can use the buffer data as a zero-terminated C string by calling the following function.
+This will ensure that there is a zero terminator after the last byte and return
+a pointer to the first byte. This pointer is only borrowed, and should only be used
+briefly, before the buffer is changed again (which may reallocate or free the data).
+
+<pre>
+const char *fz_string_from_buffer(fz_context *ctx, fz_buffer *buf);
+</pre>
+
+<p>
+You can also read and write the contents of a buffer to file.
+
+<dl>
+<dt>fz_buffer *fz_read_file(fz_context *ctx, const char *filename);
+<dd>Read the contents of a file into a buffer.
+<dt>void fz_save_buffer(fz_context *ctx, fz_buffer *buf, const char *filename);
+<dd>Save the contents of a buffer to a file.
+</dl>
+
+<h2>Input Streams and Filters</h2>
+
+<p>
+An input stream reads data from a source. Some stream types can decompress and decrypt data,
+and these streams can be chained together in a pipeline.
+
+<pre>
+typedef struct { <i>internal</i> } fz_stream;
+
+fz_stream *fz_keep_stream(fz_context *ctx, fz_stream *stm);
+void fz_drop_stream(fz_context *ctx, fz_stream *stm);
+</pre>
+
+<dl>
+<dt>fz_stream *fz_open_file(fz_context *ctx, const char *filename);
+<dd>Open a stream reading the contents of a file.
+<dt>fz_stream *fz_open_memory(fz_context *ctx, const unsigned char *data, size_t len);
+<dd>Open a stream reading from the data pointer.
+<dt>fz_stream *fz_open_buffer(fz_context *ctx, fz_buffer *buf);
+<dd>Open a stream reading from a buffer.
+</dl>
+
+<p>
+The basic stream operations you expect are available.
+
+<pre>
+int64_t fz_tell(fz_context *ctx, fz_stream *stm);
+void fz_seek(fz_context *ctx, fz_stream *stm, int64_t offset, int whence);
+size_t fz_read(fz_context *ctx, fz_stream *stm, unsigned char *data, size_t len);
+size_t fz_skip(fz_context *ctx, fz_stream *stm, size_t len);
+</pre>
+
+<dl>
+<dt>fz_buffer *fz_read_all(fz_context *ctx, fz_stream *stm, size_t initial);
+<dd>Read the remaining data into a new buffer.
+
+<dt>char *fz_read_line(fz_context *ctx, fz_stream *stm, char *buf, size_t n);
+<dd>Behaves like fgets().
+</dl>
+
+<pre>
+int fz_read_byte(fz_context *ctx, fz_stream *stm);
+int fz_peek_byte(fz_context *ctx, fz_stream *stm);
+int fz_is_eof(fz_context *ctx, fz_stream *stm);
+</pre>
+
+<p>
+You can read binary data one integer at a time. The default is big endian, but LE versions are also
+provided.
+
+<pre>
+uint16_t fz_read_uint16(fz_context *ctx, fz_stream *stm);
+uint32_t fz_read_uint24(fz_context *ctx, fz_stream *stm);
+uint32_t fz_read_uint32(fz_context *ctx, fz_stream *stm);
+uint64_t fz_read_uint64(fz_context *ctx, fz_stream *stm);
+
+uint16_t fz_read_uint16_le(fz_context *ctx, fz_stream *stm);
+uint32_t fz_read_uint24_le(fz_context *ctx, fz_stream *stm);
+uint32_t fz_read_uint32_le(fz_context *ctx, fz_stream *stm);
+uint64_t fz_read_uint64_le(fz_context *ctx, fz_stream *stm);
+
+int16_t fz_read_int16(fz_context *ctx, fz_stream *stm);
+int32_t fz_read_int32(fz_context *ctx, fz_stream *stm);
+int64_t fz_read_int64(fz_context *ctx, fz_stream *stm);
+
+int16_t fz_read_int16_le(fz_context *ctx, fz_stream *stm);
+int32_t fz_read_int32_le(fz_context *ctx, fz_stream *stm);
+int64_t fz_read_int64_le(fz_context *ctx, fz_stream *stm);
+</pre>
+
+<p>
+Reading bit streams is also possible:
+
+<pre>
+unsigned int fz_read_bits(fz_context *ctx, fz_stream *stm, int n);
+unsigned int fz_read_rbits(fz_context *ctx, fz_stream *stm, int n);
+void fz_sync_bits(fz_context *ctx, fz_stream *stm);
+int fz_is_eof_bits(fz_context *ctx, fz_stream *stm);
+</pre>
+
+<p>
+Various decoding, decompression, and decryption filters can be chained together.
+
+<pre>
+fz_stream *fz_open_null_filter(fz_context *ctx, fz_stream *chain, int len, int64_t offset);
+fz_stream *fz_open_arc4(fz_context *ctx, fz_stream *chain, unsigned char *key, unsigned keylen);
+fz_stream *fz_open_aesd(fz_context *ctx, fz_stream *chain, unsigned char *key, unsigned keylen);
+fz_stream *fz_open_a85d(fz_context *ctx, fz_stream *chain);
+fz_stream *fz_open_ahxd(fz_context *ctx, fz_stream *chain);
+fz_stream *fz_open_rld(fz_context *ctx, fz_stream *chain);
+fz_stream *fz_open_flated(fz_context *ctx, fz_stream *chain, int window_bits);
+
+fz_stream *fz_open_dctd(fz_context *ctx, fz_stream *chain,
+	int color_transform,
+	int l2factor,
+	fz_stream *jpegtables);
+
+fz_stream *fz_open_faxd(fz_context *ctx, fz_stream *chain,
+	int k,
+	int end_of_line,
+	int encoded_byte_align,
+	int columns,
+	int rows,
+	int end_of_block,
+	int black_is_1);
+
+fz_stream *fz_open_lzwd(fz_context *ctx, fz_stream *chain,
+	int early_change,
+	int min_bits,
+	int reverse_bits,
+	int old_tiff);
+
+fz_stream *fz_open_predict(fz_context *ctx, fz_stream *chain,
+	int predictor,
+	int columns,
+	int colors,
+	int bpc);
+</pre>
+
+<h2>Output Streams and Filters</h2>
+
+<p>
+Output streams let us write data to a sink, usually a file on disk or a buffer.
+As with the input streams, output streams can be chained together to compress,
+encrypt, and encode data.
+
+<pre>
+typedef struct { <i>internal</i> } fz_output;
+</pre>
+
+<p>
+Because output may be buffered in the writer, we need a separate
+close function to ensure that an output stream is properly flushed
+and any end of data markers are written. This is separate to the
+drop function, which just frees data. If a writing operation has
+succeeded, you need to call close on the output stream before
+dropping it.
+If you encounter an error while writing data, you can just drop the stream directly, since
+we couldn't finish writing it and closing it properly would be irrelevant.
+
+<pre>
+void fz_close_output(fz_context *ctx, fz_output *out);
+void fz_drop_output(fz_context *ctx, fz_output *out);
+</pre>
+
+<p>
+Outputs can be created to write to files or buffers.
+You can also implement your own data sink by providing a state pointer
+and callback functions.
+
+<pre>
+fz_output *fz_new_output_with_path(fz_context *, const char *filename, int append);
+fz_output *fz_new_output_with_buffer(fz_context *ctx, fz_buffer *buf);
+
+fz_output *fz_new_output(fz_context *ctx,
+	int buffer_size,
+	void *state,
+	void (*write)(fz_context *ctx, void *state, const void *data, size_t n),
+	void (*close)(fz_context *ctx, void *state),
+	void (*drop)(fz_context *ctx, void *state));
+</pre>
+
+<p>
+The usual suspects are available, as well as functions to write
+integers of various sizes and byte orders.
+
+<dl>
+<dt>void fz_seek_output(fz_context *ctx, fz_output *out, int64_t off, int whence);
+<dd>Seek to a location in the output. This is not available for all output types.
+<dt>int64_t fz_tell_output(fz_context *ctx, fz_output *out);
+<dd>Tell the current write location of the output stream.
+</dl>
+
+<pre>
+void fz_write_data(fz_context *ctx, fz_output *out, const void *data, size_t size);
+void fz_write_string(fz_context *ctx, fz_output *out, const char *s);
+void fz_write_byte(fz_context *ctx, fz_output *out, unsigned char x);
+void fz_write_rune(fz_context *ctx, fz_output *out, int rune);
+void fz_write_int16_be(fz_context *ctx, fz_output *out, int x);
+void fz_write_int16_le(fz_context *ctx, fz_output *out, int x);
+void fz_write_int32_be(fz_context *ctx, fz_output *out, int x);
+void fz_write_int32_le(fz_context *ctx, fz_output *out, int x);
+void fz_write_printf(fz_context *ctx, fz_output *out, const char *fmt, ...);
+void fz_write_vprintf(fz_context *ctx, fz_output *out, const char *fmt, va_list ap);
+void fz_write_base64(fz_context *ctx, fz_output *out, const unsigned char *data, int size, int newline);
+</pre>
+
+<p>
+Output streams can be chained together to add encryption, compression, and
+encoding. Note that these do not take ownership of the chained stream, they
+only write to it. For example, you can write a header, create a compression
+filter stream, write some data to the filter to compress the data, close the
+filter and then keep writing more data to the original stream.
+
+<pre>
+fz_output *fz_new_arc4_output(fz_context *ctx, fz_output *chain, unsigned char *key, size_t keylen);
+fz_output *fz_new_ascii85_output(fz_context *ctx, fz_output *chain);
+fz_output *fz_new_asciihex_output(fz_context *ctx, fz_output *chain);
+fz_output *fz_new_deflate_output(fz_context *ctx, fz_output *chain, int effort, int no_header);
+fz_output *fz_new_rle_output(fz_context *ctx, fz_output *chain);
+</pre>
+
+<h2>File Archives</h2>
+
+<p>
+The archive structure is a read-only collection of files. This is typically a
+Zip file or directory on disk, but other formats are also supported.
+
+<pre>
+typedef struct { <i>internal</i> } fz_archive;
+
+void fz_drop_archive(fz_context *ctx, fz_archive *arch);
+
+int fz_is_directory(fz_context *ctx, const char *path);
+
+fz_archive *fz_open_directory(fz_context *ctx, const char *path);
+fz_archive *fz_open_archive(fz_context *ctx, const char *filename);
+fz_archive *fz_open_archive_with_stream(fz_context *ctx, fz_stream *file);
+
+int fz_count_archive_entries(fz_context *ctx, fz_archive *arch);
+const char *fz_list_archive_entry(fz_context *ctx, fz_archive *arch, int idx);
+
+int fz_has_archive_entry(fz_context *ctx, fz_archive *arch, const char *name);
+fz_stream *fz_open_archive_entry(fz_context *ctx, fz_archive *arch, const char *name);
+fz_buffer *fz_read_archive_entry(fz_context *ctx, fz_archive *arch, const char *name);
+</pre>
+
+<p>
+We can also create new Zip archives.
+
+<pre>
+typedef struct { <i>internal</i> } fz_zip_writer;
+
+fz_zip_writer *fz_new_zip_writer(fz_context *ctx, const char *filename);
+fz_zip_writer *fz_new_zip_writer_with_output(fz_context *ctx, fz_output *out);
+void fz_write_zip_entry(fz_context *ctx, fz_zip_writer *zip, const char *name, fz_buffer *buf, int compress);
+void fz_close_zip_writer(fz_context *ctx, fz_zip_writer *zip);
+void fz_drop_zip_writer(fz_context *ctx, fz_zip_writer *zip);

