+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111 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
+
+ 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

+
+ 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) 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.

+
+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.

+ Epspdf and epspdftk
+
+ A multiplatform GUI- and command-line converter for [e]ps and pdf.

+
+ Epspdf has been created with TeX users in mind. For them, eps and pdf are
+ the preferred graphics formats.
+
+ Ghostscript can convert PostScript to pdf. However, few people are
+ prepared to deal with the ghostscript command-line. Several command-line
+ utilities try to help out, e.g. epstopdf, a2ping, and the convert utility
+ from ImageMagick. But for most users this is still not good enough.
+
+ Epspdftk adds a GUI, with buttons to select options and with dialogs for
+ opening and saving files.
+
+ A lot more can be done if you can round-trip between PostScript and pdf.
+ Although Ghostscript can go from pdf to PostScript, pdftops does a much
+ better job. This opens several new possibilities: grayscaling and
+ computing a better boundingbox for either eps- or pdf graphics, and page
+ selection from multipage PostScript- and pdf documents. Epspdf will use
+ pdftops if it can find it, and silently does whatever back-and-forth
+ conversions are necessary.
+
+ The command-line program epspdf is written in Ruby. Epspdftk, its GUI
+ companion, in Ruby/Tk.
+
+Prerequisites
+
+ Windows with setup progrogam
+
+ Download Ghostscript and GSview from the [11]Ghostscript site. Ghostscript
+ and GSview each come with a standard Windows setup program.
+
+ You can get pdftops as part of the xpdf suite from the [12]xpdf site.
+ Download the zipfile with Windows binaries and unpack it in a location of
+ your choice. The Configure screen of epspdftk lets you browse for this
+ location. You only have to do this once. Xpdf itself is not in this zip
+ file.
+
+ The necessary Ruby components are already included in the setup program.
+
+ Windows zipfile with separately installed Ruby
+
+ For Ghostscript, GSview and the xpdf suite, see above.
+
+ You can get a [13]one-click Ruby installer from [14]Rubyforge. For Ruby
+ version 1.8.4 and later you have to download and install Tcl/Tk
+ separately, in the form of [15]ActiveTcl. If you are only interested in
+ the command-line version then you can leave out ActiveTcl.
+
+ Unix/Linux
+
+ You need Ghostscript, preferably xpdf/pdftops, Ruby (version at least 1.8)
+ and for GUI use also Ruby/Tk. These will almost certainly be available as
+ packages from your distribution.
+
+ Mac OS X
+
+ Ghostscript and xpdf are available via the [16]Fink Project, in the Text
+ section.
+
+ If you don't (want to) use Fink, you can download and install Gerben
+ Wierda's i-Installer from the [17]i-Installer Home Page and then use the
+ i-Installer to download and install the Ghostscript i-package.
+
+ There is a [18]package for the xpdf suite at
+ [19]http://users.phg-online.de/tk/MOSXS/. Or you can compile it yourself.
+ You can download the source from the [20]xpdf site. For compilation, you
+ need to have XCode installed, but nothing else, I think, at least not
+ under Tiger. You can safely omit the xpdf- and pdftoppm components if
+ configure says that they will not be compiled because of missing
+ libraries.
+
+ Ruby 1.8.2 and Ruby/Tk are part of Mac OS X Tiger. X11 needs to be
+ installed, although Ruby/Tk is not an X11 application. For earlier
+ versions of Mac OS X, you are on your own.
+
+Installation
+
+ Windows with setup program
+
+ Download the [21]epspdftk setup program. You can run it in the usual way,
+ by double-clicking. The setup program will create entries in your start
+ menu for epspdftk and for the user manual.
+
+ Windows zipfile
+
+ Download the [22]epspdf zip file, unpack it somewhere and create a
+ shortcut for epspdftk.rbw. If you plan to use the command-line version,
+ put a batchfile in a directory on your path with the line
+
+ "<path_to_ruby.exe>" "<path_to_epspdf.rb>" %1 %2 %3 %4 %5 %6 %7 %8 %9
+
+ Epspdf[tk] has been tested with Windows 2000 and Windows XP.
