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.

(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-1.8.1/LGPL-2.1.txt b/Build/source/texk/dvisvgm/dvisvgm-1.8.1/LGPL-2.1.txt deleted file mode 100644 index 602bfc94635..00000000000 --- a/Build/source/texk/dvisvgm/dvisvgm-1.8.1/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. It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. 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. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. 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.

If the configure script finds the corresponding - 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. - - * 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.

It supports the classic DVI format 2 as well as format 3 (created by pTeX in vertical mode), and format 5 which is also known as XDV (created by XeTeX)\&. Besides the basic DVI commands, dvisvgm also evaluates many so\-called \fIspecials\fR which heavily extend the capabilities of the DVI format\&. For a more detailed overview, see section \fBsupport of specials\fR below\&. -.sp -Since the current SVG standard 1\&.1 doesn\(cqt 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 \fB\-p\fR which is described below\&. -.sp -SVG is a vector\-based graphics format and therefore dvisvgm tries to convert the glyph outlines of all used fonts to scalable path descriptions\&. The fastest way to do that is to extract the path information from font files in PFB, TTF, or OTF format\&. If dvisvgm is able to find such a file, it extracts all necessary outline information about the glyphs from it\&. -.sp -However, TeX\(cqs main source for font descriptions is Metafont, which produces bitmap output (GF files)\&. That\(cqs why not all obtainable TeX fonts are available in a scalable format\&. In these cases, dvisvgm tries to vectorize Metafont\(cqs output by tracing the glyph bitmaps\&. The results are not as perfect as most (manually optimized) PFB or OTF counterparts, but are nonetheless really nice in most cases\&. -.sp -When running dvisvgm without option \fB\-\-no\-fonts\fR, \fIfont\fR elements (\&...) are used to embed the font data into the SVG files\&. Unfortunately, only few SVG renderes support these elements yet\&. Most web browsers and vector graphics applications don\(cqt evaluate them properly so that the text components of the resulting graphics might look strange\&. In order to create more compatible SVG files, command\-line option \fB\-\-no\-fonts\fR can be given to replace the font elements by plain graphics paths\&. -.SH "OPTIONS" -.PP -\fB\-a, \-\-trace\-all\fR=[\fIretrace\fR] -.RS 4 -This option forces dvisvgm to trace not only 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 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\&.

For symmetry reasons you can also explicitly add -\fB\-portrait\fR -or -\fB\-p\fR -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 size specifier without additional blanks\&.

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

In order to do so, a single -\fIpsfile\fR -special command is created and forwarded to the PostScript special handler\&. This option is only available if dvisvgm was built with PostScript support enabled, and requires Ghostscript to be available\&. See option -\fB\-\-libgs\fR -for further information\&. -.RE -.PP -\fB\-e, \-\-exact\fR -.RS 4 -If this option is given, dvisvgm computes the precise bounding box of each character\&. By default, the values stored in a font\(cqs TFM file are used to determine a glyph\(cqs extent\&. As these values are intended to implement 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, width and/or height of some glyphs may be larger (or smaller) than the respective TFM values\&. As a result, this can lead to clipped characters at the bounds of the SVG graphics\&. With option -\fB\-\-exact\fR -given, dvisvgm analyzes the actual shape of each character and derives a usually tight bounding box\&. -.RE -.PP -\fB\-m, \-\-fontmap\fR=\fIfilenames\fR -.RS 4 -Loads and evaluates a single or multiple font map files\&.

Multiple filenames must be separated by commas without leading and/or trailing whitespace\&. The map files are evaluated in the given order\&. By default, redefined mappings do not replace previous ones\&. However, each filename can be preceded by an optional mode specifier (\fB+\fR, -\fB\-\fR, or -\fB=\fR) to change this behavior: -.PP -+mapfile -.RS 4 -Only those entries in the given map file that don\(cqt redefine a font mapping are applied\&.

It supports the classic DVI format 2 as -well as format 3 (created by pTeX in vertical mode), and format 5 which is also known as -XDV (created by XeTeX). Besides the basic DVI commands, dvisvgm also evaluates many so-called -'specials' which heavily extend the capabilities of the DVI format. For a more detailed -overview, see section *support of specials* below. - -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. - -SVG is a vector-based graphics format and therefore dvisvgm tries to convert the glyph outlines -of all used fonts to scalable path descriptions. The fastest way to do that is to extract the -path information from font files in PFB, TTF, or OTF format. If dvisvgm is able to find such -a file, it extracts all necessary outline information about the glyphs from it. - -However, TeX's main source for font descriptions is Metafont, which produces bitmap output -(GF files). That's why not all obtainable TeX fonts are available in a scalable format. -In these cases, dvisvgm tries to vectorize Metafont's output by tracing the glyph bitmaps. -The results are not as perfect as most (manually optimized) PFB or OTF counterparts, but are -nonetheless really nice in most cases. - -When running dvisvgm without option *--no-fonts*, 'font' elements (...) are used to -embed the font data into the SVG files. Unfortunately, only few SVG renderes support these -elements yet. Most web browsers and vector graphics applications don't evaluate them properly -so that the text components of the resulting graphics might look strange. In order to create -more compatible SVG files, command-line option *--no-fonts* can be given to replace the font -elements by plain graphics paths. - - -OPTIONS -------- -*-a, --trace-all*=['retrace']:: -This option forces dvisvgm to trace not only 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 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*::: page size stored in the DVI file - *min*::: computes the minimal/tightest bounding box - *none*::: no bounding box is 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 size specifier 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, --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/cache. 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 together with further information about the stored fonts. -Additionally, outdated and corrupted cache files are removed. - - -*-j, --clipjoin*:: -This option tells dvisvgm to compute the intersection of clipping paths itself if necessary, -and not to delegate this task to the SVG renderer. The resulting SVG files are more portable -because some SVG renderers don't support intersections of clipping paths which are defined by -'clipPath' elements that contain a 'clip-path' attribute. - - -*--color*:: -Enables colorization of messages printed during the conversion process. The colors can be customized -via the environment variable +DVISVGM_COLORS+. See the ENVIRONMENT section below for further information. - - -*-E, --eps*:: -If this option is given, dvisvgm does not expect a DVI but an EPS input file, and tries to convert -it to SVG. In order to do so, a single 'psfile' special command is created and forwarded to the -PostScript special handler. -This option is only available if dvisvgm was built with PostScript support enabled, and requires -Ghostscript to be available. See option *--libgs* for further information. - - -*-e, --exact*:: -If this option is given, dvisvgm computes the precise bounding box of each character. By default, -the values stored in a font's TFM file are used to determine a glyph's extent. As these values are -intended to implement 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, width -and/or height of some glyphs may be larger (or smaller) than the respective TFM values. As a result, -this can lead to clipped characters at the bounds of the SVG graphics. With option *--exact* given, -dvisvgm analyzes the actual shape of each character and derives a usually tight bounding box. - - -*-m, --fontmap*='filenames':: -Loads and evaluates a single or multiple font map files. These files are required to resolve -font file names and encodings. dvisvgm does not provide its own map files but tries to read -available ones coming with dvips or dvipdfm. If option *--fontmap* is omitted, dvisvgm looks for the -default map files +ps2pk.map+, +dvipdfm.map+, and +psfonts.map+ (in this order). Otherwise, the -listed files are used. Multiple filenames must be separated by commas without leading and/or trailing -whitespace. -The map files are evaluated in the given order. By default, redefined mappings do not replace previous ones. -However, each filename can be preceded by an optional mode specifier (*+*, *-*, or *=*) to change this behavior: - - +mapfile;; - Only those entries in the given map file that don't redefine a font mapping are