GENERAL PUBLIC LICENSE - Version 3, 29 June 2007 - - Copyright (C) 2007 Free Software Foundation, Inc. - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The GNU General Public License is a free, copyleft license for -software and other kinds of works. - - The licenses for most software and other practical works are designed -to take away your freedom to share and change the works. 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. - - - Copyright (C) - - 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 . - -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: - - Copyright (C) - 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 -. - - 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. If this is what you want to do, use the GNU Lesser General -Public License instead of this License.

It uses -those values to create a `Makefile' in each directory of the package. -It may also create one or more `.h' files containing system-dependent -definitions. Finally, it creates a shell script `config.status' that -you can run in the future to recreate the current configuration, and a -file `config.log' containing compiler output (useful mainly for -debugging `configure'). - - It can also use an optional file (typically called `config.cache' -and enabled with `--cache-file=config.cache' or simply `-C') that saves -the results of its tests to speed up reconfiguring. (Caching is -disabled by default to prevent problems with accidental use of stale -cache files.) - - If you need to do unusual things to compile the package, please try -to figure out how `configure' could check whether to do them, and mail -diffs or instructions to the address given in the `README' so they can -be considered for the next release. If you are using the cache, and at -some point `config.cache' contains results you don't want to keep, you -may remove or edit it. - - The file `configure.ac' (or `configure.in') is used to create -`configure' by a program called `autoconf'. You only need -`configure.ac' if you want to change it or regenerate `configure' using -a newer version of `autoconf'. - -The simplest way to compile this package is: - - 1. `cd' to the directory containing the package's source code and type - `./configure' to configure the package for your system. If you're - using `csh' on an old version of System V, you might need to type - `sh ./configure' instead to prevent `csh' from trying to execute - `configure' itself. - - Running `configure' takes awhile. While running, it prints some - messages telling which features it is checking for. - - 2. Type `make' to compile the package. - - 3. Optionally, type `make check' to run any self-tests that come with - the package. - - 4. Type `make install' to install the programs and any data files and - documentation. - - 5. You can remove the program binaries and object files from the - source code directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile the package for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the package's developers. If you use it, you may have to get - all sorts of other programs in order to regenerate files that came - with the distribution. - -Compilers and Options -===================== - - Some systems require unusual options for compilation or linking that -the `configure' script does not know about. Run `./configure --help' -for details on some of the pertinent environment variables. - - You can give `configure' initial values for configuration parameters -by setting variables in the command line or in the environment. Here -is an example: - - ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix - - *Note Defining Variables::, for more details. - -Compiling For Multiple Architectures -==================================== - - You can compile the package for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you must use a version of `make' that -supports the `VPATH' variable, such as GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. - - If you have to use a `make' that does not support the `VPATH' -variable, you have to compile the package for one architecture at a -time in the source code directory. After you have installed the -package for one architecture, use `make distclean' before reconfiguring -for another architecture. - -Installation Names -================== - - By default, `make install' will install the package's files in -`/usr/local/bin', `/usr/local/man', etc. You can specify an -installation prefix other than `/usr/local' by giving `configure' the -option `--prefix=PATH'. - - You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If you -give `configure' the option `--exec-prefix=PATH', the package will use -PATH as the prefix for installing programs and libraries. -Documentation and other data files will still use the regular prefix. - - In addition, if you use an unusual directory layout you can give -options like `--bindir=PATH' to specify different values for particular -kinds of files. Run `configure --help' for a list of the directories -you can set and what kinds of files go in them. - - If the package supports it, you can cause programs to be installed -with an extra prefix or suffix on their names by giving `configure' the -option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. - -Optional Features -================= - - Some packages pay attention to `--enable-FEATURE' options to -`configure', where FEATURE indicates an optional part of the package. -They may also pay attention to `--with-PACKAGE' options, where PACKAGE -is something like `gnu-as' or `x' (for the X Window System). The -`README' should mention any `--enable-' and `--with-' options that the -package recognizes. - - For packages that use the X Window System, `configure' can usually -find the X include and library files automatically, but if it doesn't, -you can use the `configure' options `--x-includes=DIR' and -`--x-libraries=DIR' to specify their locations. - -Specifying the System Type -========================== - - There may be some features `configure' cannot figure out -automatically, but needs to determine by the type of machine the package -will run on. Usually, assuming the package is built to be run on the -_same_ architectures, `configure' can figure that out, but if it prints -a message saying it cannot guess the machine type, give it the -`--build=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name which has the form: - - CPU-COMPANY-SYSTEM - -where SYSTEM can have one of these forms: - - OS KERNEL-OS - - See the file `config.sub' for the possible values of each field. If -`config.sub' isn't included in this package, then this package doesn't -need to know the machine type. - - If you are _building_ compiler tools for cross-compiling, you should -use the `--target=TYPE' option to select the type of system they will -produce code for. - - If you want to _use_ a cross compiler, that generates code for a -platform different from the build platform, you