By contrast, +the GNU General Public License is 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. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + 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. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + 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 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. Use with the GNU Affero General Public License. + + 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 Affero 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 special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU 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 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 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 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 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 General Public License for more details. + + You should have received a copy of the GNU 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 the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + <program> Copyright (C) <year> <name of author> + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + 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 GPL, see +<http://www.gnu.org/licenses/>. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library.

Additional Definitions. + + As used herein, "this License" refers to version 3 of the GNU Lesser +General Public License, and the "GNU GPL" refers to version 3 of the GNU +General Public License. + + "The Library" refers to a covered work governed by this License, +other than an Application or a Combined Work as defined below. + + An "Application" is any work that makes use of an interface provided +by the Library, but which is not otherwise based on the Library. +Defining a subclass of a class defined by the Library is deemed a mode +of using an interface provided by the Library. + + A "Combined Work" is a work produced by combining or linking an +Application with the Library. The particular version of the Library +with which the Combined Work was made is also called the "Linked +Version". + + The "Minimal Corresponding Source" for a Combined Work means the +Corresponding Source for the Combined Work, excluding any source code +for portions of the Combined Work that, considered in isolation, are +based on the Application, and not on the Linked Version. + + The "Corresponding Application Code" for a Combined Work means the +object code and/or source code for the Application, including any data +and utility programs needed for reproducing the Combined Work from the +Application, but excluding the System Libraries of the Combined Work. + + 1. Exception to Section 3 of the GNU GPL. + + You may convey a covered work under sections 3 and 4 of this License +without being bound by section 3 of the GNU GPL. + + 2. Conveying Modified Versions. + + If you modify a copy of the Library, and, in your modifications, a +facility refers to a function or data to be supplied by an Application +that uses the facility (other than as an argument passed when the +facility is invoked), then you may convey a copy of the modified +version: + + a) under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the + function or data, the facility still operates, and performs + whatever part of its purpose remains meaningful, or + + b) under the GNU GPL, with none of the additional permissions of + this License applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + + The object code form of an Application may incorporate material from +a header file that is part of the Library. You may convey such object +code under terms of your choice, provided that, if the incorporated +material is not limited to numerical parameters, data structure +layouts and accessors, or small macros, inline functions and templates +(ten or fewer lines in length), you do both of the following: + + a) Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the object code with a copy of the GNU GPL and this license + document. + + 4. Combined Works. + + You may convey a Combined Work under terms of your choice that, +taken together, effectively do not restrict modification of the +portions of the Library contained in the Combined Work and reverse +engineering for debugging such modifications, if you also do each of +the following: + + a) Give prominent notice with each copy of the Combined Work that + the Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the Combined Work with a copy of the GNU GPL and this license + document. + + c) For a Combined Work that displays copyright notices during + execution, include the copyright notice for the Library among + these notices, as well as a reference directing the user to the + copies of the GNU GPL and this license document. + + d) Do one of the following: + + 0) Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form + suitable for, and under terms that permit, the user to + recombine or relink the Application with a modified version of + the Linked Version to produce a modified Combined Work, in the + manner specified by section 6 of the GNU GPL for conveying + Corresponding Source. + + 1) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (a) uses at run time + a copy of the Library already present on the user's computer + system, and (b) will operate properly with a modified version + of the Library that is interface-compatible with the Linked + Version. + + e) Provide Installation Information, but only if you would otherwise + be required to provide such information under section 6 of the + GNU GPL, and only to the extent that such information is + necessary to install and execute a modified version of the + Combined Work produced by recombining or relinking the + Application with a modified version of the Linked Version. (If + you use option 4d0, the Installation Information must accompany + the Minimal Corresponding Source and Corresponding Application + Code. If you use option 4d1, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL + for conveying Corresponding Source.) + + 5. Combined Libraries. + + You may place library facilities that are a work based on the +Library side by side in a single library together with other library +facilities that are not Applications and are not covered by this +License, and convey such a combined library under terms of your +choice, if you do both of the following: + + a) Accompany the combined library with a copy of the same work based + on the Library, uncombined with any other library facilities, + conveyed under the terms of this License. + + b) Give prominent notice with the combined library that part of it + is a work based on the Library, and explaining where to find the + accompanying uncombined form of the same work. + + 6. Revised Versions of the GNU Lesser General Public License. + + The Free Software Foundation may publish revised and/or new versions +of the GNU Lesser 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 +Library as you received it specifies that a certain numbered version +of the GNU Lesser General Public License "or any later version" +applies to it, you have the option of following the terms and +conditions either of that published version or of any later version +published by the Free Software Foundation. If the Library as you +received it does not specify a version number of the GNU Lesser +General Public License, you may choose any version of the GNU Lesser +General Public License ever published by the Free Software Foundation. + + If the Library as you received it specifies that a proxy can decide +whether future versions of the GNU Lesser General Public License shall +apply, that proxy's public statement of acceptance of any version is +permanent authorization for you to choose that version for the +Library. diff --git a/dviware/dvipng/COPYING.gd b/dviware/dvipng/COPYING.gd new file mode 100644 index 0000000000..db6a326580 --- /dev/null +++ b/dviware/dvipng/COPYING.gd @@ -0,0 +1,54 @@ +The below is the copyright notice of the gd library. +---------------------------------------------------- + +Portions copyright 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, +2002 by Cold Spring Harbor Laboratory.

