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 + + Appendix: 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. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) 19yy <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 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., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, 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) 19yy 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. + + <signature of Ty Coon>, 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. diff --git a/kpdf/Makefile.am b/kpdf/Makefile.am new file mode 100644 index 00000000..fd5ccb49 --- /dev/null +++ b/kpdf/Makefile.am @@ -0,0 +1,30 @@ +SUBDIRS = xpdf conf core ui shell + +INCLUDES = -I$(srcdir)/xpdf -I$(srcdir)/xpdf/goo -I$(top_builddir)/kpdf $(all_includes) $(FREETYPE_CFLAGS) + +METASOURCES = AUTO + +messages: rc.cpp + $(EXTRACTRC) `find . -name "*.rc" -o -name "*.ui"` >> rc.cpp + $(XGETTEXT) `find . -name "*.cpp" -o -name "*.cc" -o -name "*.h"` -o $(podir)/kpdf.pot + +KDE_ICON = kpdf + +######################################################################### +# KPART SECTION +######################################################################### +kde_module_LTLIBRARIES = libkpdfpart.la + +libkpdfpart_la_SOURCES = dcop.skel error.cpp part.cpp +libkpdfpart_la_LDFLAGS = -module $(KDE_PLUGIN) $(all_libraries) +libkpdfpart_la_LIBADD = xpdf/xpdf/libxpdf.la conf/libkpdfconf.la \ + core/libkpdfcore.la ui/libkpdfui.la $(LIB_KPARTS) \ + $(LIB_KFILE) $(LIB_KDEPRINT) $(LIB_KUTILS) -lm + +partdesktopdir = $(kde_servicesdir) +partdesktop_DATA = kpdf_part.desktop + +partrcdir = $(kde_datadir)/kpdfpart +partrc_DATA = part.rc + +part.lo: conf/settings.h diff --git a/kpdf/README.internals.png b/kpdf/README.internals.png Binary files differnew file mode 100644 index 00000000..92153173 --- /dev/null +++ b/kpdf/README.internals.png diff --git a/kpdf/TODO b/kpdf/TODO new file mode 100644 index 00000000..6a00e14a --- /dev/null +++ b/kpdf/TODO @@ -0,0 +1,173 @@ +TODO - KPdf MAIN HEAD +Legend: + ADD - ADDed (new feature) + CHG - CHanGed (existing behavior) + FIX - FIXed (bug or regression) + MRG - MeRGed (code from a branch or a patch) + +In progress: + -- 2005-Feb-26: Merge from 'kpdf_annotations' branch -- + +More items (first items will enter 'In progress list' first): +-> pageview: add scrollbar marks for bookmarks (like kate) +-> screen editing (annotations): framework (BR67300,BR62793) +-> screen editing (annotations): tools (BR67300), yellow notes 'post-it' like +-> go to next/previous bookmark actions (showing in thumbnailslist rmb popup too) +-> viewport restoring: sometimes it seems to restore the viewport a bit under where it was +-> viewport restoring: save the page width setting between runs (save/restore zoom factor) +-> presentation: provide a pageX/totalPages indicator in addition to the circle one +-> cleanup code and update README.png +-> search: use shortcut for 'find next' action (not the default one) in find-ahead +-> show Viewport in ThumbnailsList (blended/contour) +-> Delay TOC (DocumentSynapsis) generation (and move it on thread) +-> add a way to handle "named xpdf links" in KPDFLink instead of resolving all destinations + when displaying a page (speedups a lot generation of page with many links) +-> refactor ThumbnailsList to do internal rendering as pageview does (way faster + than using QScrollView + inserted Widgets and saves 8% on document loading) +-> usability: layout 2PPV [1 2,3 4,5 6] -> [1,2 3,4 5]. add option for 'ebook' style alignment +-> usability: trigger redraw on 'filter text' on current page (need new highligh engine first) +-> abstract TextPage generation (the last xpdf dependant class!). then go dancing in the + streets. +-> Dom framework to cache document metadata.