applied. - That's also the default mode if no mode specifier is given. - - -mapfile;; - Ensures that none of the font mappings defined in the given map file are used, i.e. previously - defined mappings for the specified fonts are removed. - - =mapfile;; - All mappings defined in the map file are applied. Previously defined settings for the same font - are replaced. -+ -If the first filename in the filename sequence is preceded by a mode specifier, dvisvgm loads the -default font map (see above) and applies the other map files afterwards. Otherwise, none of default -map files will be loaded automatically. -+ -Examples: *--fontmap=myfile1.map,+myfile2.map* loads `myfile1.map` followed by `myfile2.map` where all -redefinitions of `myfile2.map` are ignored. -*--fontmap==myfile1.map,-myfile2.map* loads the default map file followed by `myfile1.map` and `myfile2.map` -where all redefinitions of `myfile1.map` replace previous entries. Afterwards, all definitions for the fonts -given in `myfile2.map` are removed from the font map tree. -+ -For further information about the map file formats and the mode specifiers, see the manuals of dvips and dvipdfm. - - -*-h, --help*[='mode']:: -Prints a short summary of all available command-line options. The optional 'mode' parameter is -an integer value between 0 and 2. It selects the display variant of the help text. Mode 0 -lists all options divided into categories with section headers. This is also the default if -dvisvgm is called without parameters. Mode 1 lists all options ordered by the short option names, -while mode 2 sorts the lines by the long option names. - - -*--keep*:: -Disables the removal of temporary files as created by Metafont (usually .gf, .tfm, and .log files). - - -*--libgs*='filename':: -This option is only available if the Ghostscript library is not directly linked to dvisvgm and if -PostScript support was not completely disabled during compilation. 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.X (on Unix-like systems, where X is the ABI version of the library) or -gsdll32.dll/gsdll64.dll (Windows). Option *--libgs* can be used to give a different name. -Alternatively, it's also possible to set the GS library name by the environment variable +LIBGS+. -The latter has less precedence than the command-line option. - - -*-L, --linkmark*='style':: -Selects the method how to mark hyperlinked areas. The 'style' argument can take one of the values -'none', 'box', and 'line', where 'box' is the default, i.e. a rectangle is drawn around -the linked region if option *--linkmark* is omitted. Style argument 'line' just draws the lower edge of -the bounding rectangle, and 'none' tells dvisvgm not to add any visible objects to hyperlinks. -The lines and boxes get the current text color selected. In order to apply a different, constant color, -a colon followed by a color specifier can be appended to the style string. A 'color specifier' is either -a hexadecimal RGB value of the form '#RRGGBB', or a dvips color name as listed here: -http://en.wikibooks.org/wiki/LaTeX/Colors#The_68_standard_colors_known_to_dvips -+ -Moreover, argument 'style' can take a single color specifier to highlight the linked region by -a frameless box filled with that color. An optional second color specifier separated by colon -selects the frame color. -+ -Examples: *box:red* or *box:#ff0000* draws red boxes around the linked areas. *yellow:blue* creates -yellow filled rectangles with blue frames. - - -*-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. In most cases, 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'. - - -*-M, --mag*='factor':: -Sets the magnification factor applied in conjunction with 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. - - -*--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. -This option disables these calls. - - -*-n, --no-fonts*[='variant']:: -If this option is given, dvisvgm doesn't create SVG 'font' elements but uses 'paths' instead. The -resulting SVG files tend to be larger but they are concurrently more compatible with most applications that -don't support SVG fonts yet. The optional argument 'variant' selects the method how to substitute fonts -by paths. Variant 0 creates 'path' and 'use' elements. Variant 1 creates 'path' elements only. -Option *--no-fonts* implies *--no-styles*. - - -*-c, --scale*='sx'[,'sy']:: -Scales the page content horizontally by 'sx' and vertically by 'sy'. This option is equivalent -to *-TS*'sx','sy'. - - -*-S, --no-specials*[='names']:: -Disable processing of special commands 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 the unique -identifier referencing the intended 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 creates 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*. - - -*-o, --output*='pattern':: -Sets the name pattern of the output file. 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. -The default 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 indicates dereferenced 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 omitted. -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. - - -*-d, --precision*='digits':: -Specifies the maximal number of decimal places applied to floating-point attribute values. -All attribute values written to the generated SVG file(s) are rounded accordingly. The -parameter 'digits' allows integer values from 0 to 6, where 0 enables the automatic selection -of significant decimal places. This is also the default value if dvisvgm is called without -option *--precision*. - - -*-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) has elapsed. The default delay value is 0.5 seconds. - - -*-r, --rotate*='angle':: -Rotates the page content clockwise by 'angle' degrees around the page center. -This option is equivalent to *-TR*'angle'. - - -*-R, --relative*:: -SVG allows to define graphics paths by a sequence of absolute and/or relative commands, -i.e. each command expects either absolute coordinates or coordinates relative to the -current drawing position. By default, dvisvgm creates paths made up of absolute commands. -If option *--relative* is given, relative commands are created instead which slightly reduces -the size of the SVG files in most cases. - - -*-s, --stdout*:: -Don't write the SVG output to a file but redirect it to *stdout*. - - -*-T, --transform*='commands':: -Applies a sequence of transformations to the SVG content. Each transformation is described -by a 'command' beginning with a capital letter followed by a list of comma-separated -parameters. Following transformation commands are supported: - - *T* 'tx'[,'ty'];; - Translates (moves) the 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 the page horizontally by 'sx' and vertically by 'sy'. If 'sy' is omitted, - 'sy'='sx' is assumed. - - *R* 'angle'[,'x','y'];; - Rotates the 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 the 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 the 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) the 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) the 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), *-* (subtraction), -*** (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. - -================================================================================================= -+ -// - -// -*-t, --translate*='tx'[,'ty']:: -Translates (moves) the page content in direction of vector ('tx','ty'). This option is -equivalent to *-TT*'tx','ty'. - - -*-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*[='extended']:: -Prints the version of dvisvgm and exits. If the optional argument is set to 'yes', the -version numbers of the linked libraries are printed as well. - - -*-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 value is 9). Larger values cause better -compression results but take more computation time. -+ -CAUTION: This option cannot be combined with *-s, --stdout*. - - -*-Z, --zoom*[='factor']:: -Multiplies the 'width' and 'height' attributes of the SVG root element by argument 'factor' while -the coordinate system of the graphic is retained. As a result, most SVG viewers zoom the graphics -accordingly. If a negative zoom factor is given, the 'width' and 'height' attributes are omitted. - - -SUPPORT OF SPECIALS -------------------- -dvisvgm supports several sets of 'special commands' that can be used to enrich DVI files with additional -features, like color, graphics, and hyperlinks. The evaluation of special commands is delegated to dedicated -handlers. 