+
+ Unix/Linux
+
+ Download the [23]tar.gz archive and unpack it in some directory. All files
+ should be in the same directory; that is how they find each other. If you
+ plan to use epspdf.rb from the command-line, then you may want to create a
+ shell script epspdf such as
+
+ #!/bin/sh
+ <path_to_epspdf>/epspdf.rb $*
+
+ and put it somewhere on your path.
+
+ You can do the same for epspdftk. The first command-line parameter will be
+ interpreted as startup directory for the file browser.
+
+ Mac OS X
+
+ Install as for Unix/Linux. Here, too, all files should be in the same
+ directory.
+
+ You can try to start epspdftk.rb from the dock or by doubleclicking. If
+ that doesn't work out, give the [24]epspdf.app applet a try. After
+ unpacking, move the file epspdf.app to the same directory as the .rb
+ files. The zipfile also includes this file in text format
+ (epspdf.applescript).
+
+ Epspdf mostly duplicates functionality of Preview. But having an alternate
+ conversion engine means that you can have another shot at problem files.
+
+Preview programs
+
+ Windows
+
+ Epspdftk will use the default Windows viewers for PostScript and pdf.
+ Without GSview, you probably won't be able to view PostScript files.
+
+ Unix/Linux
+
+ Supported PostScript viewers include evince, gv, ggv and kghostview. These
+ are also listed as pdf viewers. Additional pdf viewers are xpdf, gpdf and
+ acroread/Adobe Reader. If you think that I omitted a PostScript- or pdf
+ viewer, let me know and I'll probably add it in the next release.
+
+ Mac OS X
+
+ Epspdftk will always use Preview as viewer under OS X.

+Releases
+
+ 0.2.12
+ Current version. Bug fixes: log rotation now works. Under Windows,
+ sometimes boundingboxes couldn't be calculated. This was caused by
+ double quotes within backquotes. This is now avoided by using
+ short filenames within backquotes. Minor changes in user guide.
+
+ 0.2.11
+ Minor fixes. Changes in documentation.
+
+ 0.2.10
+ A computed boundingbox is now expanded by one point in all
+ directions. This should prevent too-tight cropping. There is no
+ interface for changing this amount; it can only be changed by
+ hand-editing the bb_spread option in the .epspdfrc file or in the
+ HKCU\software\epspdf registry key.
+ The File Open dialog remembers the last directory visited (between
+ calls, not between program sessions).
+ Changes in documentation.
+
+ 0.2.01
+ Fixes to the Applescript applet epspdf.app for starting up
+ epspdftk under Mac OS X. It picks up the terminal search path and
+ no longer requires correct settings in
+ $HOME/.MacOSX/environment.plist.
+ Epspdf.app is now [41]packaged separately, under Mac OS X, and now
+ has an intact resource fork. It has been removed from the other
+ archives.