In any case, + the latest version of the library installs using 'autoconf' so it + should not be difficult for you to install it from source, and then + proceed with installing dvipng. + + * The path-searching library kpathsea + + Kpathsea is most likely included in your LaTeX installation, but it + may happen that ./configure does not find it; see below. If you do + not have it, download it from <http://www.ctan.org> and compile it. + I have no experience with this, so I cannot help much here. + + * The font-rendering library FreeType 2 + + While not strictly necessary, a recent FreeType 2 is recommended + since dvipng currently will produce better-quality images when this + library is available. To take advantage of this, you should have + at least FreeType 2.1.9. + + FreeType 2 will enable direct support for PostScript and TrueType + fonts, so that dvipng will not need to generate bitmapped variants + on disk of the TeX fonts since modern TeX distributions include + PostScript versions of them. Then, you can render images at + different (and unusual) resolutions without cluttering the disk + with lots of bitmapped fonts. + + Finally, it will enable subfont support in dvipng. That is, if you + want to render CJK-LaTeX characters, you must have FreeType 2 + installed. + + * libpng and libz + + To be able to compress and write PNG files to disk, dvipng (or + really libgd) uses libpng which in turn uses libz. These should be + available on any modern system, if not, download them and install + them. + + * The 'texinfo' package + + This is needed for building the documentation. + +Configure +========= + +The first step is to configure the source code, telling it where various +files will be. To do so, run + + ./configure OPTIONS + + (Note: if you have fetched dvipng from CVS rather than a regular +release, you will have to first generate './configure' by running +'autoconf' 2.53 or later.) + + On many machines, you will not need to specify any options, but if +'configure' cannot determine something on its own, you'll need to help +it out. For a list of the options type + + ./configure --help + + On some machines, the libraries will be installed in directories that +are not in the linker's search path. This will generate an error when +running './configure', indicating that it cannot find libgd or +libkpathsea (most likely). You then need to specify the path to the +respective library's object files. They are typically called e.g., +'libgd.a' or 'libgd.so'. If they are located in e.g., '/sw/local/lib', +do + + ./configure LDFLAGS=-L/sw/local/lib + + If the library is available as a shared object file ('.so'), the +runtime linker may also need to be told where to find the library, then +use + + ./configure LDFLAGS='-L/sw/local/lib -R/sw/local/lib' + + When either of these is necessary, it is likely that the C header +files are also installed in directories that are not in the C +preprocessor's search path. This will also generate an error when +running './configure', indicating that it cannot find e.g., 'gd.h' or +'kpathsea.h' (most likely). You then need to specify the path to the +respective library's C header files. If they are located in e.g., +'/sw/local/include', do + + ./configure CPPFLAGS=-I/sw/local/include + + On my SUN Solaris workstation, I had to combine this into + + ./configure CPPFLAGS='-I/sw/local/include -I/sw/tex/teTeX/1.0/include'\ + LDFLAGS='-L/sw/local/lib -R/sw/local/lib -L/sw/tex/teTeX/1.0/lib/' + +where the backslash denotes a continuation of the line. + +Build/install +============= + +Once 'configure' has been run, simply enter + + make + +at the prompt to compile the C code, and build the documentation files. +To install the files into the locations chosen earlier, type + + make install + +You may need special privileges to install, e.g., if you are installing +into system directories. + +Installation outside the texmf tree +=================================== + +In some cases, a dvipng binary installed outside the texmf tree will not +be able to find virtual fonts, or the PostScript font maps (normally +used by dvips). This may be because _only_ $SELFAUTOLOC, $SELFAUTODIR, +and $SELFAUTOPARENT are used in the texmf tree configuration file +'texmf.cnf'. If so, give the switch '--enable-selfauto-set' to +'./configure'. This will make dvipng adjust these three internally so +that kpathsea thinks that dvipng _is_ installed in the texmf tree. + +Installation for non-privileged users +===================================== + +Often people without system administration privileges want to install +software for their private use. In that case you need to specify more +options to the 'configure' script, usually this is done by using the +'--prefix' option to the 'configure' script, and let it point to the +personal home directory. In that way, resulting binaries will be +installed under the 'bin' subdirectory of your home directory, manual +pages under 'man' and so on. That way, it is reasonably easy to +maintain a bunch of additional packages, since the prefix argument is +supported by most 'configure' scripts. + + You'll have to add something like '/home/myself/bin' to your 'PATH' +shell variable, if it isn't there already, and similarly set the +'INFOPATH' and 'MANPATH' variables to be able to access the +documentation. + +Copying +======= + +This program is released under the GNU Lesser General Public License +version 3, see the COPYING file in the dvipng distribution or +<http://www.gnu.org/licenses/>. + + Copyright (C) 2002-2015 Jan-AAke Larsson diff --git a/dviware/dvipng/Makefile.in b/dviware/dvipng/Makefile.in new file mode 100644 index 0000000000..d57b925324 --- /dev/null +++ b/dviware/dvipng/Makefile.in @@ -0,0 +1,170 @@ +# Makefile is generated by 'configure' from Makefile.in + +#************************************************************************ +# +# Part of the dvipng distribution +# +# This program is free software: you can redistribute it and/or modify +# it under the terms of the GNU Lesser 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.