should specify the -"host" platform (i.e., that on which the generated programs will -eventually be run) with `--host=TYPE'. - -Sharing Defaults -================ - - If you want to set default values for `configure' scripts to share, -you can create a site shell script called `config.site' that gives -default values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: not all `configure' scripts look for a site script. - -Defining Variables -================== - - Variables not defined in a site shell script can be set in the -environment passed to `configure'. However, some packages may run -configure again during the build, and the customized values of these -variables may be lost. In order to avoid this problem, you should set -them in the `configure' command line, using `VAR=value'. For example: - - ./configure CC=/usr/local2/bin/gcc - -will cause the specified gcc to be used as the C compiler (unless it is -overridden in the site shell script). - -`configure' Invocation -====================== - - `configure' recognizes the following options to control how it -operates. - -`--help' -`-h' - Print a summary of the options to `configure', and exit. - -`--version' -`-V' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`--cache-file=FILE' - Enable the cache: use and save the results of the tests in FILE, - traditionally `config.cache'. FILE defaults to `/dev/null' to - disable caching. - -`--config-cache' -`-C' - Alias for `--cache-file=config.cache'. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. To - suppress all normal output, redirect it to `/dev/null' (any error - messages will still be shown). - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`configure' also accepts some other, not widely useful, options. Run -`configure --help' for more details. - diff --git a/Build/source/texk/dvisvgm/dvisvgm-1.0.3/LGPL-2.1.txt b/Build/source/texk/dvisvgm/dvisvgm-1.0.3/LGPL-2.1.txt deleted file mode 100644 index 602bfc94635..00000000000 --- a/Build/source/texk/dvisvgm/dvisvgm-1.0.3/LGPL-2.1.txt +++ /dev/null @@ -1,504 +0,0 @@ - GNU LESSER GENERAL PUBLIC LICENSE - Version 2.1, February 1999 - - Copyright (C) 1991, 1999 Free Software Foundation, Inc. - 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - -[This is the first released version of the Lesser GPL.

You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -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 this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights.

You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. 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 not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -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 -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the 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 -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "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 -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY 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 -LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of the -ordinary General Public License). - - To apply these terms, attach the following notices to the library. It is -safest to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This library 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 2.1 of the License, or (at your option) any later version. - - This library 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.

It converts - DVI files to the XML-based scalable vector graphics format SVG. - - -DEPENDENCIES - - dvisvgm relies on the following free libraries: - * FreeType 2 (http://www.freetype.org) - This library is used to extract glyph outlines - from PFB files. - - * Ghostscript (http://pages.cs.wisc.edu/~ghost) - The PostScript special handler requires the Ghostscript - library libgs.so (Linux) or gsdll32.dll (Windows) to be - installed. If the configure script finds the corresponing - Ghostscript development files on the system, it directly - links against libgs.so. Otherwise, the library is looked up - at runtime and PostScript support is enabled only if libgs.so - could be found. - Due to incompatible changes of the Ghostscript API, dvisvgm - requires Ghostscript 8.31 or later. - - * kpathsea - This library is part of the Web2C package and is - usually installed in conjunction with a TeX distribution. - kpathsea provides functions for searching files in the - large texmf tree. - - * potracelib (http://potrace.sourceforge.net) - Peter Selinger's bitmap tracing library is utilized to - vectorize Metafont's bitmap output. - potracelib is now part of the dvisvgm source tarball, so - you don't need to create the library seperately any longer. - - * zlib (http://www.zlib.org) - Compressed SVG files are produced by using functions - of this library and the Gzstream wrapper classes - (http://www.cs.unc.edu/Research/compgeom/gzstream) - which are licensed under LGPL version 2.1 (or optionally any - later version) and should be included with this package. - - If you want to build and run the testsuite located in the tests - subdirectory, you also need the googletest libraries - (http://code.google.com/p/googletest). - - -COMPILATION - - Quick installation info: - * type "./configure" - * type "make" - * type "make install" as root (or "sudo make install") - - For generic configuration instructions see the file INSTALL. - - The configure script should recognize all necessary parameters. - If a library is installed but not detected, specify its location - as commandline parameter of configure, e.g. - ./configure --with-freetype=/usr/local/freetype - (all available options can be displayed with ./configure --help) - - The tracer module calls Metafont in case of lacking TFM or PFB files - via a system call. Please ensure that Metafont is installed and - reachable through the search path. - - To build Windows binaries I recommend MinGW in conjunction - with MSYS (http://www.mingw.org). If executed within MSYS - the configure script assumes that you want to build dvisvgm - for MiKTeX. In this case the necessary import libraries for - the MiKTeX DLLs will be created and linked. If not already done, - add the MiKTeX bin directory to your search path, otherwise the - required DLLs won't be found while running dvisvgm. - - If you don't like compiling the sources yourself, you can - download precompiled executables for Windows and MiKTeX - from sourceforge.net instead (see below). - - -USAGE - Information about the command-line interface and the available options - can be found in the manual page. - - -ADDITIONAL INFORMATION - This packacke is available from CTAN (dviware/dvisvgm) and can - be downloaded from the project website at sourceforge.net as well: - - http://dvisvgm.sourceforge.net - - Here you can find the sources, precompiled binaries and further additional - information about the converter and related topics. - - If you've found a bug please let me know.