+
+<h2>Download</h2>
+
+<p>
+The latest development source is available directly from the git repository:
+
+<pre>
+git clone --recursive git://git.ghostscript.com/mupdf.git
+</pre>
+
+<p>
+In the mupdf directory, update the third party libraries:
+
+<pre>
+git submodule update --init
+</pre>
+
+<h2>Compiling on Windows</h2>
+
+<p>
+On Windows there is a Visual Studio project file in <tt>platform/win32/mupdf.vcproj</tt>.
+
+<h2>Compiling on Linux</h2>
+
+<p>
+If you are compiling from source you will need several third party libraries:
+freetype2, jbig2dec, libjpeg, openjpeg, and zlib. These libraries are contained
+in the source archive. If you are using git, they are included as git
+submodules.
+
+<p>
+You will also need the X11 headers and libraries if you're building on Linux.
+These can typically be found in the xorg-dev package. Alternatively, if you
+only want the command line tools, you can build with HAVE_X11=no.
+
+<p>
+The new OpenGL-based viewer also needs OpenGL headers and libraries. If you're
+building on Linux, install the mesa-common-dev, libgl1-mesa-dev packages, and
+libglu1-mesa-dev packages. You'll also need several X11 development packages:
+xorg-dev, libxcursor-dev, libxrandr-dev, and libxinerama-dev. To skip building
+the OpenGL viewer, build with HAVE_GLUT=no.
+
+<p>
+To install the viewer, command line tools, libraries, and header files on your system:
+
+<pre>
+make prefix=/usr/local install
+</pre>
+
+<p>
+To install only the command line tools, libraries, and headers invoke make like this:
+
+<pre>
+make HAVE_X11=no HAVE_GLUT=no prefix=/usr/local install
+</pre>

