Xpdf ==== version 2.01 2002-dec-05 The Xpdf software and documentation are copyright 1996-2002 Glyph & Cog, LLC. Email: derekn@foolabs.com WWW: http://www.foolabs.com/xpdf/ The PDF data structures, operators, and specification are copyright 1***5-2001 Adobe Systems Inc. What is Xpdf? ------------- Xpdf is an open source viewer for Portable Document Format (PDF) files. (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, TrueType, or standard X 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 2.2 x86 system. In addition, it has been compiled by others on Solaris, AIX, HP-UX, SCO UnixWare, 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, 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 pdftopbm -- converts a PDF file to a series of 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 0.9x ------------------------ WARNING: Xpdf 1.x switched to a completely different config file setup than Xpdf 0.9x. Many of the configuration options that used to be X resources have been moved into the Xpdf config file. There are also lots of new and improved options. If you're upgrading from Xpdf 0.9x, please read through the sample config file (doc/sample-xpdfrc) and the xpdfrc(5) man page. The Asian language support has been pulled out into separate packages, loaded at run time. This is much cleaner than the 0.9x approach -- it makes the base distribution smaller, allows the language support packages to be upgraded separately, and lets users customize Xpdf for other text encodings without modifying the source. See the web site (http://www.foolabs.com/xpdf) for info on downloading the language support packages. All of the Xpdf tools, including the X viewer and the command line programs, read the same config file. They first attempt to read the user's personal config file: $HOME/.xpdfrc If it is not found, the Xpdf tools read a system-wide config file, typically something like: /usr/local/etc/xpdfrc (this location can be customized when building Xpdf). The Win32 command line tools look in the directory containing the executable, e.g.: C:/Program Files/Xpdf/xpdfrc Xpdf comes with a "sample-xpdfrc" file in the doc directory. This is a good starting point for constructing your own config file. For full details, please see the xpdfrc(5) man page. Fonts ----- By default, Xpdf will use X server fonts. It requires the following fonts: * Courier: medium-r, bold-r, medium-o, and bold-o * Helvetica: medium-r, bold-r, medium-o, and bold-o * Times: medium-r, bold-r, medium-i, and bold-i * Symbol: medium-r * Zapf Dingbats: medium-r Most X installations should already have all of these fonts (except maybe Zapf Dingbats). If Xpdf is built with support for t1lib (or FreeType 2), you can get much higher quality text by using Type 1 fonts instead of X server fonts. For example, you can use the Type 1 fonts that come with ghostscript. To do this, add the following lines to the xpdfrc file (e.g., /usr/local/etc/xpdfrc or $HOME/.xpdfrc): displayFontT1 Times-Roman /usr/local/share/ghostscript/fonts/n021003l.pfb displayFontT1 Times-Italic /usr/local/share/ghostscript/fonts/n021023l.pfb displayFontT1 Times-Bold /usr/local/share/ghostscript/fonts/n021004l.pfb displayFontT1 Times-BoldItalic /usr/local/share/ghostscript/fonts/n021024l.pfb displayFontT1 Helvetica /usr/local/share/ghostscript/fonts/n019003l.pfb displayFontT1 Helvetica-Oblique /usr/local/share/ghostscript/fonts/n019023l.pfb displayFontT1 Helvetica-Bold /usr/local/share/ghostscript/fonts/n019004l.pfb displayFontT1 Helvetica-BoldOblique /usr/local/share/ghostscript/fonts/n019024l.pfb displayFontT1 Courier /usr/local/share/ghostscript/fonts/n022003l.pfb displayFontT1 Courier-Oblique /usr/local/share/ghostscript/fonts/n022023l.pfb displayFontT1 Courier-Bold /usr/local/share/ghostscript/fonts/n022004l.pfb displayFontT1 Courier-BoldOblique /usr/local/share/ghostscript/fonts/n022024l.pfb displayFontT1 Symbol /usr/local/share/ghostscript/fonts/s050000l.pfb displayFontT1 ZapfDingbats /usr/local/share/ghostscript/fonts/d050000l.pfb You will need to replace '/usr/local/share/ghostscript/fonts' with the appropriate path on your system. 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.