Since the current SVG standard 1\&.1 doesn\(cqt specify multi\-page graphics, \fBdvisvgm\fR creates separate SVG files for each DVI page\&. Because of compatibility reasons, only the first page is converted by default\&. In order to select a different page or arbitrary page sequences, use option \fB\-p\fR which is described below\&. -.sp -\fBdvisvgm\fR should properly convert all pages that are made up of fonts and rules only\&. However, the utility also supports a couple of DVI extensions defined in terms of \fIDVI specials\fR\&. For a more detailed overview, see section \fBsupport of specials\fR below\&. -.sp -As SVG is a vector based graphics format, \fBdvisvgm\fR tries to convert the glyph outlines of all used fonts into scalable path descriptions\&. The fastest way to do that is to extract the path information from PFB (PostScript Type 1) files\&. So, if \fBdvisvgm\fR is able to find a PFB file for a required font, it will read the necessary information from it\&. -.sp -TeX\(cqs main source for font descriptions is Metafont though, which produces bitmap output\&. That\(cqs why not all obtainable TeX fonts are available in PFB format\&. In these cases \fBdvisvgm\fR tries to vectorize Metafont\(cqs output (GF fonts) by tracing the glyph bitmaps\&. The results are not as perfect as most (manually optimized) PFB outlines but are nonetheless really nice in most cases\&. -.SH "OPTIONS" -.PP -\fB\-a, \-\-trace\-all\fR=[\fIretrace\fR] -.RS 4 -This option forces dvisvgm to trace not just the actually needed glyphs but all glyphs of all bitmap fonts used in the DVI file\&. Since the tracing results are stored in the font cache, all following DVI conversions (without option -\fB\-\-trace\-all\fR) where these fonts are involved will be much faster\&. By default, dvisvgm traces only the actually needed glyphs and adds them to the cache\&. The boolean option -\fIretrace\fR -determines how to handle glyphs that are already stored in the cache\&. By default, these glyphs are skipped\&. Setting argument -\fIretrace\fR -to -\fIyes\fR -or -\fItrue\fR -forces dvisvgm to trace the corresponding bitmaps again\&. -.if n \{\ -.sp -.\} -.RS 4 -.it 1 an-trap -.nr an-no-space-flag 1 -.nr an-break-flag 1 -.br -.ps +1 -\fBNote\fR -.ps -1 -.br -This option only takes affect if font caching is active\&.

The parameter -\fIfmt\fR -takes either one of the format specifiers listed below or a sequence of four comma\- or whitespace\-separated length values -\fIx1\fR, -\fIy1\fR, -\fIx2\fR -and -\fIy2\fR\&. The latter define two diagonal corners of the bounding box\&. Each length value consists of a floating point number and an optional length unit (pt, bp, cm, mm, in, or pc)\&. If the unit is omitted, TeX points (pt) are assumed\&. -.sp -It\(cqs also possible to give only one length value -\fIl\fR\&. In this case the minimal bounding box is computed and enlarged by adding (\-\fIl\fR,\-\fIl\fR) to the upper left and (\fIl\fR,\fIl\fR) to the lower right corner\&. -.sp -Alternatively, the following format specifiers are supported: -.PP -\fBInternational DIN/ISO paper sizes\fR -.RS 4 -A\fIn\fR, B\fIn\fR, C\fIn\fR, D\fIn\fR, where -\fIn\fR -is a non\-negative integer, e\&.g\&.

Furthermore, it is also possible to disable the font caching mechanism completely with option -\fB\-\-cache=none\fR\&.

By default, the values stored in the font\(cqs TFM file are used to determine a glyph\(cqs extent\&. As these values are intended to realize optimal character placements and are not designed to represent the exact dimensions, they don\(cqt necessarily correspond with the bounds of the visual glyphs\&. Thus, the width and/or height of some glyphs may be larger than the respective TFM values\&. As a result, this can lead to clipped characters at the bounds of the SVG graphic\&. With option -\fB\-\-exact\fR, dvisvgm analyzes the actual shape of each character and derives a usually tight bounding box\&. -.RE -.PP -\fB\-h, \-\-help\fR -.RS 4 -Prints a short summary of all available command\-line options\&. -.RE -.PP -\fB\-\-libgs=filename\fR -.RS 4 -This option is only available if the Ghostscript library is not directly linked to dvisvgm and PostScript support was not completely disabled\&.