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). This section gives an overview of the special commands currently supported. - -*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 into the generated SVG document. This rectangle always gets -the same size as the selected or computed bounding box. This background color 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 page section of the SVG document. dvisvgm does not perform - any validation here, thus the user has to ensure that the resulting SVG is still valid. Parameter 'text' - may contain the expressions *{?x}*, *{?y}*, and *{?color}* that expand to the current 'x' or 'y' coordinate - and the current color, respectively. Furthermore, *{?nl}* expands to a newline character. - - *dvisvgm:rawdef* 'text';; - This command is similar to *dvisvgm:raw*, but puts the raw text into the section of the SVG document - currently being generated. - - *dvisvgm:rawset* 'name' ... *dvisvgm:endrawset*;; - This pair of specials marks the begin and end of a definition of a named raw SVG fragment. All *dvisvgm:raw* - and *dvisvgm:rawdef* specials enclosed by *dvisvgm:rawset* and *dvisvgm:endrawset* are not evaluated - immediately but jointly stored under the given 'name' for later use. Once defined, the named fragment can be - referenced throughout the DVI file by *dvisvgm:rawput* (see below). - *dvisvgm:rawset* and *dvisvgm:endrawset* must not be nested, i.e. each call of *dvisvgm:rawset* has to be - followed by a corresponding call of *dvisvgm:endrawset* before another *dvisvgm:rawset* may occur. - Also, the identifier 'name' must be unique throughout the DVI file. Using *dvisvgm:rawset* multiple times - together with the same 'name' leads to a warning message. - - *dvisvgm:rawput* 'name';; - Inserts raw SVG fragments previously stored under the given 'name'. dvisvgm distinguishes between fragments - that were specified with *dvisvgm:raw* or *dvisvgm:rawdef*, and handles them differently: It inserts all - *dvisvgm:raw* parts every time *dvisvgm:rawput* is called, whereas the *dvisvgm:rawdef* portions go to the - section of the current SVG document only once. - - *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 update the viewport - of the page properly. - - *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 and ignores all other em specials silently. -A description of the command syntax can be found in the DVI driver documentation coming with emTeX (see CTAN). - -*html*:: -The hyperref specification defines several variants on how to mark hyperlinked areas in a DVI file. dvisvgm -supports the plain HyperTeX special constructs as created with hyperref package option 'hypertex'. -By default, all linked areas of the document are marked by a rectangle. Option *--linkmark* allows to change -this behavior. See above for further details. Information on syntax and semantics of the HyperTeX specials can be -found in the hyperref manual. - -*pdf*:: -pdfTeX and dvipdfmx introduced several special commands related to the generation of PDF files. Currently, only -two of them, 'pdf:mapfile' and 'pdf:mapline' are supported by dvisvgm. These specials allow modifying the font map -tree during the processing of DVI files. They are used by CTeX, for example. dvisvgm supports both, the dvips and -dvipdfm font map format. For further information on the command syntax and semantics, see the documentation of -\pdfmapfile in the pdfTeX user manual. - -*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 all -PostScript snippets and to convert a large amount of it to SVG. However, in contrast to dvips, dvisvgm uses floating point -arithmetics to compute the precise position of each graphic element, i.e. it doesn't round the coordinates. Therefore, -the relative locations of the graphic elements may slightly differ from those computed by dvips. -+ -Since PostScript is a rather complex language, dvisvgm does not try to implement its own PostScript interpreter but relies on -Ghostscript instead. If the Ghostscript library was not linked to the dvisvgm binary, it is looked up and loaded dynamically -during runtime. In this case, dvisvgm looks for 'libgs.so.X' on Unix-like systems (supported ABI versions: 7,8,9), -and for 'gsdll32.dll' or 'gsdll64.dll' on Windows. -You can override the default file names with environment variable +LIBGS+ or the command-line option *--libgs*. -The library must be reachable through the ld search path (\*nix) or the PATH environment variable (Windows). Alternatively, -the absolute file path can be specified. If the library cannot be found, dvisvgm disables the processing of PostScript specials. -Use option *--list-specials* to check whether PS support is available, i.e. entry 'ps' is present. -+ -The PostScript handler also recognizes and evaluates bounding box data generated by the 'preview' package with -option 'tightpage'. If the data is present in a DVI file, dvisvgm adapts the bounding box of the generated SVG file -accordingly, and prints a message showing the width, height, and depth of the box in TeX point units. Especially, -the depth value can be used to vertically align the SVG graphics with the baseline of surrounding text in HTML or XSL-FO -documents, for example. - -*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 the first page of 'file.dvi' to 'file.svg'. - ---------------- -dvisvgm -z file ---------------- -Converts the first page of 'file.dvi' to 'file.svgz' with default compression level 9. - -------------------------------------- -dvisvgm -p5 -z3 -ba4-l -onewfile file -------------------------------------- -Converts the 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 the 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 if PostScript support has not been disabled, -the shared Ghostscript library is looked up during runtime via dlopen(). The environment variable +LIBGS+ -can be used to specify path and file name of the library. - -The pre-compiled Windows versions of dvisvgm require a working installation of MiKTeX 2.9 or above. -dvisvgm does not work together with the portable edition of MiKTeX because it relies on MiKTeX's COM -interface only accessible in a local installation. -To enable the evaluation of PostScript specials, the original Ghostscript DLL 'gsdll32.dll' must be present -and reachable through the search path. 64-bit Windows builds require the 64-bit Ghostscript DLL 'gsdll64.dll'. -Both DLLs come with the corresponding Ghostscript installers available from www.ghostscript.com. - -The environment variable +DVISVGM_COLORS+ specifies the colors used to highlight various parts of dvisvgm's -message output. It is only evaluated if option *--color* is given. The value of +DVISVGM_COLORS+ is a list of -colon-separated entries of the form 'gg'='BF', where 'gg' denotes one of the color group indicators listed -below, and 'BF' are two hexadecimal digits specifying the background (first digit) and foreground/text color -(second digit). The color values are defined as follows: 0=black, 1=red, 2=green, 3=yellow, 4=blue, -5=magenta, 6=cyan, 7=gray, 8=bright red, 9=bright green, A=bright yellow, B=bright blue, C=bright magenta, -D=bright cyan, E=bright gray, F=white. Depending on the terminal, the colors may differ. Rather than changing -both the text and background color, it's also possible to change only one of them: An asterisk (*) in -place of a hexadecimal digit indicates the default text or background color of the terminal. - -All malformed entries in the list are silently ignored. - -[horizontal] -*er*:: error messages -*wn*:: warning messages -*pn*:: messages about page numbers -*ps*:: page size messages -*fw*:: information about the files written -*sm*:: state messages -*tr*:: messages of the glyph tracer -*pi*:: progress indicator - -*Example:* +er=01:pi=\*5+ sets the colors of error messages (+er+) to red (+1+) on black (+0+), and those -of progress indicators (+pi+) to cyan (+5+) on default background (+*+). - -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 - - -BUGS ----- -Please report bugs using the bug tracker at Launchpad (see https://launchpad.net/dvisvgm). - - -AUTHOR ------- -Written by {author} <{email}> - - -COPYING -------- -Copyright (C) 2005-2014 Martin Gieseking.

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. But first, please read +. diff --git a/Build/source/texk/dvisvgm/dvisvgm-1.9/ChangeLog b/Build/source/texk/dvisvgm/dvisvgm-1.9/ChangeLog new file mode 100644 index 00000000000..a3dde4b9f2c ---

1995, 1996, 1999, 2000, 2001, 2002 Free Software +Foundation, Inc. + + This file is free documentation; the Free Software Foundation gives +unlimited permission to copy, distribute and modify it. + +Basic Installation +================== + + These are generic installation instructions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. 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.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. 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. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. 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: + * Clipper (http://www.angusj.com/delphi/clipper.php) + To compute the insersections of two curved paths, dvisvgm + flattens the paths to polygons, intersects them using Clipper, + and reconstructs the curves afterwards. + + * FreeType 2 (http://www.freetype.org) + This library is used to extract the glyph outlines + from vector fonts (PFB, OTF, TTF). + + * Ghostscript (http://pages.cs.wisc.edu/~ghost) + The PostScript special handler requires the Ghostscript + library libgs.so (Linux) or gsdll32.dll/gsdll64.dll (Windows) + to be installed. If the configure script finds the corresponding + 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. + + * 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. + + If you don't like compiling the sources yourself, you can + download pre-compiled 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 package 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, pre-compiled binaries and further additional + information about the converter and related topics. + + If you've found a bug, please let me know.