+
+<h2>Overview</h2>
+
+<p>Epspdftk converts files between eps, pdf and general
+PostScript. The main screen lets you open a file, select some options
+and convert the file.</p>
+
+<p>When opening a file, epspdf tries to find out file type and, in
+the case of a pdf file, the number of pages. This information is
+displayed in the box in the upper half of the screen.</p>
+
+<p class="display"><img src="images/main_w32.png" alt=""/></p>
+
+<h2>Viewing</h2>
+
+<p>The View button at the bottom of the screen calls an appropriate
+external viewer. For Windows this is determined by the default Open
+command, for OS X it is always Preview, and under Linux it is
+configurable; see below under <a href="#configure">The Configuration
+screen.</a></p>
+
+<p>The View button is grayed if epspdf thinks that there is no
+previewer for the current file.</p>

+<p><a name="gray"><i>Grayscaling:</i></a> Simple color figures can
+be converted to grayscale. Grayscaling will fail for bitmapped data
+and for advanced color models. 'Try harder to grayscale' will handle
+a few more cases, but may take longer and still won't handle
+bitmaps.</p>
+
+<p><i>Call for assistance:</i> If a PostScript color expert is
+reading this: please have a look at makegray.pro and see whether you
+can come up with something that handles more color models.</p>
+
+<p><i>Compute tight boundingbox:</i> This option is only available
+if a single page is converted.</p>
+
+<p><i>Page selection:</i> The only possibilities are selecting a
+single page or selecting all pages. When converting to eps you are
+restricted to a single page.</p>
+
+<p>For general PostScript files, there is no quick way to determine
+the number of pages, so the program won't check beforehand whether
+you picked an existing page. If you picked a non-existent page, the
+program will abort. If you don't like that, convert the entire
+document to pdf first - which will be done behind the scenes
+anyhow.</p>
+
+<p>Specifying options such as grayscaling or page selection may
+require several roundtrips between PostScript or eps and pdf. If
+epspdf cannot use pdftops then some combinations of options will not
+be available.</p>
+
+<h2>Converting</h2>
+
+<p>The Convert and save... button calls up a file save dialog, with
+appropriate default extension. After a successful conversion, the
+result becomes the new current file, so you can judge the result by
+pressing the View button again.</p>
+
+<p class="display"><img src="images/dia_save.png" alt=""/></p>
+
+<h2><a name="configure">The configuration screen</a></h2>
+
+<p>Epspdftk also has a configuration screen. The settings here are
+preserved between sessions. Pay particular attention to 'Intended
+use' under PDF CONVERSION. Choose 'prepress' for pdfs which are
+intended for commercial printing. This option will try to embed all
+fonts, among other things. More and more often, printshops insist on
+this. With luck, Ghostscript fonts and system fonts will be used for
+fonts which were not originally embedded.</p>
+
+<p>Under Windows, this screen also lets you tell the program where
+to find pdftops.exe. Under Linux, it lets you pick PostScript- and
+pdf previewers.</p>
+
+<p class="display"><img src="images/config_mac.png" alt=""/></p>
+
+<h2>Adding standard fonts to an existing pdf</h2>
+
+<p>You can add standard fonts such as Times and Helvetica to an
+existing pdf: first, convert to ps, with 'Convert all pages'
+selected. Then, make sure that in the configuration screen 'Intended
+use' is set to prepress, then convert back to pdf.</p>
+
+<p>If this option is set to screen, then standard fonts will be
+removed instead of added. This option may also affect the resolution
+of bitmaps.</p>
+
+<h2>Eps preview headers</h2>
+
+<p>Preview headers are quietly stripped from eps files. These
+preview headers are used by e.g. desktop-publishing software to
+represent eps files on screen without having to interpret the
+PostScript code itself. Epspdf currently has no option to preserve
+or add them.</p>
+
+<h2>Exporting PostScript from Windows programs</h2>
+
+<p>Often, the only way to get EPS or PostScript from a Windows
+program is by 'printing' to a PostScript file. From some programs,
+you can print a selection. A suitable driver which comes with