The parameter -\fIpattern\fR -is a string that may contain the variables -\fB%f\fR -and -\fB%p\fR\&. -\fB%f\fR -stands for the base name of the DVI file, i\&.e\&. the DVI filename without suffix, and -\fB%p\fR -is the current page number\&. By default, the pattern is -\fB%f\-%p\&.svg\fR -if the DVI file consists of more than one page, and -\fB%f\&.svg\fR -otherwise\&. That means, a DVI file -\fIfoo\&.dvi\fR -is converted to -\fIfoo\&.svg\fR -if -\fIfoo\&.dvi\fR -is a single\-page document\&. Otherwise, multiple SVG files -\fIfoo\-01\&.svg\fR, -\fIfoo\-02\&.svg\fR, etc\&. are produced\&.

In order to stay compatible with previous versions, the default page sequence is 1\&. dvisvgm therefore converts only the first page and not the whole document in case option -\fB\-\-page\fR -is not given\&. Usually, page ranges consist of two numbers denoting the first and last page to be converted\&. If the conversion is to be started at page 1, or if it should continue up to the last DVI page, the first or second range number can be omitted, respectively\&. Example: -\fB\-\-page=\-10\fR -converts all pages up to page 10, -\fB\-\-page=10\-\fR -converts all pages starting with page 10\&.

Since the current SVG standard 1.1 doesn't -specify multi-page graphics, *dvisvgm* creates separate SVG files for each DVI page. -Because of compatibility reasons, only the first page is converted by default. In order -to select a different page or arbitrary page sequences, use option *-p* which is described below. - -*dvisvgm* should properly convert all pages that are made up of fonts and rules only. -However, the utility also supports a couple of DVI extensions defined in terms of 'DVI specials'. -For a more detailed overview, see section *support of specials* below. - -As SVG is a vector based graphics format, *dvisvgm* tries to convert the glyph -outlines of all used fonts into scalable path descriptions. The fastest way to do that -is to extract the path information from PFB (PostScript Type 1) files. So, if *dvisvgm* is able -to find a PFB file for a required font, it will read the necessary information from it. - -TeX's main source for font descriptions is Metafont though, which produces bitmap output. That's why -not all obtainable TeX fonts are available in PFB format. In these cases *dvisvgm* tries -to vectorize Metafont's output (GF fonts) by tracing the glyph bitmaps. The results are not -as perfect as most (manually optimized) PFB outlines but are nonetheless really nice in most cases. - - -OPTIONS -------- -*-a, --trace-all*=['retrace']:: -This option forces dvisvgm to trace not just the actually needed glyphs but all -glyphs of all bitmap fonts used in the DVI file. Since the tracing results are stored in -the font cache, all following DVI conversions (without option *--trace-all*) where these -fonts are involved will be much faster. By default, dvisvgm traces only the actually -needed glyphs and adds them to the cache. -The boolean option 'retrace' determines how to handle glyphs that are already stored in the cache. -By default, these glyphs are skipped. Setting argument 'retrace' to 'yes' or -'true' forces dvisvgm to trace the corresponding bitmaps again. -+ -[NOTE] -This option only takes affect if font caching is active. Thus, *--trace-all* cannot be -combined with option *--cache=none*. -+ - - -*-b, --bbox*='fmt':: -Sets the bounding box of the generated graphic to the specified format. The parameter 'fmt' -takes either one of the format specifiers listed below or a sequence of four comma- or -whitespace-separated length values 'x1', 'y1', 'x2' and 'y2'. The latter define two diagonal -corners of the bounding box. Each length value consists of a floating point number and an optional -length unit (pt, bp, cm, mm, in, or pc). If the unit is omitted, TeX points (pt) are assumed. -+ -It's also possible to give only one length value 'l'. In this case the minimal bounding box -is computed and enlarged by adding (-'l',-'l') to the upper left and ('l','l') to the lower -right corner. -+ -Alternatively, the following format specifiers are supported: - - *International DIN/ISO paper sizes*;; - A__n__, B__n__, C__n__, D__n__, where 'n' is a non-negative integer, e.g. A4 or a4 for DIN/ISO A4 - format (210mm × 297mm). - - *North American paper sizes*;; - invoice, executive, legal, letter, ledger - - *Special bounding box sizes*;; -[horizontal] - *dvi*::: the page size stored in the DVI file will be used - *min*::: the minimal bounding box will be computed and assigned - *none*::: no bounding box will be assigned - -// - *Page orientation*;; - The default page orientation for DIN/ISO and American paper sizes is 'portrait', - i.e. 