+Basic MuPDF usage example
+</h2>
+
+<p>
+For an example of how to use MuPDF in the most basic way, see
+<a href="examples/example.c">docs/examples/example.c</a>.
+To limit the complexity and give an easier introduction
+this code has no error handling at all, but any serious piece of code
+using MuPDF should use the error handling strategies described below.
+
+<h2><a id="common-function-arguments"></a>
+Common function arguments
+</h2>
+
+<p>
+Most functions in MuPDF's interface take a context argument.
+
+<p>
+A context contains global state used by MuPDF inside functions when
+parsing or rendering pages of the document. It contains for example:
+
+<ul>
+<li> an exception stack (see error handling below),
+<li> a memory allocator (allowing for custom allocators)
+<li> a resource store (for caching of images, fonts, etc.)
+<li> a set of locks and (un-)locking functions (for multi-threading)
+</ul>
+
+<p>
+Without the set of locks and accompanying functions the context and
+its proxies may only be used in a single-threaded application.
+
+<h2><a id="error-handling"></a>
+Error handling
+</h2>
+
+<p>
+MuPDF uses a set of exception handling macros to simplify error return
+and cleanup. Conceptually, they work a lot like C++'s try/catch
+system, but do not require any special compiler support.
+
+<p>
+The basic formulation is as follows:
+
+<pre>
+fz_try(ctx)
+{
+	// Try to perform a task. Never 'return', 'goto' or
+	// 'longjmp' out of here. 'break' may be used to
+	// safely exit (just) the try block scope.
+}
+fz_always(ctx)
+{
+	// Any code here is always executed, regardless of
+	// whether an exception was thrown within the try or
+	// not. Never 'return', 'goto' or longjmp out from
+	// here. 'break' may be used to safely exit (just) the
+	// always block scope.
+}
+fz_catch(ctx)
+{
+	// This code is called (after any always block) only
+	// if something within the fz_try block (including any
+	// functions it called) threw an exception. The code
+	// here is expected to handle the exception (maybe
+	// record/report the error, cleanup any stray state
+	// etc) and can then either exit the block, or pass on
+	// the exception to a higher level (enclosing) fz_try
+	// block (using fz_throw, or fz_rethrow).
+}
+</pre>
+
+<p>
+The fz_always block is optional, and can safely be omitted.
+
+<p>
+The macro based nature of this system has 3 main limitations:
+
+<ol>
+<li>	<p>
+	Never return from within try (or 'goto' or longjmp out of it).
+	This upsets the internal housekeeping of the macros and will
+	cause problems later on. The code will detect such things
+	happening, but by then it is too late to give a helpful error
+	report as to where the original infraction occurred.
+
+<li>	<p>
+	The fz_try(ctx) { ... } fz_always(ctx) { ... } fz_catch(ctx) { ... }
+	is not one atomic C statement. That is to say, if you do:
+<pre>
+if (condition)
+	fz_try(ctx) { ... }
+	fz_catch(ctx) { ... }
+</pre>
+	then you will not get what you want. Use the following instead:
+<pre>
+if (condition) {
+	fz_try(ctx) { ... }
+	fz_catch(ctx) { ... }
+}
+</pre>
+
+<li>	<p>
+	The macros are implemented using setjmp and longjmp, and so
+	the standard C restrictions on the use of those functions
+	apply to fz_try/fz_catch too. In particular, any "truly local"
+	variable that is set between the start of fz_try and something
+	in fz_try throwing an exception may become undefined as part
+	of the process of throwing that exception.
+
+	<p>
+	As a way of mitigating this problem, we provide a fz_var()
+	macro that tells the compiler to ensure that that variable is
+	not unset by the act of throwing the exception.
+</ol>
+
+<p>
+A model piece of code using these macros then might be:
+
+<pre>
+house build_house(plans *p)
+{
+	material m = NULL;
+	walls w = NULL;
+	roof r = NULL;
+	house h = NULL;
+	tiles t = make_tiles();
+
+	fz_var(w);
+	fz_var(r);
+	fz_var(h);
+
+	fz_try(ctx)
+	{
+		fz_try(ctx)
+		{
+			m = make_bricks();
+		}
+		fz_catch(ctx)
+		{
+			// No bricks available, make do with straw?
+			m = make_straw();
+		}
+		w = make_walls(m, p);
+		r = make_roof(m, t);
+		// Note, NOT: return combine(w,r);
+		h = combine(w, r);
+	}
+	fz_always(ctx)
+	{
+		drop_walls(w);
+		drop_roof(r);
+		drop_material(m);
+		drop_tiles(t);
+	}
+	fz_catch(ctx)
+	{
+		fz_throw(ctx, "build_house failed");
+	}
+	return h;
+}
+</pre>
+
+<p>
+Things to note about this:
+
+<ol>
+<li>	If make_tiles throws an exception, this will immediately be
+	handled by some higher level exception handler. If it
+	succeeds, t will be set before fz_try starts, so there is no
+	need to fz_var(t);
+
+<li>	We try first off to make some bricks as our building material.
+	If this fails, we fall back to straw. If this fails, we'll end
+	up in the fz_catch, and the process will fail neatly.
+
+<li>	We assume in this code that combine takes new reference to
+	both the walls and the roof it uses, and therefore that w and
+	r need to be cleaned up in all cases.
+
+<li>	We assume the standard C convention that it is safe to destroy
+	NULL things.
+</ol>
+
+<h2><a id="multi-threading"></a>
+Multi-threading
+</h2>
+
+<p>
+First off, study the basic usage example in
+<a href="examples/example.c">docs/examples/example.c</a>
+and make sure you understand how it works as the data structures manipulated
+there will be referred to in this section too.
+
+<p>
+MuPDF can usefully be built into a multi-threaded application without
+the library needing to know anything threading at all. If the library
+opens a document in one thread, and then sits there as a 'server'
+requesting pages and rendering them for other threads that need them,
+then the library is only ever being called from this one thread.
+
+<p>
+Other threads can still be used to handle UI requests etc, but as far
+as MuPDF is concerned it is only being used in a single threaded way.
+In this instance, there are no threading issues with MuPDF at all,
+and it can safely be used without any locking, as described in the
+previous sections.
+
+<p>
+This section will attempt to explain how to use MuPDF in the more
+complex case; where we genuinely want to call the MuPDF library
+concurrently from multiple threads within a single application.
+
+<p>
+MuPDF can be invoked with a user supplied set of locking functions.
+It uses these to take mutexes around operations that would conflict
+if performed concurrently in multiple threads. By leaving the
+exact implementation of locks to the caller MuPDF remains threading
+library agnostic.
+
+<p>
+The following simple rules should be followed to ensure that
+multi-threaded operations run smoothly:
+
+<ol>
+<li>	<p>
+	"No simultaneous calls to MuPDF in different threads are
+	allowed to use the same context."
+
+	<p>
+	Most of the time it is simplest to just use a different
+	context for every thread; just create a new context at the
+	same time as you create the thread. For more details see
+	"Cloning the context" below.
+
+<li>	<p>
+	"No simultaneous calls to MuPDF in different threads are
+	allowed to use the same document."
+
+	<p>
+	Only one thread can be accessing a document at a time, but
+	once display lists are created from that document, multiple
+	threads at a time can operate on them.
+
+	<p>
+	The document can be used from several different threads as
+	long as there are safeguards in place to prevent the usages
+	being simultaneous.
+
+<li>	<p>
+	"No simultaneous calls to MuPDF in different threads are
+	allowed to use the same device."
+
+	<p>
+	Calling a device simultaneously from different threads will
+	cause it to get confused and may crash. Calling a device from
+	several different threads is perfectly acceptable as long as
+	there are safeguards in place to prevent the calls being
+	simultaneous.
+</ol>
+
+<p>
+So, how does a multi-threaded example differ from a non-multithreaded
+one?
+
+<p>
+Firstly, when we create the first context, we call fz_new_context
+as before, but the second argument should be a pointer to a set
+of locking functions.
+
+<p>
+The calling code should provide FZ_LOCK_MAX mutexes, which will be
+locked/unlocked by MuPDF calling the lock/unlock function pointers
+in the supplied structure with the user pointer from the structure
+and the lock number, i (0 &lt;= i &lt; FZ_LOCK_MAX). These mutexes can
+safely be recursive or non-recursive as MuPDF only calls in a non-
+recursive style.
+
+<p>
+To make subsequent contexts, the user should NOT call fz_new_context
+again (as this will fail to share important resources such as the
+store and glyphcache), but should rather call fz_clone_context.
+Each of these cloned contexts can be freed by fz_free_context as
+usual. They will share the important data structures (like store,
+glyph cache etc) with the original context, but will have their
+own exception stacks.
+
+<p>
+To open a document, call fz_open_document as usual, passing a context
+and a filename. It is important to realise that only one thread at a
+time can be accessing the documents itself.
+
+<p>
+This means that only one thread at a time can perform operations such
+as fetching a page, or rendering that page to a display list. Once a
+display list has been obtained however, it can be rendered from any
+other thread (or even from several threads simultaneously, giving
+banded rendering).
+
+<p>
+This means that an implementer has 2 basic choices when constructing
+an application to use MuPDF in multi-threaded mode. Either he can
+construct it so that a single nominated thread opens the document
+and then acts as a 'server' creating display lists for other threads
+to render, or he can add his own mutex around calls to mupdf that
+use the document. The former is likely to be far more efficient in
+the long run.
+
+<p>
+For an example of how to do multi-threading see
+<a href="examples/multi-threaded.c">docs/examples/multi-threaded.c</a>
+which has a main thread and one rendering thread per page.
+
+<h2><a id="cloning-the-context"></a>
+Cloning the context
+</h2>
+
+<p>
+As described above, every context contains an exception stack which is
+manipulated during the course of nested fz_try/fz_catches. For obvious
+reasons the same exception stack cannot be used from more than one
+thread at a time.
+
+<p>
+If, however, we simply created a new context (using fz_new_context) for
+every thread, we would end up with separate stores/glyph caches etc,
+which is not (generally) what is desired. MuPDF therefore provides a
+mechanism for "cloning" a context. This creates a new context that
+shares everything with the given context, except for the exception
+stack.
+
+<p>
+A commonly used general scheme is therefore to create a 'base' context
+at program start up, and to clone this repeatedly to get new contexts
+that can be used on new threads.