+Windows is Generic / MS Publisher Imagesetter. Pay attention to the
+printer properties: avoid the 'Optimize for speed' setting and choose
+Outline for font downloading. These options can be found under the
+Advanced button.</p>
+
+<p>Other possibilities are the TpX and wmf2eps programs, which both
+have options to write clipboard contents to an emf file. Wmf2eps
+uses a printer driver in the background. For faithful conversion,
+pick wmf2eps; for subsequent editing, choose TpX. Both programs are
+availbable from <a href="http://www.tug.org/ctan.html">CTAN</a>.</p>
+
+<h2>Command-line use</h2>
+
+<p>Epspdf.rb, the library for epspdftk.rb, does double duty as
+command-line version of epspdftk.rb. Type <tt>epspdf.rb -h</tt> for
+help. It shares configuration settings with epspdftk.</p>
+
+<h2>Troubleshooting</h2>
+
+<h3>Grayscaling fails</h3>
+
+<p>See above, under <a href="#gray">Grayscaling.</a> Epspdf is
+limited by what can be done by the backend tools, i.e. Ghostscript
+and pdftops.</p>
+
+<h3>Part of the graphic gets cut off</h3>
+
+<p>I have seen this happen with eps files generated by printing
+landscape PowerPoint slides to PostScript with the Encapsulated
+PostScript output option. Using the Archive output option instead
+solved the problem. In general, experiment a bit in generating
+your PostScript.</p>
+
+<h3>Resources for troubleshooting</h3>
+
+<p><i>Logfile.</i> Epspdf and epspdftk maintain a log file
+epspdf.log in your home directory or, in case of Windows, your
+profile directory. This profile directory may be c:\Documents and
+Settings\&lt;your user name>. Otherwise, open a DOS box and type
+'<tt>echo %USERPROFILE%</tt>', which will produce this
+information.</p>
+
+<p>This logfile lists all Ghostscript- and pdftops program
+calls plus error information. 'EPCallError' is probably a program
+error. 'EPSystemError' is more likely caused by a faulty file, but
+may be a program error as well.</p>
+
+<p><i>Temporary files.</i> The temporary files may give clues as
+well. They will be deleted at the end of the session (for the
+command-line version, give a -d parameter to keep the temporary
+files). Check the logfile which temporary files have been
+created.</p>

+
+<p>Epspdf has been created with TeX users in mind. For them, eps and
+pdf are the preferred graphics formats.</p>
+
+<p>Ghostscript can convert PostScript to pdf. However, few people
+are prepared to deal with the ghostscript command-line. Several
+command-line utilities try to help out, e.g. epstopdf, a2ping, and
+the convert utility from ImageMagick. But for most users this is
+still not good enough.</p>
+
+<p>Epspdftk adds a GUI, with buttons to select options and with
+dialogs for opening and saving files.</p>
+
+<p>A lot more can be done if you can round-trip between PostScript
+and pdf. Although Ghostscript can go from pdf to PostScript, pdftops
+does a much better job. This opens several new possibilities:
+grayscaling and computing a better boundingbox for either eps- or pdf
+graphics, and page selection from multipage PostScript- and pdf
+documents. Epspdf will use pdftops if it can find it, and silently
+does whatever back-and-forth conversions are necessary.</p>
+
+<p>The command-line program epspdf is written in Ruby. Epspdftk,
+its GUI companion, in Ruby/Tk.</p>
+
+<h2><a name="prerequisites"/>Prerequisites</h2>
+
+<h3>Windows with setup progrogam</h3>
+
+<p>Download Ghostscript and GSview from the <a
+href="http://www.cs.wisc.edu/~ghost/">Ghostscript site.</a>
+Ghostscript and GSview each come with a standard Windows setup
+program.</p>
+
+<p>You can get pdftops as part of the xpdf suite from the <a
+href="http://www.foolabs.com/xpdf/">xpdf site.</a> Download the
+zipfile with Windows binaries and unpack it in a location of your
+choice. The Configure screen of epspdftk lets you browse for this
+location. You only have to do this once. Xpdf itself is not in this
+zip file.</p>
+
+<p>The necessary Ruby components are already included in the setup
+program.</p>
+
+<h3>Windows zipfile with separately installed Ruby</h3>
+
+<p>For Ghostscript, GSview and the xpdf suite, see above.</p>
+
+<p>You can get a <a
+href="http://rubyforge.org/projects/rubyinstaller/">one-click Ruby
+installer</a> from <a href="http://rubyforge.org/">Rubyforge.</a>
+For Ruby version 1.8.4 and later you have to download and install