'width' < 'height'. Appending *-landscape* or simply *-l* to the format - string switches to 'landscape' mode ('width' > 'height'). For symmetry reasons you can - also explicitly add *-portrait* or *-p* to indicate the default portrait format. - Note that these suffixes are part of the size string and not separate options. Thus - they must directly follow the above mentioned size specifiers without additional blanks. - Furthermore, the orientation suffixes can't be used with *dvi*, *min* and *none*. -+ -[NOTE] -Option *-b, --bbox* only affects the bounding box and does not transform the page content. Hence if -you choose a landscape format the page won't be rotated. -+ -// - -// -*-c, --scale*='sx'[,'sy']:: -Scales page content horizontally by 'sx' and vertically by 'sy'. This option is equivalent -to *-TS*'sx','sy'. - - -*-C, --cache*[='dir']:: -To speed up the conversion process of bitmap fonts, *dvisvgm* saves intermediate conversion -information in cache files. By default, these files are stored in $HOME/.dvisvgm. If you prefer -a different location use option *--cache* to overwrite the default. Furthermore, it is also possible -to disable the font caching mechanism completely with option *--cache=none*. If argument 'dir' is omitted, -dvisvgm prints the path of the default cache directory and some information about the stored fonts. - - -*--color*:: -Enables colorization of messages printed during the conversion process. - - -*-e, --exact*:: -If this option is given, dvisvgm computes the precise bounding box of each character. By default, -the values stored in the font's TFM file are used to determine a glyph's extent. As these values are -intended to realize optimal character placements and are not designed to represent the exact dimensions, -they don't necessarily correspond with the bounds of the visual glyphs. Thus, the width and/or height -of some glyphs may be larger than the respective TFM values. As a result, this can lead to clipped -characters at the bounds of the SVG graphic. With option *--exact*, dvisvgm analyzes the actual shape -of each character and derives a usually tight bounding box. - - -*-h, --help*:: -Prints a short summary of all available command-line options. - - -*--libgs=filename*:: -This option is only available if the Ghostscript library is not directly linked to dvisvgm and -PostScript support was not completely disabled. In this case, dvisvgm tries to load the shared -GS library dynamically during runtime. By default, it expects the library's name to be libgs.so -(on Unix-like systems) or gsdll32.dll (Windows). Option *--libgs* can be used to give a different -name. Alternatively, the GS library name can also be set by the environment variable *LIBGS*. -The latter has a less precedence than the command-line option. - - -*-l, --list-specials*:: -Prints a list of registered special handlers and exits. Each handler processes a set of special -statements belonging to the same category. The categories are identified by the -prefix of the special statements. It's usually a leading word -separated from the rest of the statement by a colon or a blank, e.g. 'color' or 'ps'. - - -*--keep*:: -Disables the removal of temporary files as created by Metafont (usually .gf, .tfm, and .log files). - - -*-m, --map-file*='file':: -Sets the map file that is used to look up font names and encodings. *dvisvgm* does not provide -its own map file but tries to use available ones coming with *dvips* or *dvipdfm*. If -option *-m* is not given *dvisvgm* looks for +ps2pk.map+, +dvipdfm.map+, and +psfonts.map+ (in this order). -Without further options, the file specified by option *-m* will be used instead of the -default maps. If you want *dvisgvm* to load the given file additionally to the default maps, add a -leading '+' to the file/path, e.g. `--map-file=+myfonts.map`. -For further information about the file format see the manuals of *dvips* and *dvipdfm*. - - -*-M, --mag*='factor':: -Sets the maginfication factor used for Metafont calls prior tracing the glyphs. -The larger this value the better the tracing results. Nevertheless -large magnification values can cause Metafont arithmetic errors due to number -overflows. So use this option with care. The default setting usually produces -nice results. - - -*-n, --no-fonts*:: -If this option is given, *dvisvgm* doesn't create font elements but uses paths instead. The -resulting SVG file is usually bigger but concurrently more compatible with most applications that -don't support SVG fonts yet. This option implies *--no-styles*. - - -*-S, --no-specials*[='names']:: -Disable processing of special commands that are embedded in the DVI file. If no further -parameter is given, all specials are ignored. To selectively disable sets of specials, -an optional comma-separated list of names can be appended to this option. A 'name' is a unique -identifier referencing a special handler. Option *--list-specials* lists all currently available -handlers and their names. -All unsupported special statements are silently ignored. - - -*--no-styles*:: -By default, *dvisvgm* uses CSS styles and class attributes to reference fonts because it's more -compact than repeatedly set the complete font information in each text element. However, if you -prefer direct font references, the default behavior can be disabled with option *--no-styles*. - - -*--no-mktexmf*:: -Suppresses the generation of missing font files. If *dvisvgm* can't find a font file -through the kpathsea lookup mechanism, it calls the external tools mktextfm or mktexmf by -default. This option disables these calls. - - -*-o, --output*='pattern':: -Sets the name pattern of the output file. The parameter 'pattern' is a string that may -contain the variables *%f* and *%p*. *%f* stands for the base name of the DVI file, i.e. -the DVI filename without