The primary target is the +preview-latex (X)Emacs package, a package to preview formulas from +within (X)Emacs.

It is a very fast bitmap-rendering code for DVI files, + which makes it suitable for generating large amounts of images + on-the-fly, as needed in preview-latex, WeBWorK and others. + + * It does not read the postamble, so it can be started before TeX + finishes. There is a '--follow' switch that makes dvipng wait at + end-of-file for further output, unless it finds the POST marker + that indicates the end of the DVI. + + * Interactive query of options. dvipng can read options + interactively through stdin, and all options are usable. It is + even possible to change the input file through this interface. + + * Supports PK, VF, PostScript Type1, and TrueType fonts, subfonts + (i.e., as used in CJK-LaTeX), color specials, and inclusion of + PostScript, PNG, JPEG or GIF images. + + * and more... + +Installation +============ + +Read 'INSTALL', included in the distribution. + +Usage +===== + +To use dvipng at its simplest, simply type + + dvipng foo + +where 'foo.dvi' is the output of TeX that you want to convert to PNG +format. If there are four pages in 'foo.dvi', those pages will be +output as 'foo1.png', 'foo2.png', 'foo3.png', and 'foo4.png', +respectively. + + Many options are available (see the info manual).

This switch makes dvipng wait at end-of-file for further +output, unless it finds the \s-1POST\s0 marker that indicates the end of the +\&\s-1DVI.\s0 This is similar to \fBtail \-f\fR but for DVI-to-PNG conversion. +.IP "\fB\-\-freetype*\fR" 4 +.IX Item "--freetype*" +Enable/disable FreeType font rendering (default on). This option is +available if the FreeType2 font library was present at compilation time. +If this is the case, dvipng will have direct support for PostScript +Type1 and TrueType fonts internally, rather than using \fBgsftopk\fR +for rendering the fonts.

Use +\&\fImode\fR as the Metafont device name for the \s-1PK\s0 fonts (both for path +searching and font generation). This needs to be augmented with the base +device resolution, given with the \fB\-\-bdpi\fR option.