+<h1>MuPDF Progressive Loading</h1>
+</header>
+
+<article>
+
+<p>
+How to do progressive loading with MuPDF.
+
+<h2>What is progressive loading?</h2>
+
+<p>
+The idea of progressive loading is that as you download a PDF file
+into a browser, you can display the pages as they appear.
+
+<p>
+MuPDF can make use of 2 different mechanisms to achieve this. The
+first relies on the file being "linearized", the second relies on
+the caller of MuPDF having fine control over the http fetch and on
+the server supporting byte-range fetches.
+
+<p>
+For optimum performance a file should be both linearized and be
+available over a byte-range supporting link, but benefits can still
+be had with either one of these alone.
+
+<h2>Progressive download using "linearized" files</h2>
+
+<p>
+Adobe defines "linearized" PDFs as being ones that have both a
+specific layout of objects and a small amount of extra
+information to help avoid seeking within a file. The stated aim
+is to deliver the first page of a document in advance of the whole
+document downloading, whereupon subsequent pages will become
+available. Adobe also refers to these as "Optimized for fast web
+view" or "Web Optimized".
+
+<p>
+In fact, the standard outlines (poorly) a mechanism by which 'hints'
+can be included that enable the subsequent pages to be found within
+the file too. Unfortunately this is very poorly supported with
+many tools, and so the hints have to be treated with suspicion.
+
+<p>
+MuPDF will attempt to use hints if they are available, but will also
+use a linear search of the file to discover pages if not. This means
+that the first page will be displayed quickly, and then subsequent
+ones will appear with 'incomplete' renderings that improve over time
+as more and more resources are gradually delivered.
+
+<p>
+Essentially the file starts with a slightly modified header, and the
+first object in the file is a special one (the linearization object)
+that a) indicates that the file is linearized, and b) gives some
+useful information (like the number of pages in the file etc).
+
+<p>
+This object is then followed by all the objects required for the
+first page, then the "hint stream", then sets of object for each
+subsequent page in turn, then shared objects required for those
+pages, then various other random things.
+
+<p>
+[Yes, really. While page 1 is sent with all the objects that it
+uses, shared or otherwise, subsequent pages do not get shared
+resources until after all the unshared page objects have been
+sent.]
+
+<h2>The Hint Stream</h2>
+
+<p>
+Adobe intended Hint Stream to be useful to facilitate the display
+of subsequent pages, but it has never used it. Consequently you
+can't trust people to write it properly - indeed Adobe outputs
+something that doesn't quite conform to the spec.
+
+<p>
+Consequently very few people actually use it. MuPDF will use it
+after sanity checking the values, and should cope with illegal/
+incorrect values.
+
+<h2>So how does MuPDF handle progressive loading?</h2>
+
+<p>
+MuPDF has made various extensions to its mechanisms for handling
+progressive loading.
+
+<ul>
+	<li> Progressive streams
+
+		<p>
+		At its lowest level MuPDF reads file data from a fz_stream,
+		using the fz_open_document_with_stream call. (fz_open_document
+		is implemented by calling this). We have extended the fz_stream
+		slightly, giving the system a way to ask for meta information
+		(or perform meta operations) on a stream.
+
+		<p>
+		Using this mechanism MuPDF can query:
+
+		<ul>
+			<li> whether a stream is progressive or not (i.e. whether the
+				entire stream is accessible immediately)
+			<li> what the length of a stream should ultimately be (which an
+				http fetcher should know from the Content-Length header),
+		</ul>
+
+		<p>
+		With this information MuPDF can decide whether to use its normal
+		object reading code, or whether to make use of a linearized
+		object. Knowing the length enables us to check with the length
+		value given in the linearized object - if these differ, the
+		assumption is that an incremental save has taken place, thus the
+		file is no longer linearized.
+
+		<p>
+		When data is pulled from a progressive stream, if we attempt to
+		read data that is not currently available, the stream should
+		throw a FZ_ERROR_TRYLATER error. This particular error code
+		will be interpreted by the caller as an indication that it
+		should retry the parsing of the current objects at a later time.
+
+		<p>
+		When a MuPDF call is made on a progressive stream, such as
+		fz_open_document_with_stream, or fz_load_page, the caller should
+		be prepared to handle a FZ_ERROR_TRYLATER error as meaning that
+		more data is required before it can continue. No indication is
+		directly given as to exactly how much more data is required, but
+		as the caller will be implementing the progressive fz_stream
+		that it has passed into MuPDF to start with, it can reasonably
+		be expected to figure out an estimate for itself.
+
+	<li> Cookie
+
+		<p>
+		Once a page has been loaded, if its contents are to be 'run'
+		as normal (using e.g. fz_run_page) any error (such as failing
+		to read a font, or an image, or even a content stream belonging
+		to the page) will result in a rendering that aborts with an
+		FZ_ERROR_TRYLATER error. The caller can catch this and display
+		a placeholder instead.
+
+		<p>
+		If each pages data was entirely self-contained and sent in
+		sequence this would perhaps be acceptable, with each page
+		appearing one after the other. Unfortunately, the linearization
+		procedure as laid down by Adobe does NOT do this: objects shared
+		between multiple pages (other than the first) are not sent with
+		the pages themselves, but rather AFTER all the pages have been
+		sent.
+
+		<p>
+		This means that a document that has a title page, then contents
+		that share a font used on pages 2 onwards, will not be able to
+		correctly display page 2 until after the font has arrived in
+		the file, which will not be until all the page data has been
+		sent.
+
+		<p>
+		To mitigate against this, MuPDF provides a way whereby callers
+		can indicate that they are prepared to accept an 'incomplete'
+		rendering of the file (perhaps with missing images, or with
+		substitute fonts).
+
+		<p>
+		Callers prepared to tolerate such renderings should set the
+		'incomplete_ok' flag in the cookie, then call fz_run_page etc
+		as normal. If a FZ_ERROR_TRYLATER error is thrown at any point
+		during the page rendering, the error will be swallowed, the
+		'incomplete' field in the cookie will become non-zero and
+		rendering will continue. When control returns to the caller
+		the caller can check the value of the 'incomplete' field and
+		know that the rendering it received is not authoritative.
+
+</ul>
+
+<h2>Progressive loading using byte range requests</h2>
+
+<p>
+If the caller has control over the http fetch, then it is possible
+to use byte range requests to fetch the document 'out of order'.
+This enables non-linearized files to be progressively displayed as
+they download, and fetches complete renderings of pages earlier than
+would otherwise be the case. This process requires no changes within
+MuPDF itself, but rather in the way the progressive stream learns
+from the attempts MuPDF makes to fetch data.
+
+<p>
+Consider for example, an attempt to fetch a hypothetical file from
+a server.
+
+<ul>
+	<li><p>
+	The initial http request for the document is sent with a "Range:"
+	header to pull down the first (say) 4k of the file.
+
+	<li><p>
+	As soon as we get the header in from this initial request, we can
+	respond to meta stream operations to give the length, and whether
+	byte requests are accepted.
+
+	<ul>
+		<li><p>
+		If the header indicates that byte ranges are acceptable the
+		stream proceeds to go into a loop fetching chunks of the file
+		at a time (not necessarily in-order). Otherwise the server
+		will ignore the Range: header, and just serve the whole file.
+
+		<li><p>
+		If the header indicates a content-length, the stream returns
+		that.
+	</ul>
+
+	<li><p>
+	MuPDF can then decide how to proceed based upon these flags and
+	whether the file is linearized or not. (If the file contains a
+	linearized object, and the content length matches, then the file
+	is considered to be linear, otherwise it is not).
+
+	<p>
+	If the file is linear:
+
+	<ul>
+		<li><p>
+		We proceed to read objects out of the file as it downloads.
+		This will provide us the first page and all its resources. It
+		will also enable us to read the hint streams (if present).
+
+		<li><p>
+		Once we have read the hint streams, we unpack (and sanity
+		check) them to give us a map of where in the file each object
+		is predicted to live, and which objects are required for each
+		page. If any of these values are out of range, we treat the
+		file as if there were no hint streams.
+
+		<li><p>
+		If we have hints, any attempt to load a subsequent page will
+		cause MuPDF to attempt to read exactly the objects required.
+		This will cause a sequence of seeks in the fz_stream followed
+		by reads. If the stream does not have the data to satisfy that
+		request yet, the stream code should remember the location that
+		was fetched (and fetch that block in the background so that
+		future retries will succeed) and should raise an
+		FZ_ERROR_TRYLATER error.
+
+		<p>
+		[Typically therefore when we jump to a page in a linear file
+		on a byte request capable link, we will quickly see a rough
+		rendering, which will improve fairly fast as images and fonts
+		arrive.]
+
+		<li><p>
+		Regardless of whether we have hints or byte requests, on every
+		fz_load_page call MuPDF will attempt to process more of the
+		stream (that is assumed to be being downloaded in the
+		background). As linearized files are guaranteed to have pages
+		in order, pages will gradually become available. In the absence
+		of byte requests and hints however, we have no way of getting
+		resources early, so the renderings for these pages will remain
+		incomplete until much more of the file has arrived.
+
+		<p>
+		[Typically therefore when we jump to a page in a linear file
+		on a non byte request capable link, we will see a rough
+		rendering for that page as soon as data arrives for it (which
+		will typically take much longer than would be the case with
+		byte range capable downloads), and that will improve much more
+		slowly as images and fonts may not appear until almost the
+		whole file has arrived.]
+
+		<li><p>
+		When the whole file has arrived, then we will attempt to read
+		the outlines for the file.
+	</ul>
+
+	<p>
+	For a non-linearized PDF on a byte request capable stream:
+
+	<ul>
+		<li><p>
+		MuPDF will immediately seek to the end of the file to attempt
+		to read the trailer. This will fail with a FZ_ERROR_TRYLATER
+		due to the data not being here yet, but the stream code should
+		remember that this data is required and it should be prioritized
+		in the background fetch process.
+
+		<li><p>
+		Repeated attempts to open the stream should eventually succeed
+		therefore. As MuPDF jumps through the file trying to read first
+		the xrefs, then the page tree objects, then the page contents
+		themselves etc, the background fetching process will be driven
+		by the attempts to read the file in the foreground.
+
+		<p>
+		[Typically therefore the opening of a non-linearized file will
+		be slower than a linearized one, as the xrefs/page trees for a
+		non-linear file can be 20%+ of the file data. Once past this
+		initial point however, pages and data can be pulled from the
+		file almost as fast as with a linearized file.]
+	</ul>
+
+	<p>
+	For a non-linearized PDF on a non-byte request capable stream:
+
+	<ul>
+		<li><p>
+		MuPDF will immediately seek to the end of the file to attempt
+		to read the trailer. This will fail with a FZ_ERROR_TRYLATER
+		due to the data not being here yet. Subsequent retries will
+		continue to fail until the whole file has arrived, whereupon
+		the whole file will be instantly available.
+
+		<p>
+		[This is the worst case situation - nothing at all can be
+		displayed until the entire file has downloaded.]
+	</ul>
+
+	<p>
+	A typical structure for a fetcher process (see curl-stream.c in
+	mupdf-curl as an example) might therefore look like this:
+
+	<ul>
+		<li><p>
+		We consider the file as an (initially empty) buffer which we are
+		filling by making requests. In order to ensure that we make
+		maximum use of our download link, we ensure that whenever
+		one request finishes, we immediately launch another. Further, to
+		avoid the overheads for the request/response headers being too
+		large, we may want to divide the file into 'chunks', perhaps 4 or 32k
+		in size.
+
+		<li><p>
+		We can then have a receiver process that sits there in a loop
+		requesting chunks to fill this buffer. In the absence of
+		any other impetus the receiver should request the next 'chunk'
+		of data from the file that it does not yet have, following the last
+		fill point. Initially we start the fill point at the beginning of
+		the file, but this will move around based on the requests made of
+		the progressive stream.
+
+		<li><p>
+		Whenever MuPDF attempts to read from the stream, we check to see if
+		we have data for this area of the file already. If we do, we can
+		return it. If not, we remember this as the next "fill point" for our
+		receiver process and throw a FZ_ERROR_TRYLATER error.
+	</ul>
+