suffix, and *%p* is the current page number. -By default, the pattern is *%f-%p.svg* if the DVI file consists of more than one page, and -*%f.svg* otherwise. That means, a DVI file 'foo.dvi' is converted to 'foo.svg' if 'foo.dvi' -is a single-page document. Otherwise, multiple SVG files 'foo-01.svg', 'foo-02.svg', etc. are -produced. In Windows environments, the percent sign is used to get the value of environment -variables, and must therefore be protected by a second percent sign, e.g. *--output=%%f-%%p*. - - -*-p, --page*='ranges':: -This option sets the pages to be processed. Parameter 'ranges' consists of a comma-separated list -of single page numbers and/or page ranges. A page range is a pair of numbers separated by a hyphen, -e.g. 5-12. Thus, a page sequence might look like this: 2-4,6,9-12,15. It doesn't matter if a page -is given more than once or if page ranges overlap. *dvisvgm* always extracts the page numbers in -ascending order and converts them only once. -In order to stay compatible with previous versions, the default page sequence is 1. dvisvgm -therefore converts only the first page and not the whole document in case option *--page* is not given. -Usually, page ranges consist of two numbers denoting the first and last page to be converted. -If the conversion is to be started at page 1, or if it should continue up to the last DVI page, the -first or second range number can be omitted, respectively. Example: *--page=-10* converts all -pages up to page 10, *--page=10-* converts all pages starting with page 10. -Please consider that the page values don't refer to the page numbers printed on the page. -Instead, the physical page count is expected, where the first page always gets number 1. - - -*-P, --progress*[='delay']:: -Enables a simple progress indicator shown when time-consuming operations like -PostScript specials are processed. The indicator doesn't appear before the given -delay (in seconds). The default delay value is 0.5 seconds. - - -*-r, --rotate*='angle':: -Rotates page content clockwise by 'angle' degrees around the page center. -This option is equivalent to *-TR*'angle'. - - -*-s, --stdout*:: -Don't write output to a file but redirect it to *stdout*. - - -*-t, --translate*='tx'[,'ty']:: -Translates (moves) page content in direction of vector ('tx','ty'). This option is -equivalent to *-TT*'tx','ty'. - - -*-T, --transform*='commands':: -Applies a sequence of transformations to the SVG content. Each transformation is described -by a 'command' that begins with a capital letter followed by a list of comma-separated -parameters. Following transformation commands are supported: - - *T* 'tx'[,'ty'];; - Translates (moves) page in direction of vector ('tx','ty'). If 'ty' is omitted, - 'ty'=0 is assumed. - The expected unit length of 'tx' and 'ty' are TeX points (1pt = 1/72.27in). However, there - are several constants defined to simplify the unit conversion (see below). - - *S* 'sx'[,'sy'];; - Scales page horizontally by 'sx' and vertically by 'sy'. If 'sy' is omitted - 'sy'='sx' is assumed. - - *R* 'angle'[,'x','y'];; - Rotates page clockwise by 'angle' degrees around point ('x','y'). If the optional - arguments 'x' and 'y' are omitted the page will be rotated around its center depending on - the chosen page format. When option *-bnone* is given, the rotation center is origin (0,0). - - *KX* 'angle';; - Skews page along the 'x'-axis by 'angle' degrees. Argument 'angle' can take any value - except 90+180__k__, where 'k' is an integer. - - *KY* 'angle';; - Skews page along the 'y'-axis by 'angle' degrees. Argument 'angle' can take any value - except 90+180__k__, where 'k' is an integer. - - *FH* ['y'];; - Mirrors (flips) page at the horizontal line through point (0,'y'). Omitting the optional argument - leads to 'y'='h'/2, where 'h' denotes the page height (see 'pre-defined constants' below). - - *FV* ['x'];; - Mirrors (flips) page at the vertical line through point ('x',0). Omitting the optional argument - leads to 'x'='w'/2, where 'w' denotes the page width (see 'pre-defined constants' below). - - *M* 'm1',...,'m6';; - Applies a transformation described by the 3×3 matrix - \(('m1','m2','m3'),('m4','m5','m6'),(0,0,1)), where the inner triples denote - the rows. - -+ -[NOTE] -================================================================================================= -All transformation commands of option *-T, --transform* are applied in the order of their appearance. Multiple commands can -optionally be separated by spaces. In this case the whole transformation string has to be enclosed in double -quotes. All parameters are expressions of floating point type. You can either give plain numbers -or arithmetic terms combined by the operators *+* (addition), *-* (substraction), -*** (multiplication), */* (division) or *%* (modulo) with common associativity and -precedence rules. Parentheses may be used as well. - -Additionally, some pre-defined constants are provided: - -[horizontal] -*ux*:: horizontal position of upper left page corner in TeX point units -*uy*:: vertical position of upper left page corner in TeX point units -*h*:: page height in TeX point units (0 in case of *-bnone*) -*w*:: page width in TeX point units (0 in case of *-bnone*) - -Furthermore, you can use the length constants *pt*, *mm*, *cm* and *in*, e.g. -+2cm+ or +1.6in+. Thus, option +-TT1in,0R45+ moves the page content 1 inch to the right and rotates it -by 45 degrees around the page center afterwards. - -For single transformations you can also use options *-c*, *-t* and *-r*. Note that -the order in which these options are given is not significant, i.e. you can't use them to describe -transformation sequences. They are simply independent shorthand options for common transformations. - -================================================================================================= -+ - -*-v, --verbosity*='level':: -Controls the type of messages printed during a *dvisvgm* run: -[horizontal] - *0*;; no message output - *1*;; error messages only - *2*;; warning messages only - *4*;; informational messages only - -+ -[NOTE] -By adding these values you can combine the categories. The default level is 7, i.e. all -messages are printed. -+ - - -*-V, --version*:: -Prints the version number and exits. - - -*-z, --zip*[='level']:: -Creates a compressed SVG file with suffix .svgz. The optional argument specifies the compression -level. Valid values are in the range of 1 to 9 (default is 9). Larger values cause better compression -results but take more computation time. -+ -CAUTION: This option cannot be combined with *-s, --stdout*. - - -SUPPORT OF SPECIALS -------------------- -*dvisvgm* supports several sets of special commands that can be used to enrich DVI files with additional -features, like color, graphics or hyperlinks. The evaluation of special commands is done by various handlers, -where each handler is responsible for all special statements of the same command set, i.e. commands beginning -with the same prefix. To get a list of actually provided special handlers, use option *--list-specials* (see above). - -*bgcolor*:: -Special statement for changing the background/page color. Since SVG 1.1 doesn't support background colors, -*dvisvgm* inserts a rectangle of the chosen color. In the current version, this rectangle always gets the size -of the minimal bounding box. This command is part of the color special set but is handled separately in order -to let the user turn it off. For an overview of the command syntax, see the documentation of *dvips*, for instance. - - -*color*:: -Statements of this command set provide instructions to change the text/paint color. For an overview of the -exact syntax, see the documentation of *dvips*, for instance. - -*dvisvgm*:: -*dvisvgm* offers its own small set of specials. The following list gives a brief overview. - *dvisvgm:raw* 'text';; - Adds an arbitrary sequence of characters to the SVG output. *dvisvgm* does not perform any validation here, - thus the user of this special has to ensure that the resulting SVG is still valid. The parameter 'text' may - contain the macros *{?x}*, *{?y}*, and *{?color}* which are expanded to the current 'x' or 'y' coordinate - and the current color, respectively. Also, the macro *{?nl}* expands to a newline character. - - *dvisvgm:img* 'width' 'height' 'file';; - Creates an image element at the current graphic position referencing the given file. JPEG, PNG, and SVG images - can be used here. However, *dvisvgm* does not check the file format or the file name suffix. The lengths 'width' - and 'height' must be given as plain floating point numbers in TeX point units (1in = 72.27pt). - - *dvisvgm:bbox* n[ew] 'name';; - Defines or resets a local bounding box called 'name'. The name may consist of letters and digits. - While processing a DVI page, dvisvgm continuously updates the (global) bounding box of the current page in order to - determine the minimal rectangle containing all visible page components (characters, images, drawing elements etc.). - Additionally to the global bounding box, the user can request an arbitrary number of named local bounding boxes. - Once defined, these boxes are updated together with the global bounding box starting with the first character that - follows the definition. Thus, the local boxes can be used to compute the extent of parts of the page. This is useful - for scenarios where the generated SVG file is post-processed. - In conjunction with special dvisvgm:raw, the macro *{?bbox 'name'}* expands to the four values 'x', 'y', 'w', and 'h' - (separated by spaces) specifying the coordinates of the upper left corner, width, and height of the local box 'name'. - If box 'name' wasn't previously defined, all four values equal zero. - - *dvisvgm:bbox* 'width' 'height' ['depth'];; - Updates the bounding box of the current page by embedding a virtual rectangle ('x', 'y', 'width', 'height') - where the lower left corner is located at the current DVI drawing position ('x','y'). If the optional parameter 'depth' - is specified, dvisvgm embeds a second rectangle ('x', 'y', 'width', -__depth__). The lengths 'width', 'height' and - 'depth' must be given as plain floating point numbers in TeX point units (1in = 72.27pt). Depending on size and position - of the virtual rectangle, this command either enlarges the overall bounding box or leaves it as is. It's not possible - to reduce its extent. This special should be used in conjunction with *dvisvgm:raw* in order