\fIfile\fR [\&.dvi] +.sp +\fBdvisvgm\fR \-E [ \fIoptions\fR ] \fIfile\fR [\&.eps] +.SH "DESCRIPTION" +.sp +The command\-line utility \fBdvisvgm\fR converts DVI files, as generated by TeX/LaTeX, to the XML\-based scalable vector graphics format SVG\&. It supports the classic DVI format 2 as well as format 3 (created by pTeX in vertical mode), and format 5 which is also known as XDV (created by XeTeX)\&. Besides the basic DVI commands, dvisvgm also evaluates many so\-called \fIspecials\fR which heavily extend the capabilities of the DVI format\&. For a more detailed overview, see section \fBsupport of specials\fR below\&. +.sp +Since the current SVG standard 1\&.1 doesn\(cqt 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 \fB\-p\fR which is described below\&. +.sp +SVG is a vector\-based graphics format and therefore dvisvgm tries to convert the glyph outlines of all used fonts to scalable path descriptions\&. The fastest way to do that is to extract the path information from font files in PFB, TTF, or OTF format\&. If dvisvgm is able to find such a file, it extracts all necessary outline information about the glyphs from it\&. +.sp +However, TeX\(cqs main source for font descriptions is Metafont, which produces bitmap output (GF files)\&. That\(cqs why not all obtainable TeX fonts are available in a scalable format\&. In these cases, dvisvgm tries to vectorize Metafont\(cqs output by tracing the glyph bitmaps\&. The results are not as perfect as most (manually optimized) PFB or OTF counterparts, but are nonetheless really nice in most cases\&. +.sp +When running dvisvgm without option \fB\-\-no\-fonts\fR, \fIfont\fR elements (\&...) are used to embed the font data into the SVG files\&. Unfortunately, only few SVG renderes support these elements yet\&. Most web browsers and vector graphics applications don\(cqt evaluate them properly so that the text components of the resulting graphics might look strange\&. In order to create more compatible SVG files, command\-line option \fB\-\-no\-fonts\fR can be given to replace the font elements by plain graphics paths\&. +.SH "OPTIONS" +.PP +\fB\-a, \-\-trace\-all\fR=[\fIretrace\fR] +.RS 4 +This option forces dvisvgm to trace not only 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 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\&. Thus, +\fB\-\-trace\-all\fR +cannot be combined with option +\fB\-\-cache=none\fR\&. +.sp .5v +.RE +.RE +.PP +\fB\-b, \-\-bbox\fR=\fIfmt\fR +.RS 4 +Sets the bounding box of the generated graphic to the specified format\&. 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\&. A4 or a4 for DIN/ISO A4 format (210mm \(mu 297mm)\&. +.RE +.PP +\fBNorth American paper sizes\fR +.RS 4 +invoice, executive, legal, letter, ledger +.RE +.PP +\fBSpecial bounding box sizes\fR +.RS 4 +.TS +tab(:); +lt lt +lt lt +lt lt. +T{ +\fBdvi\fR +T}:T{ +page size stored in the DVI file +T} +T{ +\fBmin\fR +T}:T{ +computes the minimal/tightest bounding box +T} +T{ +\fBnone\fR +T}:T{ +no bounding box is assigned +T} +.TE +.sp 1 +.RE +.PP +\fBPage orientation\fR +.RS 4 +The default page orientation for DIN/ISO and American paper sizes is +\fIportrait\fR, i\&.e\&. +\fIwidth\fR +< +\fIheight\fR\&. Appending +\fB\-landscape\fR +or simply +\fB\-l\fR +to the format string switches to +\fIlandscape\fR +mode (\fIwidth\fR +> +\fIheight\fR)\&. For symmetry reasons you can also explicitly add +\fB\-portrait\fR +or +\fB\-p\fR +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 size specifier without additional blanks\&. Furthermore, the orientation suffixes can\(cqt be used with +\fBdvi\fR, +\fBmin\fR, and +\fBnone\fR\&. +.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 +Option +\fB\-b, \-\-bbox\fR +only affects the bounding box and does not transform the page content\&. Hence, if you choose a landscape format, the page won\(cqt be rotated\&. +.sp .5v +.RE +.RE +.RE +.PP +\fB\-C, \-\-cache\fR[=\fIdir\fR] +.RS 4 +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/cache\&. If you prefer a different location, use option +\fB\-\-cache\fR +to overwrite the default\&. Furthermore, it is also possible to disable the font caching mechanism completely with option +\fB\-\-cache=none\fR\&. If argument +\fIdir\fR +is omitted, dvisvgm prints the path of the default cache directory together with further information about the stored fonts\&. Additionally, outdated and corrupted cache files are removed\&. +.RE +.PP +\fB\-j, \-\-clipjoin\fR +.RS 4 +This option tells dvisvgm to compute the intersection of clipping paths itself if necessary, and not to delegate this task to the SVG renderer\&. The resulting SVG files are more portable because some SVG renderers don\(cqt support intersections of clipping paths which are defined by +\fIclipPath\fR +elements that contain a +\fIclip\-path\fR +attribute\&. +.RE +.PP +\fB\-\-color\fR +.RS 4 +Enables colorization of messages printed during the conversion process\&. The colors can be customized via the environment variable +DVISVGM_COLORS\&. See the ENVIRONMENT section below for further information\&. +.RE +.PP +\fB\-E, \-\-eps\fR +.RS 4 +If this option is given, dvisvgm does not expect a DVI but an EPS input file, and tries to convert it to SVG\&. In order to do so, a single +\fIpsfile\fR +special command is created and forwarded to the PostScript special handler\&. This option is only available if dvisvgm was built with PostScript support enabled, and requires Ghostscript to be available\&. See option +\fB\-\-libgs\fR +for further information\&. +.RE +.PP +\fB\-e, \-\-exact\fR +.RS 4 +If this option is given, dvisvgm computes the precise bounding box of each character\&. By default, the values stored in a font\(cqs TFM file are used to determine a glyph\(cqs extent\&. As these values are intended to implement 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, width and/or height of some glyphs may be larger (or smaller) than the respective TFM values\&. As a result, this can lead to clipped characters at the bounds of the SVG graphics\&. With option +\fB\-\-exact\fR +given, dvisvgm analyzes the actual shape of each character and derives a usually tight bounding box\&. +.RE +.PP +\fB\-m, \-\-fontmap\fR=\fIfilenames\fR +.RS 4 +Loads and evaluates a single or multiple font map files\&. These files are required to resolve font file names and encodings\&. dvisvgm does not provide its own map files but tries to read available ones coming with dvips or dvipdfm\&. If option +\fB\-\-fontmap\fR +is omitted, dvisvgm looks for the default map files +ps2pk\&.map, +dvipdfm\&.map, and +psfonts\&.map +(in this order)\&. Otherwise, the listed files are used\&. Multiple filenames must be separated by commas without leading and/or trailing whitespace\&. The map files are evaluated in the given order\&. By default, redefined mappings do not replace previous ones\&. However, each filename can be preceded by an optional mode specifier (\fB+\fR, +\fB\-\fR, or +\fB=\fR) to change this behavior: +.PP ++mapfile +.RS 4 +Only those entries in the given map file that don\(cqt redefine a font mapping are applied\&. That\(cqs also the default mode if no mode specifier is given\&. +.RE +.PP +\-mapfile +.RS 4 +Ensures that none of the font mappings defined in the given map file are used, i\&.e\&. previously defined mappings for the specified fonts are removed\&. +.RE +.PP +=mapfile +.RS 4 +All mappings defined in the map file are applied\&. Previously defined settings for the same font are replaced\&. +.sp +If the first filename in the filename sequence is preceded by a mode specifier, dvisvgm loads the default font map (see above) and applies the other map files afterwards\&. Otherwise, none of default map files will be loaded automatically\&. +.sp +Examples: +\fB\-\-fontmap=myfile1\&.map,+myfile2\&.map\fR +loads +myfile1\&.map +followed by +myfile2\&.map +where all redefinitions of +myfile2\&.map +are ignored\&. +\fB\-\-fontmap==myfile1\&.map,\-myfile2\&.map\fR +loads the default map file followed by +myfile1\&.map +and +myfile2\&.map +where all redefinitions of +myfile1\&.map +replace previous entries\&. Afterwards, all definitions for the fonts given in +myfile2\&.map +are removed from the font map tree\&. +.sp +For further information about the map file formats and the mode specifiers, see the manuals of dvips and dvipdfm\&. +.RE +.RE +.PP +\fB\-\-grad\-overlap\fR +.RS 4 +Tells dvisvgm to create overlapping grid segments when approximating color gradient fills (also see option +\fB\-\-grad\-segments\fR +below)\&. By default, adjacent segments don\(cqt overlap but only touch each other like separate tiles\&. Unfortunately, this alignment can lead to visible gaps between the segments because the background influences the color at the boundary of the segments if the SVG renderer uses anti\-aliasing to create smooth contours\&. One way to avoid this and to create seamlessly touching color regions is to enlarge the segments so that they extent into the area of their right and bottom neighbors\&. Since the latter are drawn on top of the overlapping parts, the visible size of all segments keeps unchanged\&. Just the former gaps disappear as the background is now completely covered by the correct colors\&. Currently, dvisvgm computes the overlapping segments separately for each patch of the mesh (a patch mesh may consist of multiple patches of the same type)\&. Therefore, there still might be visible gaps at the seam of two adjacent patches\&. +.RE +.PP +\fB\-\-grad\-segments\fR=\fInumber\fR +.RS 4 +Determines the maximal number of segments per column and row