+<h1>MuPDF Coding Style</h1>
+</header>
+
+<article>
+
+<h2>Names</h2>
+
+<p>
+Functions should be named according to one of the following schemes:
+
+<ul>
+<li> verb_noun
+<li> verb_noun_with_noun
+<li> noun_attribute
+<li> set_noun_attribute
+<li> noun_from_noun -- convert from one type to another (avoid noun_to_noun)
+</ul>
+
+<p>
+Prefixes are mandatory for exported functions, macros, enums, globals and types.
+
+<ul>
+<li> fz for common code
+<li> pdf, xps, etc., for interpreter specific code
+</ul>
+
+<p>
+Prefixes are optional (but encouraged) for private functions and types.
+
+<p>
+Avoid using 'get' as this is a meaningless and redundant filler word.
+
+<p>
+These words are reserved for reference counting schemes:
+
+<ul>
+<li> new, find, load, open, keep -- return objects that you are responsible for freeing.
+
+<li> drop -- relinquish ownership of the object passed in.
+</ul>
+
+<p>
+When searching for an object or value, the name used depends on whether
+returning the value is passing ownership:
+
+<ul>
+<li> lookup -- return a value or borrowed pointer
+<li> find -- return an object that the caller is responsible for freeing
+</ul>
+
+<h2>Types</h2>
+
+<p>
+Various different integer types are used throughout MuPDF.
+
+<p>
+In general:
+
+<ul>
+<li> int is assumed to be 32bit at least.
+<li> short is assumed to be exactly 16 bits.
+<li> char is assumed to be exactly 8 bits.
+<li> array sizes, string lengths, and allocations are measured using size_t.
+	size_t is 32bit in 32bit builds, and 64bit on all 64bit builds.
+<li> buffers of data use unsigned chars (or uint8_t).
+<li> Offsets within files/streams are represented using int64_t.
+</ul>
+
+<p>
+In addition, we use floats (and avoid doubles when possible), assumed to be IEEE compliant.
+
+<h2>Reference counting</h2>
+
+<p>
+Reference counting uses special words in functions to make it easy to remember
+and follow the rules.

+<p>
+Words that take ownership: new, find, load, open, keep.
+
+<p>
+Words that release ownership: drop.
+
+<p>
+If an object is returned by a function with one of the special words that take
+ownership, you are responsible for freeing it by calling "drop" or "free", or
+"close" before you return. You may pass ownership of an owned object by return
+it only if you name the function using one of the special words.
+
+<p>
+Any objects returned by functions that do not have any of these special words,
+are borrowed and have a limited life time. Do not hold on to them past the
+duration of the current function, or stow them away inside structs. If you need
+to keep the object for longer than that, you have to either "keep" it or make
+your own copy.

+<h1>MuPDF Documentation</h1>
+</header>
+
+<article>
+
+<p>
+MuPDF is an open source software framework for viewing and converting PDF, XPS, and E-book documents.
+There are viewers for various platforms,
+several command line tools,
+and a software library for building tools and applications.
+
+<h2>Viewers</h2>
+
+<p>
+For Linux and Windows there are two viewers. One is a very basic viewer using x11 and win32, respectively.
+It has been supplanted by a newer viewer using OpenGL for rendering, which has more features
+such as table of contents, unicode search, etc.
+We keep the old viewers around for older systems where OpenGL is not available.
+
+<p>
+Read the <a href="manual-mupdf-gl.html">manual for the new Linux and Windows viewer</a>.
+
+<p>
+Android currently has several different viewers with varying degrees of complexity:
+
+<dl>
+<dt><a href="https://play.google.com/store/apps/details?id=com.artifex.mupdfdemo">MuPDF</a>
+<dd>The main app on Google Play. Supports forms and annotations.
+<dt><a href="https://play.google.com/store/apps/details?id=com.artifex.mupdf.viewer.app">MuPDF viewer</a>
+<dd>A slimmed down viewer only variant of the main app.
+<dt><a href="https://play.google.com/store/apps/details?id=com.artifex.mupdf.mini.app">MuPDF mini</a>
+<dd>A minimal code example of a document viewer.
+</dl>
+
+<p>
+The iOS viewer is available on the <a href="https://itunes.apple.com/us/app/mupdf/id482941798">App Store</a>.
+
+<h2>Command Line Tools</h2>
+
+<p>
+The command line tools are all gathered into one umbrella command: mutool.
+
+<p>
+For rendering and converting documents there are three commands available:
+
+<dl>
+<dt><a href="manual-mutool-draw.html">mutool draw</a>
+<dd>This is the more customizable tool, but also has a more difficult set of command line options.
+It is primarily used for rendering a document to image files.
+<dt><a href="manual-mutool-convert.html">mutool convert</a>
+<dd>This tool is used for converting documents into other formats, and is easier to use.
+<dt><a href="manual-mutool-trace.html">mutool trace</a>
+<dd>This is a debugging tool used for printing a trace of the graphics device calls on a page.
+</dl>
+
+<p>
+There are also several tools specifically for working with PDF files:
+
+<dl>
+<dt><a href="manual-mutool-show.html">mutool show</a>
+<dd>A tool for displaying the internal objects in a PDF file.
+<dt><a href="manual-mutool-extract.html">mutool extract</a>
+<dd>Extract images and embedded font resources.
+<dt><a href="manual-mutool-clean.html">mutool clean</a>
+<dd>Rewrite PDF file. Used to fix broken files, or to make a PDF file human editable.
+<dt><a href="manual-mutool-merge.html">mutool merge</a>
+<dd>Merge pages from multiple input files into a new PDF.
+<dt><a href="manual-mutool-create.html">mutool create</a>
+<dd>Create a new PDF file from a text file with graphics commands.
+</dl>
+
+<p>
+And finally, there is a tool for doing anything you can imagine:
+
+<dl>
+<dt><a href="manual-mutool-run.html">mutool run</a>
+<dd>A tool for running Javascript programs with access to the MuPDF library functions.
+</dl>
+
+<h2>Library</h2>
+
+<p>
+The library is written in portable C.
+<!--
+To learn more about the C interface, read the <a href="book/nav.xhtml">MuPDF Explored</a> book.
+The book is also available as a <a href="book.pdf">PDF</a> and <a href="book.epub">EPUB</a> file.
+-->

+<li><a href="api/index.html">MuPDF API reference manual.</a>.
+<li><a href="api/changes.html">Changes in the public API between versions</a>.
+</ul>
+
+<p>
+There is also a Java library, which uses JNI to provide access to the C library.
+The Java classes provide an interface very similar to that available in the
+<a href="manual-mutool-run.html">mutool run</a> command line tool.
+This Java library also powers the Android SDK.
+
+<p>
+If you want to build an application for Android, you have several options. You
+can base it off one of the existing viewers, or build a new app using the Java
+library directly.