The +\&\fB\-\-nogssafer\fR option runs GhostScript without \fB\-dSAFER\fR. The +\&\fB\-dSAFER\fR option in Ghostscript disables PostScript operators such +as deletefile, to prevent possibly malicious PostScript programs from +having any effect. +.IP "\fB\-\-norawps*\fR" 4 +.IX Item "--norawps*" +Some packages generate raw PostScript specials, even non-rendering such +specials. This switch turns off the internal call to GhostScript +intended to display these raw PostScript specials. \fB\-\-norawps0\fR +turns the call back on. +.IP "\fB\-o\fR \fIname\fR" 4 +.IX Item "-o name" +Send output to the file \fIname\fR. A single occurrence of \fB\f(CB%d\fB\fR or +\&\fB\f(CB%01d\fB\fR, ..., \fB\f(CB%09d\fB\fR will be exchanged for the physical +page number (this can be changed, see the \fB\-\-dvinum\fR switch). The +default output filename is \fIfile\fR\fB\f(CB%d\fB.png\fR where the input \s-1DVI\s0 +file was \fIfile\fR\fB.dvi\fR. +.IP "\fB\-O\fR \fIx\-offset\fR\fB,\fR\fIy\-offset\fR" 4 +.IX Item "-O x-offset,y-offset" +Move the origin by \fIx\-offset\fR,\fIy\-offset\fR, a comma-separated +pair of dimensions such as \fB.1in,\-.3cm\fR. +The origin of the page is shifted from the default position +(of one inch down, one inch to the right from the upper left corner of +the paper) by this amount. +.IP "\fB\-p [=]\fR\fInum\fR" 4 +.IX Item "-p [=]num" +The first page printed will be the first one numbered \fInum\fR. Default +is the first page in the document. If \fInum\fR is prefixed by an +equals sign, then it (and the argument to the \fB\-l\fR option, if +specified) is treated as a physical (absolute) page number, rather than +a value to compare with the TeX \fB\ecount0\fR values stored in the +\&\s-1DVI\s0 file. Thus, using \fB\-p =3\fR will start with the third page of +the document, no matter what the pages are actually numbered. +.IP "\fB\-\-palette*\fR" 4 +.IX Item "--palette*" +When an external image is included, \fBdvipng\fR will automatically +switch to truecolor mode, to avoid unnecessary delay and quality +reduction, and enable the \s-1EPS\s0 translator to draw on a transparent +background and outside of the boundingbox. This switch will force +palette (256\-color) output and make \fBdvipng\fR revert to opaque +clipped image inclusion. This will also override the \fB\-\-truecolor\fR +switch if present. +.IP "\fB\-\-picky*\fR" 4 +.IX Item "--picky*" +No images are output when a warning occurs. Normally, dvipng will +output an image in spite of a warning, but there may be something +missing in this image. One reason to use this option would be if you +have a more complete but slower fallback converter. Mainly, this is +useful for failed figure inclusion and unknown \especial occurrences, +but warnings will also occur for missing or unknown color specs and +missing \s-1PK\s0 fonts. +.IP "\fB\-\-png*\fR" 4 +.IX Item "--png*" +The images are output in the \s-1PNG\s0 format. This is the default for the +\&\fBdvipng\fR binary. See also the \fB\-\-gif\fR option. +.IP "\fB\-pp\fR \fIfirstpage\fR\fB\-\fR\fIlastpage\fR" 4 +.IX Item "-pp firstpage-lastpage" +Print pages \fIfirstpage\fR through \fIlastpage\fR; but not quite +equivalent to \fB\-p\fR \fIfirstpage\fR \fB\-l\fR \fIlastpage\fR. For example, +when rendering a book, there may be several instances of a page in the +\&\s-1DVI\s0 file (one in \f(CW\*(C`\efrontmatter\*(C'\fR, one in \f(CW\*(C`\emainmatter\*(C'\fR, and one +in \f(CW\*(C`\ebackmatter\*(C'\fR). In case of several pages matching, \fB\-pp\fR +\&\fIfirstpage\fR\fB\-\fR\fIlastpage\fR will render \fIall\fR pages that +matches the specified range, while \fB\-p\fR \fIfirstpage\fR \fB\-l\fR +\&\fIlastpage\fR will render the pages from the \fIfirst\fR occurrence +of \fIfirstpage\fR to the \fIfirst\fR occurrence of \fIlastpage\fR. +This is the (undocumented) behaviour of dvips. In dvipng you can give +both kinds of options, in which