to properly update the viewport - of the page. - - *dvisvgm:bbox* a[bs] 'x1' 'y1' 'x2' 'y2';; - This variant of the bbox special updates the bounding box by embedding a virtual rectangle ('x1','y1','x2','y2'). - The points ('x1','y1') and ('x2','y2') denote two diagonal corners of the rectangle given in TeX point units. - - *dvisvgm:bbox* f[ix] 'x1' 'y1' 'x2' 'y2';; - This variant of the bbox special assigns an absolute (final) bounding box to the resulting SVG. After executing - this command, dvisvgm doesn't further alter the bounding box coordinates, except this special is called again later. - The points ('x1','y1') and ('x2','y2') denote two diagonal corners of the rectangle given in TeX point units. -+ -The following TeX snippet adds two raw SVG elements to the output and updates the bounding box accordingly: -+ ------------------------------------------------------------------------------------- -\special{dvisvgm:raw } -\special{dvisvgm:bbox 20 10 10} - -\special{dvisvgm:raw } -\special{dvisvgm:bbox abs 10 200 100 250} ------------------------------------------------------------------------------------- -+ - -*em*:: -These specials were introduced with the emTeX distribution by Eberhard Mattes. They provide line drawing -statements, instructions for embedding MSP, PCX, and BMP image files, as well as two PCL commands. -*dvisvgm* supports only the line drawing statements, all other em specials are silently ignored. -A description of the command syntax can be found in the DVI driver documentation coming with emTeX (see CTAN). - -// *html*:: -// The hyperref package uses a set of HTML anchor tags to indicate hyperlinks in DVI files. -// *dvisvgm* converts them to corresponding SVG elements. - -*ps*:: -The famous DVI driver *dvips* introduced its own set of specials in order to embed PostScript code into DVI files, -which greatly improves the capabilities of DVI documents. One aim of *dvisvgm* is to completely evaluate the -PostScript code and to convert a large amount of it to SVG. -Since PostScript is a rather complex language, *dvisvgm* does not try to implement its own PostScript interpreter but uses -Ghostscript instead. If the Ghostscript library was not linked while building dvisvgm, it is looked up and dynamically loaded -during runtime. In this case, dvisvgm looks for libgs.so on Unix-like systems, and gsdll32.dll on Windows. You can override these -default file names with the environment variable LIBGS. -The library must be installed and reachable through the ld search path (\*nix) or the PATH environment variable (Windows). -If it cannot be found, the evaluation of PostScript specials is disabled. Use option *--list-specials* to check whether -PS support is available, i.e. the entry 'ps' is present. - -*tpic*:: -The TPIC special set defines instructions for drawing simple geometric objects. Some LaTeX packages, like -eepic and tplot, use these specials to describe graphics. - - -EXAMPLES --------- --------------- -dvisvgm file --------------- -Converts first page of 'file.dvi' to 'file.svg'. - ---------------- -dvisvgm -z file ---------------- -Converts first page of 'file.dvi' to 'file.svgz' with default compression level 9. - -------------------------------------- -dvisvgm -p5 -z3 -ba4-l -onewfile file -------------------------------------- -Converts fifth page of 'file.dvi' to 'newfile.svgz' with compression level 3. -The bounding box is set to DIN/ISO A4 in landscape format. - ------------------------------------------------------ -dvisvgm --transform="R20,w/3,2h/5 T1cm,1cm S2,3" file ------------------------------------------------------ -Converts first page of 'file.dvi' to 'file.svg' where three transformations are applied. - - -ENVIRONMENT ------------ -*dvisvgm* uses the *kpathsea* library for locating the -files that it opens. Hence, the environment variables described in -the library's documentation influence the converter. - -If dvisvgm was linked without the Ghostscript library and PostScript support has not been disabled, -the shared Ghostscript library is looked up during runtime. The environment variable LIBGS can be -used to specify the file name of library. - -The pre-compiled Windows version of *dvisvgm* requires a working installation of MiKTeX 2.7 or above. -To enable evaluation of PostScript specials, the original Ghostscript DLL must be present. - -FILES ------ -The location of the following files is determined by the kpathsea library. -To check the actual kpathsea configuration you can use the *kpsewhich* utility. - -[horizontal] -**.enc*:: Font encoding files -**.fgd*:: Font glyph data files (cache files created by dvisvgm) -**.map*:: Font map files -**.mf*:: Metafont input files -**.pfb*:: PostScript Type 1 font files -**.pro*:: PostScript header/prologue files -**.tfm*:: TeX font metric files -**.ttf*:: TrueType font files -**.vf*:: Virtual font files - -SEE ALSO --------- -*tex(1), mf(1), mktexmf(1), grodvi(1), potrace(1)*, and the *kpathsea library* info documentation. - - -RESOURCES ---------- -Project home page::: http://dvisvgm.sourceforge.net -SourceForge project site::: http://sourceforge.net/projects/dvisvgm - - -AUTHOR ------- -Written by {author} <{email}> - - -COPYING -------- -Copyright (C) 2005-2010 by Martin Gieseking.