used to approximate gradient color fills\&. Since SVG 1\&.1 only supports a small subset of the shading algorithms available in PostScript, dvisvgm approximates some of them by subdividing the area to be filled into smaller, monochromatic segments\&. Each of these segments gets the average color of the region it covers\&. Thus, increasing the number of segments leads to smaller monochromatic areas and therefore results in a better approximation of the actual color gradient\&. As a drawback, more segments imply bigger SVG files because every segment is represented by a separate path element\&. +.sp +Currently, dvisvgm supports free\- and lattice\-form triangular patch meshes as well as Coons and tensor\-product patch meshes\&. They are approximated by subdividing the area of each patch into a +\fIn\fR\(mu\fIn\fR +grid of smaller segments\&. The maximal number of segments per column and row can be changed with option +\fB\-\-grad\-segments\fR\&. +.RE +.PP +\fB\-\-grad\-simplify\fR=\fIdelta\fR +.RS 4 +If the size of the segments created to approximate gradient color fills falls below the given delta value, dvisvgm reduces their level of detail\&. For example, Bézier curves are replaced by straight lines, and triangular segments are combined to tetragons\&. For a small delta these simplifications are usually not noticeable but reduce the size of the generated SVG files\&. +.RE +.PP +\fB\-h, \-\-help\fR[=\fImode\fR] +.RS 4 +Prints a short summary of all available command\-line options\&. The optional +\fImode\fR +parameter is an integer value between 0 and 2\&. It selects the display variant of the help text\&. Mode 0 lists all options divided into categories with section headers\&. This is also the default if dvisvgm is called without parameters\&. Mode 1 lists all options ordered by the short option names, while mode 2 sorts the lines by the long option names\&. +.RE +.PP +\fB\-\-keep\fR +.RS 4 +Disables the removal of temporary files as created by Metafont (usually \&.gf, \&.tfm, and \&.log files)\&. +.RE +.PP +\fB\-\-libgs\fR=\fIfilename\fR +.RS 4 +This option is only available if the Ghostscript library is not directly linked to dvisvgm and if PostScript support was not completely disabled during compilation\&. In this case, dvisvgm tries to load the shared GS library dynamically during runtime\&. By default, it expects the library\(cqs name to be libgs\&.so\&.X (on Unix\-like systems, where X is the ABI version of the library) or gsdll32\&.dll/gsdll64\&.dll (Windows)\&. Option +\fB\-\-libgs\fR +can be used to give a different name\&. Alternatively, it\(cqs also possible to set the GS library name by the environment variable +LIBGS\&. The latter has less precedence than the command\-line option, i\&.e\&. dvisvgm ignores variable +LIBGS +if +\fB\-\-libgs\fR +is given\&. +.RE +.PP +\fB\-L, \-\-linkmark\fR=\fIstyle\fR +.RS 4 +Selects the method how to mark hyperlinked areas\&. The +\fIstyle\fR +argument can take one of the values +\fInone\fR, +\fIbox\fR, and +\fIline\fR, where +\fIbox\fR +is the default, i\&.e\&. a rectangle is drawn around the linked region if option +\fB\-\-linkmark\fR +is omitted\&. Style argument +\fIline\fR +just draws the lower edge of the bounding rectangle, and +\fInone\fR +tells dvisvgm not to add any visible objects to hyperlinks\&. The lines and boxes get the current text color selected\&. In order to apply a different, constant color, a colon followed by a color specifier can be appended to the style string\&. A +\fIcolor specifier\fR +is either a hexadecimal RGB value of the form +\fI#RRGGBB\fR, or a dvips color name as listed here: +http://en\&.wikibooks\&.org/wiki/LaTeX/Colors#The_68_standard_colors_known_to_dvips +.sp +Moreover, argument +\fIstyle\fR +can take a single color specifier to highlight the linked region by a frameless box filled with that color\&. An optional second color specifier separated by colon selects the frame color\&. +.sp +Examples: +\fBbox:red\fR +or +\fBbox:#ff0000\fR +draws red boxes around the linked areas\&. +\fByellow:blue\fR +creates yellow filled rectangles with blue frames\&. +.RE +.PP +\fB\-l, \-\-list\-specials\fR +.RS 4 +Prints a list of registered special handlers and exits\&. Each handler processes a set of special statements belonging to the same category\&. In most cases, the categories are identified by the prefix of the special statements\&. It\(cqs usually a leading word separated from the rest of the statement by a colon or a blank, e\&.g\&. +\fIcolor\fR +or +\fIps\fR\&. +.RE +.PP +\fB\-M, \-\-mag\fR=\fIfactor\fR +.RS 4 +Sets the magnification factor applied in conjunction with 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\&. +.RE +.PP +\fB\-\-no\-merge\fR +.RS 4 +Puts every single character in a separate +\fItext\fR +element with corresponding +\fIx\fR +and +\fIy\fR +attributes\&. By default, new +\fItext\fR +or +\fItspan\fR +elements are only created if a string starts at a location that differs from the regular position defined by the characters\*(Aq advance values\&. +.RE +.PP +\fB\-\-no\-mktexmf\fR +.RS 4 +Suppresses the generation of missing font files\&. If dvisvgm can\(cqt find a font file through the kpathsea lookup mechanism, it calls the external tools mktextfm or mktexmf by\&. This option disables these calls\&. +.RE +.PP +\fB\-n, \-\-no\-fonts\fR[=\fIvariant\fR] +.RS 4 +If this option is given, dvisvgm doesn\(cqt create SVG +\fIfont\fR +elements but uses +\fIpaths\fR +instead\&. The resulting SVG files tend to be larger but they are concurrently more compatible with most applications that don\(cqt support SVG fonts yet\&. The optional argument +\fIvariant\fR +selects the method how to substitute fonts by paths\&. Variant 0 creates +\fIpath\fR +and +\fIuse\fR +elements\&. Variant 1 creates +\fIpath\fR +elements only\&. Option +\fB\-\-no\-fonts\fR +implies +\fB\-\-no\-styles\fR\&. +.RE +.PP +\fB\-c, \-\-scale\fR=\fIsx\fR[,\fIsy\fR] +.RS 4 +Scales the page content horizontally by +\fIsx\fR +and vertically by +\fIsy\fR\&. This option is equivalent to +\fB\-TS\fR\fIsx\fR,\fIsy\fR\&. +.RE +.PP +\fB\-S, \-\-no\-specials\fR[=\fInames\fR] +.RS 4 +Disable processing of special commands 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 +\fIname\fR +is the unique identifier referencing the intended special handler\&. Option +\fB\-\-list\-specials\fR +lists all currently available handlers and their names\&. All unsupported special statements are silently ignored\&. +.RE +.PP +\fB\-\-no\-styles\fR +.RS 4 +By default, dvisvgm creates CSS styles and class attributes to reference fonts because it\(cqs 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 +\fB\-\-no\-styles\fR\&. +.RE +.PP +\fB\-o, \-\-output\fR=\fIpattern\fR +.RS 4 +Sets the name pattern of the output file\&. 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\&. The default 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 Windows environments, the percent sign indicates dereferenced environment variables, and must therefore be protected by a second percent sign, e\&.g\&. +\fB\-\-output=%%f\-%%p\fR\&. +.RE +.PP +\fB\-p, \-\-page\fR=\fIranges\fR +.RS 4 +This option sets the pages to be processed\&. Parameter +\fIranges\fR +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\(cqt 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 +\fB\-\-page\fR +is omitted\&. 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\&. Please consider that the page values don\(cqt refer to the page numbers printed on the page\&. Instead, the physical page count is expected, where the first page always gets number 1\&. +.RE +.PP +\fB\-d, \-\-precision\fR=\fIdigits\fR +.RS 4 +Specifies the maximal number of decimal places applied to floating\-point attribute values\&. All attribute values written to the generated SVG file(s) are rounded accordingly\&. The parameter +\fIdigits\fR +allows integer values from 0 to 6, where 0 enables the automatic selection of significant decimal places\&. This is also the default value if dvisvgm is called without option +\fB\-\-precision\fR\&. +.RE +.PP +\fB\-P, \-\-progress\fR[=\fIdelay\fR] +.RS 4 +Enables a simple progress indicator shown when time\-consuming operations like PostScript specials are processed\&. The indicator doesn\(cqt appear before the given delay (in seconds) has elapsed\&. The default delay value is 0\&.5 seconds\&. +.RE +.PP +\fB\-r, \-\-rotate\fR=\fIangle\fR +.RS 4 +Rotates the page content clockwise by +\fIangle\fR +degrees around the page center\&. This option is equivalent to +\fB\-TR\fR\fIangle\fR\&. +.RE +.PP +\fB\-R, \-\-relative\fR +.RS 4 +SVG allows to define graphics paths by a sequence of absolute and/or relative commands, i\&.e\&. each command expects either absolute coordinates or coordinates relative to the current drawing position\&.