case you get all pages that matches the +range in \fB\-pp\fR between the pages from \fB\-p\fR to \fB\-l\fR. Also +multiple \fB\-pp\fR options accumulate, unlike \fB\-p\fR and \fB\-l\fR. +The \fB\-\fR separator can also be \fB:\fR. Note that \fB\-pp \-1\fR +will be interpreted as \*(L"all pages up to and including 1\*(R", if you want a +page numbered \-1 (only the table of contents, say) put \fB\-pp \-1\-\-1\fR, +or more readable, \fB\-pp \-1:\-1\fR. +.IP "\fB\-q*\fR" 4 +.IX Item "-q*" +Run quietly. Don't chatter about pages converted, etc. to standard +output; report no warnings (only errors) to standard error. +.IP "\fB\-Q\fR \fInum\fR" 4 +.IX Item "-Q num" +Set the quality to \fInum\fR. That is, choose the number of antialiasing +levels for bitmapped fonts (\s-1PK\s0), to be +\&\fInum\fR*\fInum\fR+1. The default value is 4 which gives 17 levels of +antialiasing for antialiased fonts from these two. If FreeType is +available, its rendering is unaffected by this option. +.IP "\fB\-r*\fR" 4 +.IX Item "-r*" +Toggle output of pages in reverse/forward order. By default, the first +page in the \s-1DVI\s0 is output first. +.IP "\fB\-\-strict*\fR" 4 +.IX Item "--strict*" +The program exits when a warning occurs. Normally, dvipng will output +an image in spite of a warning, but there may be something missing in +this image. One reason to use this option would be if you have a more +complete but slower fallback converter. See the \fB\-\-picky\fR option +above for a list of when warnings occur. +.IP "\fB\-T\fR \fIimage_size\fR" 4 +.IX Item "-T image_size" +Set the image size to \fIimage_size\fR which can be either of +\&\fBbbox\fR, \fBtight\fR, or a comma-separated pair of dimensions +\&\fIhsize\fR,\fIvsize\fR such as \fB.1in,.3cm\fR. The default is +\&\fBbbox\fR which produces a \s-1PNG\s0 that includes all ink put on the page +and in addition the \s-1DVI\s0 origin, located 1in from the top and 1in from +the left edge of the paper. This usually gives whitespace above and to +the left in the produced image. The value \fBtight\fR will make dvipng +only include all ink put on the page, producing neat images. +.IP "\fB\-\-truecolor*\fR" 4 +.IX Item "--truecolor*" +This will make \fBdvipng\fR generate truecolor output. Note that +truecolor output is automatic if you include an external image in your +\&\s-1DVI,\s0 e.g., via a PostScript special (i.e., the \fBgraphics\fR or +\&\fBgraphicx\fR package). This switch is overridden by the +\&\fB\-\-palette\fR switch. +.IP "\fB\-v*\fR" 4 +.IX Item "-v*" +Enable verbose operation. This will currently indicate what fonts is +used, in addition to the usual output. +.IP "\fB\-\-width*\fR" 4 +.IX Item "--width*" +Report the width of the image. See also \fB\-\-height\fR and +\&\fB\-\-depth\fR. +.IP "\fB\-x\fR \fInum\fR" 4 +.IX Item "-x num" +This option is deprecated; it should not be used. It is much better to +select the output resolution directly with the \fB\-D\fR option. This +option sets the magnification ratio to \fInum\fR/1000 and +overrides the magnification specified in the \s-1DVI\s0 file. Must be between +10 and 100000. It is recommended that you use standard magstep values +(1095, 1200, 1440, 1728, 2074, 2488, 2986, and so on) to help reduce the +total number of \s-1PK\s0 files generated. \fInum\fR may be a real number, not +an integer, for increased precision. +.IP "\fB\-z\fR \fInum\fR" 4 +.IX Item "-z num" +Set the \s-1PNG\s0 compression level to \fInum\fR. This option is enabled if +your \fBlibgd\fR is new enough. The default compression level is 1, +which selects maximum speed at the price of slightly larger PNGs. For an +older \fBlibgd\fR, the hard-soldered value 5 is used. The include file +\&\fBpng.h\fR says +\&\*(L"Currently, valid values range from 0 \- 9, corresponding directly to +the zlib compression levels 0 \- 9 (0 \- no compression, 9 \- \*(R"maximal\*(L" +compression).