(These are also sometimes also called 'Acrobat' files, from +the name of Adobe's PDF software.) The Xpdf project also includes a +PDF text extractor, PDF-to-PostScript converter, and various other +utilities. + +Xpdf runs under the X Window System on UNIX, VMS, and OS/2. The non-X +components (pdftops, pdftotext, etc.) also run on Win32 systems and +should run on pretty much any system with a decent C++ compiler. + +Xpdf is designed to be small and efficient. It can use Type 1 or +TrueType fonts. + + +Distribution +------------ + +Xpdf is licensed under the GNU General Public License (GPL), version +2. In my opinion, the GPL is a convoluted, confusing, ambiguous mess. +But it's also pervasive, and I'm sick of arguing. And even if it is +confusing, the basic idea is good. + +In order to cut down on the confusion a little bit, here are some +informal clarifications: + +- I don't mind if you redistribute Xpdf in source and/or binary form, + as long as you include all of the documentation: README, man pages + (or help files), and COPYING. (Note that the README file contains a + pointer to a web page with the source code.) + +- Selling a CD-ROM that contains Xpdf is fine with me, as long as it + includes the documentation. I wouldn't mind receiving a sample + copy, but it's not necessary. + +- If you make useful changes to Xpdf, please make the source code + available -- post it on a web site, email it to me, whatever. + +If you're interested in commercial licensing, please see the Glyph & +Cog web site: + + http://www.glyphandcog.com/ + + +Compatibility +------------- + +Xpdf is developed and tested on a Linux 2.4 x86 system. + +In addition, it has been compiled by others on Solaris, AIX, HP-UX, +Digital Unix, Irix, and numerous other Unix implementations, as well +as VMS and OS/2. It should work on pretty much any system which runs +X11 and has Unix-like libraries. You'll need ANSI C++ and C compilers +to compile it. + +The non-X components of Xpdf (pdftops, pdftotext, pdfinfo, pdffonts, +pdftoppm, and pdfimages) can also be compiled on Win32 systems. See +the Xpdf web page for details. + +If you compile Xpdf for a system not listed on the web page, please +let me know. If you're willing to make your binary available by ftp +or on the web, I'll be happy to add a link from the Xpdf web page. I +have decided not to host any binaries I didn't compile myself (for +disk space and support reasons). + +If you can't get Xpdf to compile on your system, send me email and +I'll try to help. + +Xpdf has been ported to the Acorn, Amiga, BeOS, and EPOC. See the +Xpdf web page for links. + + +Getting Xpdf +------------ + +The latest version is available from: + + http://www.foolabs.com/xpdf/ + +or: + + ftp://ftp.foolabs.com/pub/xpdf/ + +Source code and several precompiled executables are available. + +Announcements of new versions are posted to several newsgroups +(comp.text.pdf, comp.os.linux.announce, and others) and emailed to a +list of people. If you'd like to receive email notification of new +versions, just let me know. + + +Running Xpdf +------------ + +To run xpdf, simply type: + + xpdf file.pdf + +To generate a PostScript file, hit the "print" button in xpdf, or run +pdftops: + + pdftops file.pdf + +To generate a plain text file, run pdftotext: + + pdftotext file.pdf + +There are four additional utilities (which are fully described in +their man pages): + + pdfinfo -- dumps a PDF file's Info dictionary (plus some other + useful information) + pdffonts -- lists the fonts used in a PDF file along with various + information for each font + pdftoppm -- converts a PDF file to a series of PPM/PGM/PBM-format + bitmaps + pdfimages -- extracts the images from a PDF file + +Command line options and many other details are described in the man +pages (xpdf.1, etc.) and the VMS help files (xpdf.hlp, etc.). + + +Upgrading from Xpdf 2.xx +------------------------ + +WARNING: Xpdf 3.00 switched to a new PDF rasterizer, which no longer +uses X fonts. You'll need a set of Base-14 fonts -- the URW fonts +distributed with ghostscript can be used for this. Xpdf will search +for the URW fonts, but if you have them installed in a non-standard +directory, you'll need to set up an xpdfrc config file to point to +them. For full details, please see the xpdfrc(5) man page. + + +Compiling Xpdf +-------------- + +See the separate file, INSTALL. + + +Bugs +---- + +If you find a bug in Xpdf, i.e., if it prints an error message, +crashes, or incorrectly displays a document, and you don't see that +bug listed here, please send me email, with a pointer (URL, ftp site, +etc.) to the PDF file. + + +Acknowledgments +--------------- + +Thanks to: + +* Patrick Voigt for help with the remote server code. +* Patrick Moreau, Martin P.J.