+There are several sub commands available, as described below.
+
+.SH DRAW
+mutool draw [options] file [pages]
+.PP
+The draw command will render a document to image files,
+convert to another vector format, or extract the text content.
+.PP
+The supported input document formats are: pdf, xps, cbz, and epub.
+.PP
+The supported output image formats are: pbm, pgm, ppm, pam, png, pwg, pcl and ps.

+.TP
+.B \-p password
+Use the specified password if the file is encrypted.
+.TP
+.B \-o output
+The output format is inferred from the output filename.
+Embed %d in the name to indicate the page number (for example: "page%d.png").
+Printf modifiers are supported, for example "%03d".
+If no output is specified, the output will go to stdout.
+.TP
+.B \-F format
+Enforce a specific output format. Only necessary when outputting to stdout
+since normally the output filename is used to infer the output format.
+.TP
+.B \-R angle

+Fit exactly; ignore the aspect ratio when matching specified width/heights.
+.TP
+.B \-B bandheight
+Render in banded mode with each band no taller than the given height. This uses
+less memory during rendering. Only compatible with pam, pgm, ppm, pnm and png
+output formats. Banded rendering and md5 checksumming may not be used at the
+same time.
+.TP
+.B \-W width
+Page width in points for EPUB layout.

+<h2>
+Image output
+</h2>
+
+<p>
+CBZ (comic book zip) is a multi-page image format.
+
+<p>
+The following single page image formats are also supported: PNG, PNM, PAM, PBM, PKM.
+Each page is written to a separate file.
+
+<p>
+The output options (-O flag) for image formats are:
+
+<dl>
+<dt>rotate=<i>N</i>		<dd>Rotate rendered pages <i>N</i> degrees counter-clockwise.
+<dt>resolution=<i>N</i>		<dd>Set both X and Y resolution in pixels per inch.

+<dt>colorspace=gray/rgb/cmyk	<dd>Render using specified colorspace (if output format supports it).
+<dt>alpha			<dd>Render pages with an alpha channel and transparent background (if output format supports it).
+</dl>
+
+<h2>
+PDF output
+</h2>
+
+<p>
+With PDF output, we will create a new PDF file that matches the visual appearance.
+The PDF output is still a work in progress, so some features may not work.
+
+<p>
+If the input is PDF, the output will have nothing in common except the visual appearance.
+All bookmarks, annotations, forms, etc, will be thrown away. If you want to do a PDF to PDF
+conversion, 'mutool clean' is a better tool to use.

+<dt>garbage=deduplicate		<dd> ... and remove duplicate objects.
+</dl>
+
+<h2>
+SVG output
+</h2>
+
+<p>
+SVG output is a single page format, so we will write one SVG file for each input page.
+
+<p>
+The SVG output options are:
+
+<dl>
+<dt>text=text		<dd> Emit text as <text> elements (inaccurate fonts).

+<dd> Garbage collect unused objects. With compact the cross-reference
+table will also be compacted. With deduplicate duplicate objects
+will also be recombined.
+</dl>
+
+<p>
+A page is created for each input file, with the contents of the

+and image resources:
+
+<pre>
+%%MediaBox 0 0 500 800
+%%Rotate 90
+%%Image Im0 path/to/image.png
+</pre>
+
+<p>
+Font resources can be created by either giving the name of a standard PDF font, or by giving
+the path to a font file. If a third argument is present and either "Greek" or "Cyrillic" the
+font will be encoded using ISO 8859-7 or KOI8-U, respectively.

+%%Font Tm Times-Roman
+%%Font TmG Times-Roman Greek
+%%Font TmC Times-Roman Cyrillic
+%%Font Fn0 path/to/font/file.ttf
+%%Font Fn1 path/to/font/file.ttf Cyrillic
+</pre>
+
+<p>
+CJK fonts can be created by passing a language tag for one of the 4 CID orderings:
+zh-Hant, zh-Hans, ja, or ko (Traditional Chinese, Simplified Chinese, Japanese, Korean).
+The CJK font will use the UTF-16 encoding.
+A font file will not be embedded, so a PDF viewer will use a substitute font.

+
+<p>
+The 'mutool run' command executes a JavaScript program, which has access to most of the features of the MuPDF library.
+The command supports ECMAScript 5 syntax in strict mode.
+All of the MuPDF constructors and functions live in the global object, and the
+command line arguments are accessible from the global 'scriptArgs' object.
+The name of the script is in the global 'scriptPath' variable.
+
+<pre>
+mutool run script.js [ arguments ... ]
+</pre>
+
+<p>
+If invoked without any arguments, it will drop you into an interactive REPL (read-eval-print-loop).
+
+<h2>
+Example scripts

+
+<h2>
+JavaScript Shell
+</h2>
+
+<p>
+Several global functions that are common for command line shells are available:
+
+<dl>
+<dt>gc(report)
+<dd>Run the garbage collector to free up memory. Optionally report statistics on the garbage collection.
+<dt>load(fileName)
+<dd>Load and execute script in 'fileName'.

+They can be used much like arrays, but are much more efficient since they
+only store bytes.
+
+<dl>
+<dt>new Buffer()
+<dd>Create a new empty buffer.
+<dt>readFile(fileName)
+<dd>Create a new buffer with the contents of a file.

+</dl>
+
+<h2>
+Matrices and Rectangles
+</h2>
+
+<p>
+All dimensions are in points unless otherwise specified.
+
+<p>
+Matrices are simply 6-element arrays representing a 3-by-3 transformation matrix as
+
+<pre>
+/ a b 0 \
+| c d 0 |
+\ e f 1 /
+</pre>
+
+<p>
+This matrix is represented in JavaScript as <code>[a,b,c,d,e,f]</code>.
+
+<dl>
+<dt>Identity
+<dd>The identity matrix, short hand for <code>[1,0,0,1,0,0]</code>.
+<dt>Scale(sx, sy)
+<dd>Return a scaling matrix, short hand for <code>[sx,0,0,sy,0,0]</code>.
+<dt>Translate(tx, ty)
+<dd>Return a translation matrix, short hand for <code>[1,0,0,1,tx,ty]</code>.
+<dt>Concat(a, b)
+<dd>Concatenate matrices a and b. Bear in mind that matrix multiplication is not commutative.
+</dl>
+
+<p>
+Rectangles are 4-element arrays, specifying the minimum and maximum corners (typically
+upper left and lower right, in a coordinate space with the origin at the top left with
+descending y): <code>[ulx,uly,lrx,lry]</code>.
+
+<p>
+If the minimum x coordinate is bigger than the maximum x coordinate, MuPDF treats the rectangle
+as infinite in size.
+
+<h2>
+Document and Page
+</h2>
+
+<p>
+MuPDF can open many document types (PDF, XPS, CBZ, EPUB, FB2 and a handful of image formats).
+
+<dl>
+<dt>new Document(fileName)

+</dl>
+
+<h2>
+Pixmap
+</h2>
+
+<p>
+A Pixmap object contains a color raster image (short for pixel map).
+The components in a pixel in the pixmap are all byte values, with the transparency as the last component.
+A pixmap also has a location (x, y) in addition to its size; so that they can easily be used to represent
+tiles of a page.
+
+<dl>
+<dt>new Pixmap(colorspace, bounds, alpha)
+<dd>Create a new pixmap. The pixel data is <b>not</b> initialized; and will contain garbage.