If there are four pages in @file{foo.dvi}, those pages will +be output as @file{foo1.png}, @file{foo2.png}, @file{foo3.png}, and +@file{foo4.png}, respectively. + +If you have enabled the PostScript font support (via FreeType), +fonts will be rendered as they are needed. Otherwise, dvipng will use +bitmapped (PK) fonts, and if you use PK fonts that have not been used on +your system before, they may be automatically generated; this process +can take a few minutes, so progress reports appear by default. The next +time the same font is used, it will have been saved on disk, so +rendering will go much faster. (If dvipng tries to endlessly generate +the same fonts over and over again, something is wrong. @xref{Unable to +generate fonts,,, kpathsea, Kpathsea}.) + +Many options are available (see the next section).

Rendering raw PostScript +specials is done on top of the page by including a transparent image +generated by the @samp{pngalpha} device in GhostScript (automatically +selecting @samp{truecolor} mode in dvipng). + +Included PostScript headers are respected, and if the header +@samp{tex.pro} is included, dvipng also throws in @samp{color.pro} and +@samp{special.pro}. The package @samp{xcolor} includes its own headers +with color names, and this is not only kept as a PostScript header, but +is also read and interpreted by dvipng itself. An attempt is also made +to respect the PGF header. The non-rendering specials from +@samp{hyperref} are handled via some heuristics and do not give an +error. + +Really rendering and moving things with raw PostScript specials is more +troublesome. The \rotatebox macro serves as a good example. The dvips +driver of the graphicx package surrounds DVI glyphs with PostScript code +so that after conversion by dvips, the glyphs (now themselves in +PostScript) will be rotated in the desired way. dvipng does not handle +this, at present. An attempt has been made to handle the rendering +specials output by PGF (tikz), and also PSTricks. Some things work, but +others do not. This is especially clear when mixing PostScript and DVI +rendering commands such as glyphs. dvipng cannot at present detect if +PostScript code moves @samp{currentpoint} or rotates the frame since +GhostScript does not return such information. A recommendation would be +to produce images from these packages as EPS files and include them into +your document in the standard manner. + +Another way to handle this would be to use a slower fallback (with dvips +and gs, for example). If you want to disable raw PostScript handling in +dvipng, use the switch @samp{--norawps}. This switch turns off the +internal call to GhostScript intended to display these raw PostScript +specials. Further, when dvipng encounters raw PostScript and the gs call +is turned off, it gives a warning. It is now possible to use the switch +@samp{--picky} to disable page rendering of pages with warnings, and use +the slower fallback for these pages. + +@node Color +@chapter Color + +To support color, dvipng recognizes a certain set of specials as +generated by the @samp{color} and @samp{xcolor} style files.