+Tcl/Tk separately, in the form of <a
+href="http://activestate.com/Products/ActiveTcl/">ActiveTcl.</a> If
+you are only interested in the command-line version then you can
+leave out ActiveTcl.</p>
+
+<h3>Unix/Linux</h3>
+
+<p>You need Ghostscript, preferably xpdf/pdftops, Ruby (version at
+least 1.8) and for GUI use also Ruby/Tk. These will almost certainly
+be available as packages from your distribution.</p>
+
+<h3>Mac OS X</h3>
+
+<p>Ghostscript and xpdf are available via the <a
+href="http://fink.sourceforge.net/">Fink Project</a>, in the Text
+section.</p>
+
+<p>If you don't (want to) use Fink, you can download and
+install Gerben Wierda's i-Installer from the <a
+href="http://ii2.sourceforge.net/">i-Installer Home Page</a> and
+then use the i-Installer to download and install the Ghostscript
+i-package.</p>
+
+<p>There is
+a <a
+href="http://users.phg-online.de/tk/MOSXS/xpdf-tools-3.dmg">package</a>
+for the xpdf suite
+at <a
+href="http://users.phg-online.de/tk/MOSXS/">http://users.phg-online.de/tk/MOSXS/.</a>
+Or you can compile it yourself. You can download the source from
+the <a href="http://www.foolabs.com/xpdf/">xpdf site</a>. For
+compilation, you need to have XCode installed, but nothing else, I
+think, at least not under Tiger. You can safely omit the xpdf- and
+pdftoppm components if configure says that they will not be compiled
+because of missing libraries.</p>
+
+<p>Ruby 1.8.2 and Ruby/Tk are part of Mac OS X Tiger. X11 needs to
+be installed, although Ruby/Tk is <i>not</i> an X11 application. For
+earlier versions of Mac OS X, you are on your own.</p>
+
+<h2><a name="install"/>Installation</h2>
+
+<h3>Windows with setup program</h3>
+
+<p>Download the <a href="epspdf.0.2.12.exe">epspdftk setup
+program.</a> You can run it in the usual way, by double-clicking. The
+setup program will create entries in your start menu for epspdftk
+and for the user manual.</p>
+
+<h3>Windows zipfile</h3>
+
+<p>Download the <a href="epspdf.0.2.12.zip">epspdf zip file</a>,
+unpack it somewhere and create a shortcut for epspdftk.rbw. If you
+plan to use the command-line version, put a batchfile in a directory
+on your path with the line</p>
+
+<pre>
+"&lt;path_to_ruby.exe>" "&lt;path_to_epspdf.rb>" %1 %2 %3 %4 %5 %6 %7 %8 %9
+</pre>
+
+<p>Epspdf[tk] has been tested with Windows 2000 and Windows XP.</p>
+
+<h3>Unix/Linux</h3>
+
+<p>Download the <a href="epspdf.0.2.12.tgz">tar.gz archive</a> and
+unpack it in some directory. All files should be in the same
+directory; that is how they find each other. If you plan to use
+epspdf.rb from the command-line, then you may want to create a shell
+script <tt>epspdf</tt> such as</p>
+
+<pre>
+#!/bin/sh
+&lt;path_to_epspdf>/epspdf.rb $*
+</pre>
+
+<p>and put it somewhere on your path.</p>
+
+<p>You can do the same for epspdftk. The first command-line
+parameter will be interpreted as startup directory for the file
+browser.</p>
+
+<h3>Mac OS X</h3>
+
+<p>Install as for Unix/Linux. Here, too, all files should be in the
+same directory.</p>
+
+<p>You can try to start epspdftk.rb from the dock or by
+doubleclicking. If that doesn't work out, give the <a
+href="epspdf_app.0.2.01.zip">epspdf.app</a> applet a try. After
+unpacking, move the file <tt>epspdf.app</tt> to the same directory
+as the .rb files. The zipfile also includes this file in text format
+(<tt>epspdf.applescript</tt>).</p>
+
+<p>Epspdf mostly duplicates functionality of Preview. But having an
+alternate conversion engine means that you can have another shot at
+problem files.</p>
+
+<h2><a name="preview"/>Preview programs</h2>
+
+<h3>Windows</h3>
+
+<p>Epspdftk will use the default Windows viewers for PostScript and
+pdf. Without GSview, you probably won't be able to view PostScript
+files.</p>
+
+<h3>Unix/Linux</h3>
+
+<p>Supported PostScript viewers include evince, gv, ggv and
+kghostview. These are also listed as pdf viewers. Additional pdf
+viewers are xpdf, gpdf and acroread/Adobe Reader. If you think that
+I omitted a PostScript- or pdf viewer, let me know and I'll probably
+add it in the next release.</p>
+
+<h3>Mac OS X</h3>
+
+<p>Epspdftk will always use Preview as viewer under OS X.</p>

+ Epspdf and epspdftk User Guide
+
+ A multiplatform GUI- and command-line converter for [e]ps and pdf.