The evaluation of special commands is delegated to dedicated handlers\&. 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 \fB\-\-list\-specials\fR (see above)\&. This section gives an overview of the special commands currently supported\&. +.PP +\fBbgcolor\fR +.RS 4 +Special statement for changing the background/page color\&. Since SVG 1\&.1 doesn\(cqt support background colors, dvisvgm inserts a rectangle of the chosen color into the generated SVG document\&. This rectangle always gets the same size as the selected or computed bounding box\&. This background color 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\&. +.RE +.PP +\fBcolor\fR +.RS 4 +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\&. +.RE +.PP +\fBdvisvgm\fR +.RS 4 +dvisvgm offers its own small set of specials\&. The following list gives a brief overview\&. +.PP +\fBdvisvgm:raw\fR \fItext\fR +.RS 4 +Adds an arbitrary sequence of characters to the page section of the SVG document\&. dvisvgm does not perform any validation here, thus the user has to ensure that the resulting SVG is still valid\&. Parameter +\fItext\fR +may contain the expressions +\fB{?x}\fR, +\fB{?y}\fR, and +\fB{?color}\fR +that expand to the current +\fIx\fR +or +\fIy\fR +coordinate and the current color, respectively\&. Furthermore, +\fB{?nl}\fR +expands to a newline character\&. +.RE +.PP +\fBdvisvgm:rawdef\fR \fItext\fR +.RS 4 +This command is similar to +\fBdvisvgm:raw\fR, but puts the raw text into the section of the SVG document currently being generated\&. +.RE +.PP +\fBdvisvgm:rawset\fR \fIname\fR \&... \fBdvisvgm:endrawset\fR +.RS 4 +This pair of specials marks the begin and end of a definition of a named raw SVG fragment\&. All +\fBdvisvgm:raw\fR +and +\fBdvisvgm:rawdef\fR +specials enclosed by +\fBdvisvgm:rawset\fR +and +\fBdvisvgm:endrawset\fR +are not evaluated immediately but jointly stored under the given +\fIname\fR +for later use\&. Once defined, the named fragment can be referenced throughout the DVI file by +\fBdvisvgm:rawput\fR +(see below)\&. +\fBdvisvgm:rawset\fR +and +\fBdvisvgm:endrawset\fR +must not be nested, i\&.e\&. each call of +\fBdvisvgm:rawset\fR +has to be followed by a corresponding call of +\fBdvisvgm:endrawset\fR +before another +\fBdvisvgm:rawset\fR +may occur\&. Also, the identifier +\fIname\fR +must be unique throughout the DVI file\&. Using +\fBdvisvgm:rawset\fR +multiple times together with the same +\fIname\fR +leads to a warning message\&. +.RE +.PP +\fBdvisvgm:rawput\fR \fIname\fR +.RS 4 +Inserts raw SVG fragments previously stored under the given +\fIname\fR\&. dvisvgm distinguishes between fragments that were specified with +\fBdvisvgm:raw\fR +or +\fBdvisvgm:rawdef\fR, and handles them differently: It inserts all +\fBdvisvgm:raw\fR +parts every time +\fBdvisvgm:rawput\fR +is called, whereas the +\fBdvisvgm:rawdef\fR +portions go to the section of the current SVG document only once\&. +.RE +.PP +\fBdvisvgm:img\fR \fIwidth\fR \fIheight\fR \fIfile\fR +.RS 4 +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 +\fIwidth\fR +and +\fIheight\fR +must be given as plain floating point numbers in TeX point units (1in = 72\&.27pt)\&. +.RE +.PP +\fBdvisvgm:bbox\fR n[ew] \fIname\fR +.RS 4 +Defines or resets a local bounding box called +\fIname\fR\&. 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 +\fB{?bbox \fR\fB\fIname\fR\fR\fB}\fR +expands to the four values +\fIx\fR, +\fIy\fR, +\fIw\fR, and +\fIh\fR +(separated by spaces) specifying the coordinates of the upper left corner, width, and height of the local box +\fIname\fR\&. If box +\fIname\fR +wasn\(cqt previously defined, all four values equal zero\&. +.RE +.PP +\fBdvisvgm:bbox\fR \fIwidth\fR \fIheight\fR [\fIdepth\fR] +.RS 4 +Updates the bounding box of the current page by embedding a virtual rectangle (\fIx\fR, +\fIy\fR, +\fIwidth\fR, +\fIheight\fR) where the lower left corner is located at the current DVI drawing position (\fIx\fR,\fIy\fR)\&. If the optional parameter +\fIdepth\fR +is specified, dvisvgm embeds a second rectangle (\fIx\fR, +\fIy\fR, +\fIwidth\fR, \-\fIdepth\fR)\&. The lengths +\fIwidth\fR, +\fIheight\fR +and +\fIdepth\fR +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\(cqs not possible to reduce its extent\&. This special should be used in conjunction with +\fBdvisvgm:raw\fR +in order to update the viewport of the page properly\&. +.RE +.PP +\fBdvisvgm:bbox\fR a[bs] \fIx1\fR \fIy1\fR \fIx2\fR \fIy2\fR +.RS 4 +This variant of the bbox special updates the bounding box by embedding a virtual rectangle (\fIx1\fR,\fIy1\fR,\fIx2\fR,\fIy2\fR)\&. The points (\fIx1\fR,\fIy1\fR) and (\fIx2\fR,\fIy2\fR) denote two diagonal corners of the rectangle given in TeX point units\&. +.RE +.PP +\fBdvisvgm:bbox\fR f[ix] \fIx1\fR \fIy1\fR \fIx2\fR \fIy2\fR +.RS 4 +This variant of the bbox special assigns an absolute (final) bounding box to the resulting SVG\&. After executing this command, dvisvgm doesn\(cqt further alter the bounding box coordinates, except this special is called again later\&. The points (\fIx1\fR,\fIy1\fR) and (\fIx2\fR,\fIy2\fR) denote two diagonal corners of the rectangle given in TeX point units\&. +.sp +The following TeX snippet adds two raw SVG elements to the output and updates the bounding box accordingly: +.sp +.if n \{\ +.RS 4 +.\} +.nf +\especial{dvisvgm:raw } +\especial{dvisvgm:bbox 20 10 10} + +\especial{dvisvgm:raw } +\especial{dvisvgm:bbox abs 10 200 100 250} +.fi +.if n \{\ +.RE +.\} +.RE +.RE +.PP +\fBem\fR +.RS 4 +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 and ignores all other em specials silently\&. A description of the command syntax can be found in the DVI driver documentation coming with emTeX (see CTAN)\&. +.RE +.PP +\fBhtml\fR +.RS 4 +The hyperref specification defines several variants on how to mark hyperlinked areas in a DVI file\&. dvisvgm supports the plain HyperTeX special constructs as created with hyperref package option +\fIhypertex\fR\&. By default, all linked areas of the document are marked by a rectangle\&. Option +\fB\-\-linkmark\fR +allows to change this behavior\&. See above for further details\&. Information on syntax and semantics of the HyperTeX specials can be found in the hyperref manual\&. +.RE +.PP +\fBpdf\fR +.RS 4 +pdfTeX and dvipdfmx introduced several special commands related to the generation of PDF files\&. Currently, only two of them, +\fIpdf:mapfile\fR +and +\fIpdf:mapline\fR +are supported by dvisvgm\&. These specials allow modifying the font map tree during the processing of DVI files\&. They are used by CTeX, for example\&. dvisvgm supports both, the dvips and dvipdfm font map format\&. For further information on the command syntax and semantics, see the documentation of \epdfmapfile in the pdfTeX user manual\&. +.RE +.PP +\fBps\fR +.RS 4 +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 all PostScript snippets and to convert as many of them as possible to SVG\&. In contrast to dvips, dvisvgm uses floating point arithmetics to compute the precise position of each graphic element, i\&.e\&. it doesn\(cqt round the coordinates\&. Therefore, the relative locations of the graphic elements may slightly differ from those computed by dvips\&. +.sp +Since PostScript is a rather complex language, dvisvgm does not try to implement its own PostScript interpreter but relies on Ghostscript instead\&. If the Ghostscript library was not linked to the dvisvgm binary, it is looked up and loaded dynamically during runtime\&. In this case, dvisvgm looks for +\fIlibgs\&.so\&.X\fR +on Unix\-like systems (supported ABI versions: 7,8,9), and for +\fIgsdll32\&.dll\fR +or +\fIgsdll64\&.dll\fR +on Windows\&. You can override the default file names with environment variable +LIBGS +or the command\-line option +\fB\-\-libgs\fR\&. The library must be reachable through the ld search path (*nix) or the PATH environment variable (Windows)\&. Alternatively, the absolute file path can be specified\&. If the library cannot be found, dvisvgm disables the processing of PostScript specials and prints a warning message\&. Use option +\fB\-\-list\-specials\fR +to check whether PostScript support is available, i\&.e\&. entry +\fIps\fR +is present\&. +.sp +The PostScript handler also recognizes and evaluates bounding box data generated by the +\fIpreview\fR +package with option +\fItightpage\fR\&. If the data is present in a DVI file, dvisvgm adapts the bounding box of the generated SVG file accordingly, and prints a message showing the width, height, and depth of the box in TeX point units\&. Especially, the depth value can be used to vertically align the SVG graphics with the baseline of surrounding text in HTML or XSL\-FO documents, for example\&. +.RE +.PP +\fBtpic\fR +.RS 4 +The TPIC special set defines instructions for drawing simple geometric objects\&. Some LaTeX packages, like eepic and tplot, use these specials to describe graphics\&. +.RE +.SH "EXAMPLES" +.sp +.if n \{\ +.RS 4 +.\} +.nf +dvisvgm file +.fi +.if n \{\ +.RE +.\} +.sp +Converts the first page of \fIfile\&.dvi\fR to \fIfile\&.svg\fR\&. +.sp +.if n \{\ +.RS 4 +.\} +.nf +dvisvgm \-z file +.fi +.if n \{\ +.RE +.\} +.sp +Converts the first page of \fIfile\&.dvi\fR to \fIfile\&.svgz\fR with default compression level 9\&. +.sp +.if n \{\ +.RS 4 +.\} +.nf +dvisvgm \-p5 \-z3 \-ba4\-l \-onewfile file +.fi +.if n \{\ +.RE +.\} +.sp +Converts the fifth page of \fIfile\&.dvi\fR to \fInewfile\&.svgz\fR with compression level 3\&.

The environment variable LIBGS can be used to specify path and file name of the library\&. +.sp +The pre\-compiled Windows versions of dvisvgm require a working installation of MiKTeX 2\&.9 or above\&. dvisvgm does not work together with the portable edition of MiKTeX because it relies on MiKTeX\(cqs COM interface only accessible in a local installation\&. To enable the evaluation of PostScript specials, the original Ghostscript DLL \fIgsdll32\&.dll\fR must be present and reachable through the search path\&. 64\-bit Windows builds require the 64\-bit Ghostscript DLL \fIgsdll64\&.dll\fR\&.