The +by-value spec starts with the name of a color model (one of @samp{rgb}, +@samp{hsb}, @samp{cmy}, @samp{cmyk}, or @samp{gray}) followed by the +appropriate number of parameters. Thus, the color specification +@samp{rgb 0.3 0.4 0.5} would correspond to the color that is @samp{0.3 +0.4 0.5} in its red, blue and green values. The color model used +internally in dvipng is @samp{RGB} (discretized to 256 levels), for +details on the formulas used in conversion, see the @samp{xcolor} +documentation. + +By-name color specifications are single (case-dependent) words and are +compared with color names defined in @samp{dvipsnam.def} (from the +@samp{graphics} bundle), @samp{svgnam.def} and @samp{xcolor.sty} (from +the @samp{xcolor} bundle).

The +@samp{background} keyword must be followed by a color specification. +That color specification is used as a fill color for the background. The +last @samp{background} special on a page is the one that gets used, and +is used for the whole of the page image. (This is possible because the +prescan phase of dvipng notices all of the color specials so that the +appropriate information can be written out during the second phase.) + +The @samp{color} special itself has three forms. The first is just +@samp{color} followed by a color specification. In this case, the +current global color is set to that color; the color stack must be empty +when such a command is executed. + +The second form is @samp{color push} followed by a color specification. +This saves the current color on the color stack and sets the color to be +that given by the color specification. This is the most common way to +set a color. + +The final form of the @samp{color} special is just @samp{color pop}, +with no color specification; this says to pop the color last pushed on +the color stack from the color stack and set the current color to be +that color. + +dvipng correctly handles these color specials across pages, even when +the pages are rendered repeatedly or in reverse order. + +@node Diagnosing problems +@chapter Diagnosing problems + +@cindex problems +@cindex trouble +@cindex debugging + +You've gone through all the trouble of installing dvipng, carefully read +all the instructions in this manual, and still can't get something to +work.

To take advantage of this, you should have at least FreeType +2.1.9. + +FreeType 2 will enable direct support for PostScript and TrueType fonts, +so that dvipng will not need to generate bitmapped variants on disk of +the @TeX{} fonts since modern @TeX{} distributions include PostScript +versions of them. Then, you can render images at different (and unusual) +resolutions without cluttering the disk with lots of bitmapped fonts. + +Finally, it will enable subfont support in dvipng. That is, if you want +to render CJK-@LaTeX{} characters, you must have FreeType 2 installed. + +@item libpng and libz + +To be able to compress and write PNG files to disk, dvipng (or really +libgd) uses libpng which in turn uses libz.

This may be because @emph{only} +$SELFAUTOLOC, $SELFAUTODIR, and $SELFAUTOPARENT are used in the texmf +tree configuration file @samp{texmf.cnf}. If so, give the switch +@samp{--enable-selfauto-set} to @samp{./configure}. This will make +dvipng adjust these three internally so that kpathsea thinks that +dvipng @emph{is} installed in the texmf tree. + +@node Advice for non-privileged users +@section Installation for non-privileged users + +Often people without system administration privileges want to install +software for their private use. In that case you need to specify more +options to the @file{configure} script, usually this is done by using +the @samp{--prefix} option to the @file{configure} script, and let it +point to the personal home directory. In that way, resulting binaries +will be installed under the @file{bin} subdirectory of your home +directory, manual pages under @file{man} and so on.
