Revision 32219, 13.8 KB (checked in by ak19, 4 months ago)

Committing xpdf-tools binaries for mac (v. 4.00 as for Win and Linux xpdf-tools binaries committed before) as they work with the test files. Aiming to build our own xpdf-tools from src for unix sometime hereafter, but in the meantime, there are these binaries.

17What is Xpdf?
18-------------
19
20Xpdf is an open source viewer for Portable Document Format (PDF)
21files.  (These are also sometimes also called 'Acrobat' files, from
22the name of Adobe's PDF software.)  The Xpdf project also includes a
23PDF text extractor, PDF-to-PostScript converter, and various other
24utilities.
25
26The Xpdf viewer uses the Qt cross-platform GUI toolkit.  The other
27command line utilties do not require Qt.
28
29
30License & Distribution
31----------------------
32
33Xpdf is licensed under the GNU General Public License (GPL), version 2
34or 3.  This means that you can distribute derivatives of Xpdf under
35any of the following:
36  - GPL v2 only
37  - GPL v3 only
38  - GPL v2 or v3
39
40The Xpdf source package includes the text of both GPL versions:
41COPYING for GPL v2, COPYING3 for GPL v3.
42
43Please note that Xpdf is NOT licensed under "any later version" of the
44GPL, as I have no idea what those versions will look like.
45
46If you are redistributing unmodified copies of Xpdf (or any of the
47Xpdf tools) in binary form, you need to include all of the
48documentation: README, man pages (or help files), COPYING, and
49COPYING3.
50
51If you want to incorporate the Xpdf source code into another program
52(or create a modified version of Xpdf), and you are distributing that
53program, you have two options: release your program under the GPL (v2
54and/or v3), or purchase a commercial Xpdf source license.
55
56If you're interested in commercial licensing, please see the Glyph &
57Cog web site:

61
62Compatibility
63-------------
64
65Xpdf uses the Qt toolkit and runs on Linux, Windows, and OS X -- and
66probably other systems that have a Qt port.
67
68The non-GUI command line utilities (pdftops, pdftotext, pdftohtml,
69pdfinfo, pdffonts, pdfdetach, pdftoppm, pdftopng, and pdfimages) run
70on Linux, Windows, and OS X -- and should run on pretty much any
71system with a decent C++ compiler.
72
73If you compile Xpdf for a system not listed on the web page, please
74let me know.  If you're willing to make your binary available by ftp
75or on the web, I'll be happy to add a link from the Xpdf web page.  I
76have decided not to host any binaries I didn't compile myself (for
77disk space and support reasons).
78
79If you can't get Xpdf to compile on your system, send me email and
80I'll try to help.
81
82
83Getting Xpdf
84------------
85
86The latest version is available from:
87
88  http://www.xpdfreader.com/
89
90Source code and several precompiled executables are available.
91
92Announcements of new versions are posted to comp.text.pdf and emailed
93to a list of people.  If you'd like to receive email notification of
94new versions, just let me know.
95
96
97Running Xpdf
98------------
99
100To run xpdf, simply type:
101
102  xpdf file.pdf
103
104To generate a PostScript file, run pdftops:
105
106  pdftops file.pdf
107
108To generate a plain text file, run pdftotext:
109
110  pdftotext file.pdf
111
112There are several additional utilities (which are fully described in
113their man pages):
114
115  pdftohtml -- converts a PDF file to HTML
116  pdfinfo -- dumps a PDF file's Info dictionary (plus some other
117             useful information)
118  pdffonts -- lists the fonts used in a PDF file along with various
119              information for each font
120  pdfdetach -- lists or extracts embedded files (attachments) from a
121               PDF file
122  pdftoppm -- converts a PDF file to a series of PPM/PGM/PBM-format
123              bitmaps
124  pdftopng -- converts a PDF file to a series of PNG image files
125  pdfimages -- extracts the images from a PDF file
126
127Command line options and many other details are described in the man
128pages: xpdf(1), etc.
129
130All of these utilities read an optional configuration file: see the
131xpdfrc(5) man page.

143If you find a bug in Xpdf, i.e., if it prints an error message,
144crashes, or incorrectly displays a document, and you don't see that
145bug listed here, please send me email, with a pointer (URL, ftp site,
146etc.) to the PDF file.