It supports the classic DVI format 2 as +well as format 3 (created by pTeX in vertical mode), and format 5 which is also known as +XDV (created by XeTeX). Besides the basic DVI commands, dvisvgm also evaluates many so-called +'specials' which heavily extend the capabilities of the DVI format. For a more detailed +overview, see section *support of specials* below. + +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. + +SVG is a vector-based graphics format and therefore dvisvgm tries to convert the glyph outlines +of all used fonts to scalable path descriptions. The fastest way to do that is to extract the +path information from font files in PFB, TTF, or OTF format. If dvisvgm is able to find such +a file, it extracts all necessary outline information about the glyphs from it. + +However, TeX's main source for font descriptions is Metafont, which produces bitmap output +(GF files). That's why not all obtainable TeX fonts are available in a scalable format. +In these cases, dvisvgm tries to vectorize Metafont's output by tracing the glyph bitmaps. +The results are not as perfect as most (manually optimized) PFB or OTF counterparts, but are +nonetheless really nice in most cases. + +When running dvisvgm without option *--no-fonts*, 'font' elements (...) are used to +embed the font data into the SVG files. Unfortunately, only few SVG renderes support these +elements yet. Most web browsers and vector graphics applications don't evaluate them properly +so that the text components of the resulting graphics might look strange. In order to create +more compatible SVG files, command-line option *--no-fonts* can be given to replace the font +elements by plain graphics paths. + + +OPTIONS +------- +*-a, --trace-all*=['retrace']:: +This option forces dvisvgm to trace not only 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 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*::: page size stored in the DVI file + *min*::: computes the minimal/tightest bounding box + *none*::: no bounding box is 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 size specifier 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, --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/cache. 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 together with further information about the stored fonts. +Additionally, outdated and corrupted cache files are removed. + + +*-j, --clipjoin*:: +This option tells dvisvgm to compute the intersection of clipping paths itself if necessary, +and not to delegate this task to the SVG renderer. The resulting SVG files are more portable +because some SVG renderers don't support intersections of clipping paths which are defined by +'clipPath' elements that contain a 'clip-path' attribute. + + +*--color*:: +Enables colorization of messages printed during the conversion process. The colors can be customized +via the environment variable +DVISVGM_COLORS+. See the ENVIRONMENT section below for further information. + + +*-E, --eps*:: +If this option is given, dvisvgm does not expect a DVI but an EPS input file, and tries to convert +it to SVG. In order to do so, a single 'psfile' special command is created and forwarded to the +PostScript special handler. +This option is only available if dvisvgm was built with PostScript support enabled, and requires +Ghostscript to be available. See option *--libgs* for further information. + + +*-e, --exact*:: +If this option is given, dvisvgm computes the precise bounding box of each character. By default, +the values stored in a font's TFM file are used to determine a glyph's extent. As these values are +intended to implement 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, width +and/or height of some glyphs may be larger (or smaller) than the respective TFM values. As a result, +this can lead to clipped characters at the bounds of the SVG graphics. With option *--exact* given, +dvisvgm analyzes the actual shape of each character and derives a usually tight bounding box. + + +*-m, --fontmap*='filenames':: +Loads and evaluates a single or multiple font map files. These files are required to resolve +font file names and encodings. dvisvgm does not provide its own map files but tries to read +available ones coming with dvips or dvipdfm. If option *--fontmap* is omitted, dvisvgm looks for the +default map files +ps2pk.map+, +dvipdfm.map+, and +psfonts.map+ (in this order). Otherwise, the +listed files are used. Multiple filenames must be separated by commas without leading and/or trailing +whitespace. +The map files are evaluated in the given order. By default, redefined mappings do not replace previous ones. +However, each filename can be preceded by an optional mode specifier (*+*, *-*, or *=*) to change this behavior: + + +mapfile;; + Only those entries in the given map file that don't redefine a font mapping are applied. + That's also the default mode if no mode specifier is given. + + -mapfile;; + Ensures that none of the font mappings defined in the given map file are used, i.e. previously + defined mappings for the specified fonts are removed. + + =mapfile;; + All mappings defined in the map file are applied. Previously defined settings for the same font + are replaced. ++ +If the first filename in the filename sequence is preceded by a mode specifier, dvisvgm loads the +default font map (see above) and applies the other map files afterwards. Otherwise, none of default +map files will be loaded automatically. ++ +Examples: *--fontmap=myfile1.map,+myfile2.map* loads `myfile1.map` followed by `myfile2.map` where all +redefinitions of `myfile2.map` are ignored. +*--fontmap==myfile1.map,-myfile2.map* loads the default map file followed by `myfile1.map` and `myfile2.map` +where all redefinitions of `myfile1.map` replace previous entries. Afterwards, all definitions for the fonts +given in `myfile2.map` are removed from the font map tree. ++ +For further information about the map file formats and the mode specifiers, see the manuals of dvips and dvipdfm. + + +*--grad-overlap*:: +Tells dvisvgm to create overlapping grid segments when approximating color gradient fills (also see +option *--grad-segments* below). By default, adjacent segments don't overlap but only touch each other +like separate tiles. Unfortunately, this alignment can lead to visible gaps between the segments +because the background influences the color at the boundary of the segments if the SVG renderer uses +anti-aliasing to create smooth contours. +One way to avoid this and to create seamlessly touching color regions is to enlarge the segments so +that they extent into the area of their right and bottom neighbors. Since the latter are drawn on top +of the overlapping parts, the visible size of all segments keeps unchanged. Just the former gaps +disappear as the background is now completely covered by the correct colors. +Currently, dvisvgm computes the overlapping segments separately for each patch of the mesh (a patch mesh +may consist of multiple patches of the same type). Therefore, there still might be visible gaps +at the seam of two adjacent patches. + + +*--grad-segments*='number':: +Determines the maximal number of segments per column and row used to approximate gradient color fills. +Since SVG 1.1 only supports a small subset of the shading algorithms available in PostScript, +dvisvgm approximates some of them by subdividing the area to be filled into smaller, monochromatic +segments. Each of these segments gets the average color of the region it covers. Thus, increasing the +number of segments leads to smaller monochromatic areas and therefore results in a better approximation +of the actual color gradient. As a drawback, more segments imply bigger SVG files because every +segment is represented by a separate path element. ++ +Currently, dvisvgm supports free- and lattice-form triangular patch meshes as well as Coons and +tensor-product patch meshes. They are approximated by subdividing the area of each patch into a +__n__×__n__ grid of smaller segments. The maximal number of segments per column and row can be +changed with option *--grad-segments*. + + +*--grad-simplify*='delta':: +If the size of the segments created to approximate gradient color fills falls below the given delta +value, dvisvgm reduces their level of detail. For example, Bézier curves are replaced by straight +lines, and triangular segments are combined to tetragons. For a small delta these simplifications +are usually not noticeable but reduce the size of the generated SVG files. + + +*-h, --help*[='mode']:: +Prints a short summary of all available command-line options. The optional 'mode' parameter is +an integer value between 0 and 2. It selects the display variant of the help text. Mode 0 +lists all options divided into categories with section headers. This is also the default if +dvisvgm is called without parameters. Mode 1 lists all options ordered by the short option names, +while mode 2 sorts the lines by the long option names. + + +*--keep*:: +Disables the removal of temporary files as created by Metafont (usually .gf, .tfm, and .log files). + + +*--libgs*='filename':: +This option is only available if the Ghostscript library is not directly linked to dvisvgm and if +PostScript support was not completely disabled during compilation. 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.X (on Unix-like systems, where X is the ABI version of the library) or +gsdll32.dll/gsdll64.dll (Windows). Option *--libgs* can be used to give a different name. +Alternatively, it's also possible to set the GS library name by the environment variable +LIBGS+. +The latter has less precedence than the command-line option, i.e. dvisvgm ignores variable +LIBGS+ +if *--libgs* is given. + + +*-L, --linkmark*='style':: +Selects the method how to mark hyperlinked areas. The 'style' argument can take one of the values +'none', 'box', and 'line', where 'box' is the default, i.e. a rectangle is drawn around +the linked region if option *--linkmark* is omitted. Style argument 'line' just draws the lower edge of +the bounding rectangle, and 'none' tells dvisvgm not to add any visible objects to hyperlinks. +The lines and boxes get the current text color selected. In order to apply a different, constant color, +a colon followed by a color specifier can be appended to the style string. A 'color specifier' is either +a hexadecimal RGB value of the form '#RRGGBB', or a dvips color name as listed here: +http://en.wikibooks.org/wiki/LaTeX/Colors#The_68_standard_colors_known_to_dvips ++ +Moreover, argument 'style' can take a single color specifier to highlight the linked region by +a frameless box filled with that color. An optional second color specifier separated by colon +selects the frame color. ++ +Examples: *box:red* or *box:#ff0000* draws red boxes around the linked areas. *yellow:blue* creates +yellow filled rectangles with blue frames. + + +*-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. In most cases, 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'. + + +*-M, --mag*='factor':: +Sets the magnification factor applied in conjunction with 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. + + +*--no-merge*:: +Puts every single character in a separate 'text' element with corresponding 'x' and 'y' attributes. +By default, new 'text' or 'tspan' elements are only created if a string starts at a location that +differs from the regular position defined by the characters' advance values. + + +*--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. +This option disables these calls. + + +*-n, --no-fonts*[='variant']:: +If this option is given, dvisvgm doesn't create SVG 'font' elements but uses 'paths' instead. The +resulting SVG files tend to be larger but they are concurrently more compatible with most applications that +don't support SVG fonts yet. The optional argument 'variant' selects the method how to substitute fonts +by paths. Variant 0 creates 'path' and 'use' elements. Variant 1 creates 'path' elements only. +Option *--no-fonts* implies *--no-styles*. + + +*-c, --scale*='sx'[,'sy']:: +Scales the page content horizontally by 'sx' and vertically by 'sy'. This option is equivalent +to *-TS*'sx','sy'. + + +*-S, --no-specials*[='names']:: +Disable processing of special commands 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 the unique +identifier referencing the intended 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 creates 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*. + + +*-o, --output*='pattern':: +Sets the name pattern of the output file. 