COPYING000064400000043110152526326530005607 0ustar00 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) 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 this service 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 make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. 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. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. 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 Program or any portion of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, 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 Program, 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 Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) 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; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, 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 executable. However, as a special exception, the source code 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. If distribution of executable or 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 counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program 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. 5. 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 Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program 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 to this License. 7. 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 Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program 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 Program. 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. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program 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. 9. The Free Software Foundation may publish revised and/or new versions of the 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 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 Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, 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 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. 12. 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 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. 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 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 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 2 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, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision 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, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This 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 Library General Public License instead of this License.

(It is now possible to build libwmf without any device layers, but this has not been tested extensively and is not recommended for general use.) Special thanks to Bob Friesenhahn, Leonard Rosenthol, David C Sterratt and Tomasz Kłoczko. Hopefully this release will build on Solaris. My apologies to everyone who had problems with libwmf-0.2.1. libwmf-0.2.1 Release Notes -------------------------- In adherence with the ancient philosophy of `It's my birthday and I'll release if I want to,' today, August 22nd 2001, sees the release of libwmf-0.2.1, a.k.a. `The Inspector General's Nose'. I was, in fact, tempted to call it version 0.3.0, but I've been calling it 0.2.1 for so many preview snapshots that, well, to do otherwise now would seem like a betrayal. The most significant change is the introduction of redirectable character output streams (i.e., wmfStream) which should facilitate the writing of WMF importers. - Speaking of which, CVS sodipodi now has optional support for importing WMF, requiring libwmf-0.2.1, and an importer for AbiWord is in the works. This has, however, necessitated a slight change in the API, and people who use libwmf in conjuction with wv will need to upgrade to wv-0.7.0 or later. Other significant changes are support for a ghostscript-style fontmap and the beginnings of doxygen-generated documentation (which will grow more complete with future releases). Otherwise, there has been considerable clean-up, bug-fixes and improvement of both the source and the build system, and some additional functionality, including: (a) The .fig export uses scaling now, and has options to save images as PNG or JPEG. (b) The .svg export now supports inline (data URI) images and compression to .svgz (plus sodipodi-specific workarounds). (c) Use of metafile size info., if any (a mixed blessing). Special thanks to: (a) Matej Vila, for helping to make libwmf more Debian-friendly; (b) Michael Cree, for helping me to get libwmf working on Tru64; (c) Steve Oney, whose help I have not yet done justice to... Thanks also to: Bob Friesenhahn, Michal Jaegermann, Anil Madhavapeddy, Jacqueline Signore, Shuang Wang, Sean Young, and Kees Zeelenberg. Finally, having just assumed the mantle of maintainership, I would like to take this opportunity once again to thank Martin Vermeer for all of his work on libwmf. Francis James Franklin 22nd August, 2001 =============================================================================== Amendment #1 ------------ This version of libwmf is now officially part of the wvWare project, available by CVS under the module named `libwmf2'. I have added device layers for SVG (W3C's XML-based vector graphic format) and MVG (ImageMagick's proprietary vector graphic format); the X device layer has not been changed and I have no intention of changing it in the near future, but it works. I have also added a device layer for GNU plotutils, but currently it is only a shell, so don't use it. The MVG work is based on information supplied by Bob Friesenhahn who did the WMF coder for ImageMagick. (ImageMagick's WMF coder links against libwmf(1), not this version.) I am using version ImageMagick-5.3.3, and I don't know whether earlier (or later) versions will be compatible with the MVG format assumed by libwmf. In fact, I am already finding bugs, particularly with dashed lines... Also, I don't really know how to implement fonts; I suspect ImageMagick could do with some serious hacking on this point... Martin Vermeer has added a FIG device layer, so now there are two routes available if anyone wants to *edit* the images as vector graphics: (a) WMF->FIG for editing with xfig; (b) WMF->SVG for editing with, for example, sodipodi (best to get the *very* latest source for sodipodi; the GNOME-1.4 release and earlier are colour- blind). The svg & magick device layers write all bitmap data as PNG images, using filenames provided via the device layer interface. The current version of the GD library subsumed within libwmf is gd-2.0.0, with my additions. This supports 24-bit colour. There is some documentation, but the best way to learn how to use the various the device layers is to read the source in src/convert/ Francis James Franklin 13th May, 2001 =============================================================================== This is my own (i.e., unofficial) development version of libwmf which I propose as a candidate for release as (official) libwmf version 0.2.0. Although based on Caolan's excellent libwmf, there has been an almost complete restructuring to take libwmf away from it's batch-process origins and make it as well-behaved a library as possible. (1) The names have been changed to protect the innocent. All global / external variables have the prefix `wmf' (or, since the GD library is subsumed within libwmf, `gd'). With very few exceptions: (a) functions: wmf_function_name (...) (b) types: wmfType, or wmfType_t (c) macros: WMF_Macro (...) (2) It is my belief that device-layer (e.g., output) implementations should not need to know anything about wmf files or the interpreter's methods. In addition, the writing of such device-layers should be made as simple as possible, though not of course at the expense of image fidelity or quality. As such, I have crafted a new interface between the interpreter and the device layer, which I choose to call the `ipa' (as opposed to the `api' which is the `application / program interface'). There must also be an interface between the application and the device layer, but this third interface is independent of the interpreter. Although this may sound unnecessarily complicated, in fact it makes programming applications or device layers significantly easier. (3) With very few exceptions, all function calls refer to a variable of type `wmfAPI' which incorporates all data associated with a given wmf file. A final call to wmf_api_destroy frees up all memory allocated during the initialization and processing of the metafile. (4) (a) There is no longer any dependence on temporary files; all processing of the metafile is performed in-memory or w.r.t. original metafile. (b) Metafiles can be in-memory if desired; or applications can specify their own read/seek/tell functions for reading the metafile. (5) (a) Xpm dependence & system calls have been removed; libwmf provides bitmap scaling functionality. (b) Bitmaps are read using code taken from ImageMagick [?? - are there licensing issues to be addressed here?] (c) libwmf now uses freetype (2) for stringwidth calculations, and is bundled with the standard thirteen ghostscript fonts [?? - are there licensing issues to be addressed here?] (d) libwmf incorporates GD (gd-1.8.4 at time of writing) which supports freetype (2), with some enhancements (filled arcs & clipping). * * libz, libpng and freetype(2) are the sole required external libraries. * (6) (a) The build system uses automake and libtool, and the only library created is `libwmf', which includes the eps and gd device layers and the GD library as well as the interpreter and api. (b) Header files are installed in a `libwmf' sub-directory. (7) I have added the wmf examples with Tor Lillqvist's plug-in for the Gimp: http://www.iki.fi/tml/gimp/wmf [?? - are there licensing issues to be addressed here?] Currently the only device layers are eps [eps & ps] and gd [png & jpeg]. Implementing more should be relatively straight-forward. I recognize that, until device layers for X, xfig and magick exist, this proposed revision of libwmf is at a disadvantage... I have tested only with PPC Linux 2000 and (x86) Linux RH7. Francis James Franklin 4th March, 2001 ===============================================================================