+<dd>Save the pixmap as a PNG. Only works for Gray and RGB images.
+</dl>
+
+<h2>
+DrawDevice
+</h2>
+
+<p>
+The DrawDevice can be used to render to a Pixmap; either by running a Page with it or by calling its methods directly.
+
+<dl>
+<dt>new DrawDevice(transform, pixmap)
+<dd>Create a device for drawing into a pixmap. The pixmap bounds used should match the transformed page bounds,
+or you can adjust them to only draw a part of the page.
+</dl>
+
+<h2>
+DisplayList and DisplayListDevice
+</h2>
+
+<p>
+A display list records all the device calls for playback later.
+If you want to run a page through several devices, or run it multiple times for any other reason,
+recording the page to a display list and replaying the display list may be a performance gain
+since then you can avoid reinterpreting the page each time. Be aware though, that a display list
+will keep all the graphics required in memory, so will increase the amount of memory required.
+
+<dl>
+<dt>new DisplayList(mediabox)
+<dd>Create an empty display list. The mediabox rect has the bounds of the page in points.
+<dt>DisplayList#run(device, transform)
+<dd>Play back the recorded device calls onto the device.
+<dt>DisplayList#toPixmap(transform, colorspace, alpha)
+<dd>Render display list to a pixmap. If alpha is true, it will render to a transparent background, otherwise white.
+<dt>DisplayList#toStructuredText(options)
+<dd>Extract the text in the display list into a StructuredText object.
+The options argument is a comma separated list of flags: preserve-ligatures, preserve-whitespace, and preserve-images.
+<dt>DisplayList#search(needle)
+<dd>Search the display list text for all instances of 'needle', and return an array with rectangles of all matches found.
+<dd>
+</dl>
+
+<dl>
+<dt>new DisplayListDevice(displayList)
+<dd>Create a device for recording onto a display list.
+</dl>
+
+<h2>
+Device
+</h2>
+
+<p>
+All built-in devices have the methods listed below. Any function that accepts a device will also
+accept a JavaScript object with the same methods. Any missing methods are simply ignored, so you
+only need to create methods for the device calls you care about.
+
+<p>
+Many of the methods take graphics objects as arguments: Path, Text, Image and Shade.
+
+<p>
+The stroking state is a dictionary with keys for:
+<dl>
+<dt>startCap, dashCap, endCap:
+<dd>"Butt", "Round", "Square", or "Triangle".
+<dt>lineCap:
+<dd>Set startCap, dashCap, and endCap all at once.
+<dt>lineJoin:
+<dd>"Miter", "Round", "Bevel", or "MiterXPS".
+<dt>lineWidth:
+<dd>Thickness of the line.
+<dt>miterLimit:
+<dd>Maximum ratio of the miter length to line width, before beveling the join instead.
+<dt>dashPhase:
+<dd>Starting offset for dash pattern.
+<dt>dashes:
+<dd>Array of on/off dash lengths.
+</dl>
+
+<p>
+Colors are specified as arrays with the appropriate number of components for the color space.

+</dl>
+
+<dl>
+<dt>Device#beginMask(area, luminosity, backdropColorspace, backdropColor)
+<dt>Device#endMask()
+<dd>Create a soft mask. Any drawing commands between beginMask and endMask are grouped and used as a clip mask.
+If luminosity is true, the mask is derived from the luminosity (grayscale value) of the graphics drawn;
+otherwise the color is ignored completely and the mask is derived from the alpha of the group.
+</dl>
+
+<dl>
+<dt>Device#popClip()
+<dd>Pop the clip mask installed by the last clipping operation.
+</dl>
+
+<dl>
+<dt>Device#beginGroup(area, isolated, knockout, blendmode, alpha)
+<dt>Device#endGroup()
+<dd>Push/pop a transparency blending group. Blendmode is one of the standard PDF blend modes: "Normal", "Multiply", "Screen", etc. See the PDF reference for details on isolated and knockout.

+<dl>
+<dt>new Text()
+<dd>Create a new empty text object.
+<dt>Text#showGlyph(font, transform, glyph, unicode, wmode)
+<dd>Add a glyph to the text object. Transform is the text matrix, specifying font size and glyph location. For example: <code>[size,0,0,-size,x,y]</code>.
+Glyph and unicode may be -1 for n-to-m cluster mappings.
+For example, the "fi" ligature would be added in two steps: first the glyph for the 'fi' ligature and the unicode value for 'f';
+then glyph -1 and the unicode value for 'i'.
+WMode is 0 for horizontal writing, and 1 for vertical writing.
+<dt>Text#showString(font, transform, string)

+The output formats and options supported are the same as in the
+<a href="manual-mutool-convert.html">mutool convert</a> command.
+
+<h2>
+PDFDocument and PDFObject
+</h2>
+
+<p>
+With MuPDF it is also possible to create, edit and manipulate PDF documents
+using low level access to the objects and streams contained in a PDF file.
+A PDFDocument object is also a Document object. You can test a Document object
+to see if it is safe to use as a PDFDocument by calling document.isPDF().
+
+<dl>
+<dt>new PDFDocument()
+<dd>Create a new empty PDF document.
+<dt>new PDFDocument(fileName)
+<dd>Load a PDF document from file.
+<dt>PDFDocument#save(fileName, options)

+</dl>
+
+<h3>
+PDF Object Access
+</h3>
+
+<p>
+A PDF document contains objects, similar to those in JavaScript: arrays, dictionaries, strings, booleans, and numbers.
+At the root of the PDF document is the trailer object; which contains pointers to the meta data dictionary and the
+catalog object which contains the pages and other information.
+
+<p>
+Pointers in PDF are also called indirect references,
+and are of the form "32 0 R" (where 32 is the object number, 0 is the generation, and R is magic syntax).
+All functions in MuPDF dereference indirect references automatically.
+
+<p>
+PDF has two types of strings: /Names and (Strings). All dictionary keys are names.
+
+<p>
+Some dictionaries in PDF also have attached binary data. These are called streams, and may be compressed.
+
+<dl>
+<dt>PDFDocument#getTrailer()
+<dd>The trailer dictionary. This contains indirect references to the Root and Info dictionaries.
+<dt>PDFDocument#countObjects()
+<dd>Return the number of objects in the PDF. Object number 0 is reserved, and may not be used for anything.
+<dt>PDFDocument#createObject()
+<dd>Allocate a new numbered object in the PDF, and return an indirect reference to it.
+The object itself is uninitialized.
+<dt>PDFDocument#deleteObject(obj)
+<dd>Delete the object referred to by the indirect reference.
+</dl>
+
+<p>
+PDFObjects are always bound to the document that created them.
+Do NOT mix and match objects from one document with another document!
+
+<dl>
+<dt>PDFDocument#addObject(obj)
+<dd>Add 'obj' to the PDF as a numbered object, and return an indirect reference to it.
+<dt>PDFDocument#addStream(buffer, object)
+<dd>Create a stream object with the contents of 'buffer', add it to the PDF, and return an indirect reference to it. If object is defined, it will be used as the stream object dictionary.
+<dt>PDFDocument#addRawStream(buffer, object)
+<dd>Create a stream object with the contents of 'buffer', add it to the PDF, and return an indirect reference to it.
+If object is defined, it will be used as the stream object dictionary.
+The buffer must contain already compressed data that matches the Filter and DecodeParms.

+<dt>PDFDocument#newInteger(number)
+<dt>PDFDocument#newReal(number)
+<dt>PDFDocument#newString(string)