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. +The default 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 indicates dereferenced 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 omitted. +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. + + +*-d, --precision*='digits':: +Specifies the maximal number of decimal places applied to floating-point attribute values. +All attribute values written to the generated SVG file(s) are rounded accordingly. The +parameter 'digits' allows integer values from 0 to 6, where 0 enables the automatic selection +of significant decimal places. This is also the default value if dvisvgm is called without +option *--precision*. + + +*-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) has elapsed. The default delay value is 0.5 seconds. + + +*-r, --rotate*='angle':: +Rotates the page content clockwise by 'angle' degrees around the page center. +This option is equivalent to *-TR*'angle'. + + +*-R, --relative*:: +SVG allows to define graphics paths by a sequence of absolute and/or relative commands, +i.e. each command expects either absolute coordinates or coordinates relative to the +current drawing position. By default, dvisvgm creates paths made up of absolute commands. +If option *--relative* is given, relative commands are created instead which slightly reduces +the size of the SVG files in most cases. + + +*-s, --stdout*:: +Don't write the SVG output to a file but redirect it to *stdout*. + + +*-T, --transform*='commands':: +Applies a sequence of transformations to the SVG content. Each transformation is described +by a 'command' beginning with a capital letter followed by a list of comma-separated +parameters. Following transformation commands are supported: + + *T* 'tx'[,'ty'];; + Translates (moves) the 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 the page horizontally by 'sx' and vertically by 'sy'. If 'sy' is omitted, + 'sy'='sx' is assumed. + + *R* 'angle'[,'x','y'];; + Rotates the 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 the 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 the 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) the 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) the 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), *-* (subtraction), +*** (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. + +================================================================================================= ++ +// + +// +*-t, --translate*='tx'[,'ty']:: +Translates (moves) the page content in direction of vector ('tx','ty'). This option is +equivalent to *-TT*'tx','ty'. + + +*-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*[='extended']:: +Prints the version of dvisvgm and exits. If the optional argument is set to 'yes', the +version numbers of the linked libraries are printed as well. + + +*-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 value is 9). Larger values cause better +compression results but take more computation time. ++ +CAUTION: This option cannot be combined with *-s, --stdout*. + + +*-Z, --zoom*[='factor']:: +Multiplies the 'width' and 'height' attributes of the SVG root element by argument 'factor' while +the coordinate system of the graphic is retained. As a result, most SVG viewers zoom the graphics +accordingly. If a negative zoom factor is given, the 'width' and 'height' attributes are omitted. + + +SUPPORT OF SPECIALS +------------------- +dvisvgm supports several sets of 'special commands' that can be used to enrich DVI files with additional +features, like color, graphics, and hyperlinks. The evaluation of special commands is delegated to dedicated +handlers. 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). This section gives an overview of the special commands currently supported. + +*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 into the generated SVG document. This rectangle always gets +the same size as the selected or computed bounding box. This background color 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 page section of the SVG document. dvisvgm does not perform + any validation here, thus the user has to ensure that the resulting SVG is still valid. Parameter 'text' + may contain the expressions *{?x}*, *{?y}*, and *{?color}* that expand to the current 'x' or 'y' coordinate + and the current color, respectively. Furthermore, *{?nl}* expands to a newline character. + + *dvisvgm:rawdef* 'text';; + This command is similar to *dvisvgm:raw*, but puts the raw text into the section of the SVG document + currently being generated. + + *dvisvgm:rawset* 'name' ... *dvisvgm:endrawset*;; + This pair of specials marks the begin and end of a definition of a named raw SVG fragment. All *dvisvgm:raw* + and *dvisvgm:rawdef* specials enclosed by *dvisvgm:rawset* and *dvisvgm:endrawset* are not evaluated + immediately but jointly stored under the given 'name' for later use. Once defined, the named fragment can be + referenced throughout the DVI file by *dvisvgm:rawput* (see below). + *dvisvgm:rawset* and *dvisvgm:endrawset* must not be nested, i.e. each call of *dvisvgm:rawset* has to be + followed by a corresponding call of *dvisvgm:endrawset* before another *dvisvgm:rawset* may occur. + Also, the identifier 'name' must be unique throughout the DVI file. Using *dvisvgm:rawset* multiple times + together with the same 'name' leads to a warning message. + + *dvisvgm:rawput* 'name';; + Inserts raw SVG fragments previously stored under the given 'name'. dvisvgm distinguishes between fragments + that were specified with *dvisvgm:raw* or *dvisvgm:rawdef*, and handles them differently: It inserts all + *dvisvgm:raw* parts every time *dvisvgm:rawput* is called, whereas the *dvisvgm:rawdef* portions go to the + section of the current SVG document only once. + + *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 update the viewport + of the page properly. + + *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 and ignores all other em specials silently. +A description of the command syntax can be found in the DVI driver documentation coming with emTeX (see CTAN). + +*html*:: +The hyperref specification defines several variants on how to mark hyperlinked areas in a DVI file. dvisvgm +supports the plain HyperTeX special constructs as created with hyperref package option 'hypertex'. +By default, all linked areas of the document are marked by a rectangle. Option *--linkmark* allows to change +this behavior. See above for further details. Information on syntax and semantics of the HyperTeX specials can be +found in the hyperref manual. + +*pdf*:: +pdfTeX and dvipdfmx introduced several special commands related to the generation of PDF files. Currently, only +two of them, 'pdf:mapfile' and 'pdf:mapline' are supported by dvisvgm. These specials allow modifying the font map +tree during the processing of DVI files. They are used by CTeX, for example. dvisvgm supports both, the dvips and +dvipdfm font map format. For further information on the command syntax and semantics, see the documentation of +\pdfmapfile in the pdfTeX user manual. + +*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 all +PostScript snippets and to convert as many of them as possible to SVG. In contrast to dvips, dvisvgm uses +floating point arithmetics to compute the precise position of each graphic element, i.e. it doesn't round the +coordinates. Therefore, the relative locations of the graphic elements may slightly differ from those computed +by dvips. ++ +Since PostScript is a rather complex language, dvisvgm does not try to implement its own PostScript interpreter +but relies on Ghostscript instead. If the Ghostscript library was not linked to the dvisvgm binary, it is looked up +and loaded dynamically during runtime. In this case, dvisvgm looks for 'libgs.so.X' on Unix-like systems +(supported ABI versions: 7,8,9), and for 'gsdll32.dll' or 'gsdll64.dll' on Windows. +You can override the default file names with environment variable +LIBGS+ or the command-line option *--libgs*. +The library must be reachable through the ld search path (\*nix) or the PATH environment variable (Windows). +Alternatively, the absolute file path can be specified. If the library cannot be found, dvisvgm disables the +processing of PostScript specials and prints a warning message. +Use option *--list-specials* to check whether PostScript support is available, i.e. entry 'ps' is present. ++ +The PostScript handler also recognizes and evaluates bounding box data generated by the 'preview' package with +option 'tightpage'. If the data is present in a DVI file, dvisvgm adapts the bounding box of the generated SVG file +accordingly, and prints a message showing the width, height, and depth of the box in TeX point units. Especially, +the depth value can be used to vertically align the SVG graphics with the baseline of surrounding text in HTML +or XSL-FO documents, for example. + +*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 the first page of 'file.dvi' to 'file.svg'. + +--------------- +dvisvgm -z file +--------------- +Converts the first page of 'file.dvi' to 'file.svgz' with default compression level 9. + +------------------------------------- +dvisvgm -p5 -z3 -ba4-l -onewfile file +------------------------------------- +Converts the 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 the 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 if PostScript support has not been disabled, +the shared Ghostscript library is looked up during runtime via dlopen(). The environment variable +LIBGS+ +can be used to specify path and file name of the library. + +The pre-compiled Windows versions of dvisvgm require a working installation of MiKTeX 2.9 or above. +dvisvgm does not work together with the portable edition of MiKTeX because it relies on MiKTeX's COM +interface only accessible in a local installation. +To enable the evaluation of PostScript specials, the original Ghostscript DLL 'gsdll32.dll' must be present +and reachable through the search path. 64-bit Windows builds require the 64-bit Ghostscript DLL 'gsdll64.dll'. +Both DLLs come with the corresponding Ghostscript installers available from www.ghostscript.com. + +The environment variable +DVISVGM_COLORS+ specifies the colors used to highlight various parts of dvisvgm's +message output. It is only evaluated if option *--color* is given. The value of +DVISVGM_COLORS+ is a list of +colon-separated entries of the form 'gg'='BF', where 'gg' denotes one of the color group indicators listed +below, and 'BF' are two hexadecimal digits specifying the background (first digit) and foreground/text color +(second digit). The color values are defined as follows: 0=black, 1=red, 2=green, 3=yellow, 4=blue, +5=magenta, 6=cyan, 7=gray, 8=bright red, 9=bright green, A=bright yellow, B=bright blue, C=bright magenta, +D=bright cyan, E=bright gray, F=white. Depending on the terminal, the colors may differ. Rather than changing +both the text and background color, it's also possible to change only one of them: An asterisk (*) in +place of a hexadecimal digit indicates the default text or background color of the terminal. + +All malformed entries in the list are silently ignored. + +[horizontal] +*er*:: error messages +*wn*:: warning messages +*pn*:: messages about page numbers +*ps*:: page size messages +*fw*:: information about the files written +*sm*:: state messages +*tr*:: messages of the glyph tracer +*pi*:: progress indicator + +*Example:* +er=01:pi=\*5+ sets the colors of error messages (+er+) to red (+1+) on black (+0+), and those +of progress indicators (+pi+) to cyan (+5+) on default background (+*+). + +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 + + +BUGS +---- +Please report bugs using the bug tracker at Launchpad (see https://launchpad.net/dvisvgm). + + +AUTHOR +------ +Written by {author} <{email}> + + +COPYING +------- +Copyright (C) 2005-2014 Martin Gieseking.