+<dt>PDFDocument#newIndirect(objectNumber, generation)
+<dt>PDFDocument#newArray()
+<dt>PDFDocument#newDictionary()
+</dl>
+
+<p>
+The following functions can be used to copy objects from one document to another:
+
+<dl>
+<dt>PDFDocument#graftObject(object)
+<dd>Deep copy an object into the destination document. This function will not remember previously
+copied objects.
+If you are copying several objects from the same source document using multiple calls, you should
+use a graft map instead.
+<dt>PDFDocument#newGraftMap()
+<dd>Create a graft map for the source document, so that objects that have already been copied can be found again.
+<dt>PDFGraftMap#graftObject(object)
+<dd>Use the graft map to copy objects, with the ability to remember previously copied objects.
+</dl>
+
+<p>
+All functions that take PDF objects, do automatic translation between JavaScript objects
+and PDF objects using a few basic rules. Null, booleans, and numbers are translated directly.
+JavaScript strings are translated to PDF names, unless they are surrounded by parentheses:
+"Foo" becomes the PDF name /Foo and "(Foo)" becomes the PDF string (Foo).
+
+<p>
+Arrays and dictionaries are recursively translated to PDF arrays and dictionaries.
+Be aware of cycles though! The translation does NOT cope with cyclic references!
+
+<p>
+The translation goes both ways: PDF dictionaries and arrays can be accessed similarly
+to JavaScript objects and arrays by getting and setting their properties.
+
+<dl>
+<dt>PDFObject#get(key or index)
+<dt>PDFObject#put(key or index, value)
+<dt>PDFObject#delete(key or index)
+<dd>Access dictionaries and arrays. Dictionaries and arrays can also be accessed using normal property syntax: obj.Foo = 42; delete obj.Foo; x = obj[5].
+<dt>PDFObject#resolve()
+<dd>If the object is an indirect reference, return the object it points to; otherwise return the object itself.
+<dt>PDFObject#isArray()
+<dt>PDFObject#isDictionary()
+<dt>PDFObject#forEach(function(key,value){...})
+<dd>Iterate over all the entries in a dictionary or array and call fun for each key-value pair.
+<dt>PDFObject#length
+<dd>Length of the array.
+<dt>PDFObject#push(item)
+<dd>Append item to the end of the array.
+</dl>
+
+<p>
+The only way to access a stream is via an indirect object, since all streams
+are numbered objects.
+
+<dl>
+<dt>PDFObject#isIndirect()
+<dd>Is the object an indirect reference.
+<dt>PDFObject#asIndirect()
+<dd>Return the object number the indirect reference points to.
+<dt>PDFObject#isStream()
+<dd>True if the object is an indirect reference pointing to a stream.
+<dt>PDFObject#readStream()
+<dd>Read the contents of the stream object into a Buffer.
+<dt>PDFObject#readRawStream()
+<dd>Read the raw, uncompressed, contents of the stream object into a Buffer.
+<dt>PDFObject#writeObject(obj)
+<dd>Update the object the indirect reference points to.
+<dt>PDFObject#writeStream(buffer)
+<dd>Update the contents of the stream the indirect reference points to.
+This will update the Length, Filter and DecodeParms automatically.
+<dt>PDFObject#writeRawStream(buffer)
+<dd>Update the contents of the stream the indirect reference points to.
+The buffer must contain already compressed data that matches the Filter and DecodeParms.
+This will update the Length automatically, but leave the Filter and DecodeParms untouched.
+</dl>
+
+<p>
+Primitive PDF objects such as booleans, names, and numbers can usually be treated like JavaScript values.
+When that is not sufficient use these functions:
+
+<dl>
+<dt>PDFObject#isNull()
+<dd>Is the object the 'null' object?
+<dt>PDFObject#isBoolean()
+<dd>Is the object a boolean?
+<dt>PDFObject#asBoolean()
+<dd>Get the boolean primitive value.
+<dt>PDFObject#isNumber()
+<dd>Is the object a number?
+<dt>PDFObject#asNumber()
+<dd>Get the number primitive value.
+<dt>PDFObject#isName()
+<dd>Is the object a name?
+<dt>PDFObject#asName()
+<dd>Get the name as a string.
+<dt>PDFObject#isString()
+<dd>Is the object a string?
+<dt>PDFObject#asString()
+<dd>Convert a "text string" to a javascript unicode string.
+<dt>PDFObject#asByteString()
+<dd>Convert a string to an array of byte values.
+</dl>
+
+<h3>
+PDF Page Access
+</h3>
+
+<p>
+All page objects are structured into a page tree, which defines the order the pages appear in.
+
+<dl>
+<dt>PDFDocument#countPages()
+<dd>Number of pages in the document.
+<dt>PDFDocument#findPage(number)
+<dd>Return the page object for a page number. The first page is number zero.
+<dt>PDFDocument#deletePage(number)
+<dd>Delete the numbered page.
+<dt>PDFDocument#insertPage(at, page)
+<dd>Insert the page object in the page tree at the location. If 'at' is -1, at the end of the document.
+</dl>
+
+<p>
+Pages consist of a content stream, and a resource dictionary containing all of the fonts and images used.
+
+<dl>
+<dt>PDFDocument#addPage(mediabox, rotate, resources, contents)
+<dd>Create a new page object. Note: this function does NOT add it to the page tree.
+<dt>PDFDocument#addSimpleFont(font, encoding)
+<dd>Create a PDF object from the Font object as a simple font.
+Encoding is either "Latin" (CP-1252), "Greek" (ISO-8859-7), or "Cyrillic" (KOI-8U).
+The default is "Latin".
+<dt>PDFDocument#addCJKFont(font, language, wmode, style)
+<dd>Create a PDF object from the Font object as a UTF-16 encoded CID font for the given
+language ("zh-Hant", "zh-Hans", "ko", or "ja"),

+and style ("serif" or "sans-serif").
+<dt>PDFDocument#addFont(font)
+<dd>Create a PDF object from the Font object as an Identity-H encoded CID font.
+<dt>PDFDocument#addImage(image)
+<dd>Create a PDF object from the Image object.
+<dt>PDFDocument#loadImage(obj)
+<dd>Load an Image from a PDF object (typically an indirect reference to an image resource).
+</dl>
+
+<h3>
+PDF Annotations (WORK IN PROGRESS!)
+</h3>
+
+<dl>
+<dt>PDFPage#createAnnotation(type)
+<dd>Create a new blank annotation of a given type.
+The type must be one of the annotation subtypes listed in the PDF reference.

+<p>
+The 'mutool trace' command prints a trace of device calls needed to render a page.
+
+<pre>
+mutool trace [options] input [pages]
+</pre>
+
+<p>
+The command line options are:
+
+<dl>
+<dt><i>input</i>
+	<dd>Input file name.
+	The input can be any of the document formats supported by MuPDF: PDF, XPS, CBZ, unprotected EPUB, FB2, etc.
+<dt>[pages]
+	<dd>Comma separated list of page ranges. The first page is "1", and the last page is "N". The default is "1-N".
+<dt>-p <i>password</i>
+	<dd>Password to use for password protected PDF documents.
+</dl>
+
+<dl>
+<dt>-W <i>width</i>
+	<dd>Page width in points for EPUB layout.
+<dt>-H <i>height</i>
+	<dd>Page height in points for EPUB layout.
+<dt>-S <i>font-size</i>
+	<dd>Font size in points for EPUB layout.
+<dt>-U <i>stylesheet.css</i>
+	<dd>File name of user style sheet for EPUB layout.
+<dt>-X
+	<dd>Disable document styles for EPUB layout.
+</dl>
+
+<dl>
+<dt>-d
+	<dd>Use display list. Run the page to a display list first, then trace running the display list.
+</dl>
+
+<p>
+The trace takes the form of an XML document, with the root element being the document,
+its children each page, and one page child element for each device call on that page.
+
+<p>
+An example trace:
+
+<pre>
+&lt;document filename="hello.pdf"&gt;

+	The store can be seen as a dictionary that maps keys to fz_storable
+	values. In order to allow keys of different types to be stored, we
+	have a structure full of functions for each key 'type'; this
+	fz_store_type pointer is stored with each key, and tells the store
+	how to perform certain operations (like taking/dropping a reference,
+	comparing two keys, outputting details for debugging etc).
+
+	The store uses a hash table internally for speed where possible. In
+	order for this to work, we need a mechanism for turning a generic
+	'key' into 'a hashable string'. For this purpose the type structure
+	contains a make_hash_key function pointer that maps from a void *
+	to a fz_store_hash structure. If make_hash_key function returns 0,
+	then the key is determined not to be hashable, and the value is
+	not stored in the hash table.
+
+	Some objects can be used both as values within the store, and as a
+	component of keys within the store. We refer to these objects as
+	"key storable" objects. In this case, we need to take additional
+	care to ensure that we do not end up keeping an item within the
+	store, purely because its value is referred to by another key in
+	the store.
+
+	An example of this are fz_images in PDF files. Each fz_image is
+	placed into the	store to enable it to be easily reused. When the
+	image is rendered, a pixmap is generated from the image, and the
+	pixmap is placed into the store so it can be reused on subsequent
+	renders. The image forms part of the key for the pixmap.
+
+	When we close the pdf document (and any associated pages/display
+	lists etc), we drop the images from the store. This may leave us
+	in the position of the images having non-zero reference counts
+	purely because they are used as part of the keys for the pixmaps.
+
+	We therefore use special reference counting functions to keep
+	track of these "key storable" items, and hence store the number of
+	references to these items that are used in keys.
+
+	When the number of references to an object == the number of
+	references to an object from keys in the store, we know that we can
+	remove all the items which have that object as part of the key.
+	This is done by running a pass over the store, 'reaping' those
+	items.
+
+	Reap passes are slower than we would like as they touch every
+	item in the store. We therefore provide a way to 'batch' such
+	reap passes together, using fz_defer_reap_start/fz_defer_reap_end
+	to bracket a region in which many may be triggered.