+
+ Siep Kroonenberg,
+ siepo at cybercomm dot nl
+
+Overview
+
+ Epspdftk converts files between eps, pdf and general PostScript. The main
+ screen lets you open a file, select some options and convert the file.
+
+ When opening a file, epspdf tries to find out file type and, in the case
+ of a pdf file, the number of pages. This information is displayed in the
+ box in the upper half of the screen.
+
+Viewing
+
+ The View button at the bottom of the screen calls an appropriate external
+ viewer. For Windows this is determined by the default Open command, for OS
+ X it is always Preview, and under Linux it is configurable; see below
+ under [1]The Configuration screen.
+
+ The View button is grayed if epspdf thinks that there is no previewer for
+ the current file.
+
+Conversion options
+
+ Grayscaling: Simple color figures can be converted to grayscale.
+ Grayscaling will fail for bitmapped data and for advanced color models.
+ 'Try harder to grayscale' will handle a few more cases, but may take
+ longer and still won't handle bitmaps.
+
+ Call for assistance: If a PostScript color expert is reading this: please
+ have a look at makegray.pro and see whether you can come up with something
+ that handles more color models.
+
+ Compute tight boundingbox: This option is only available if a single page
+ is converted.
+
+ Page selection: The only possibilities are selecting a single page or
+ selecting all pages. When converting to eps you are restricted to a single
+ page.
+
+ For general PostScript files, there is no quick way to determine the
+ number of pages, so the program won't check beforehand whether you picked
+ an existing page. If you picked a non-existent page, the program will
+ abort. If you don't like that, convert the entire document to pdf first -
+ which will be done behind the scenes anyhow.
+
+ Specifying options such as grayscaling or page selection may require
+ several roundtrips between PostScript or eps and pdf. If epspdf cannot use
+ pdftops then some combinations of options will not be available.
+
+Converting
+
+ The Convert and save... button calls up a file save dialog, with
+ appropriate default extension. After a successful conversion, the result
+ becomes the new current file, so you can judge the result by pressing the
+ View button again.
+
+The configuration screen
+
+ Epspdftk also has a configuration screen. The settings here are preserved
+ between sessions. Pay particular attention to 'Intended use' under PDF
+ CONVERSION. Choose 'prepress' for pdfs which are intended for commercial
+ printing. This option will try to embed all fonts, among other things.
+ More and more often, printshops insist on this. With luck, Ghostscript
+ fonts and system fonts will be used for fonts which were not originally
+ embedded.
+
+ Under Windows, this screen also lets you tell the program where to find
+ pdftops.exe. Under Linux, it lets you pick PostScript- and pdf previewers.
+
+Adding standard fonts to an existing pdf
+
+ You can add standard fonts such as Times and Helvetica to an existing pdf:
+ first, convert to ps, with 'Convert all pages' selected. Then, make sure
+ that in the configuration screen 'Intended use' is set to prepress, then
+ convert back to pdf.
+
+ If this option is set to screen, then standard fonts will be removed
+ instead of added. This option may also affect the resolution of bitmaps.
+
+Eps preview headers
+
+ Preview headers are quietly stripped from eps files. These preview headers
+ are used by e.g. desktop-publishing software to represent eps files on
+ screen without having to interpret the PostScript code itself. Epspdf
+ currently has no option to preserve or add them.
+
+Exporting PostScript from Windows programs
+
+ Often, the only way to get EPS or PostScript from a Windows program is by
+ 'printing' to a PostScript file. From some programs, you can print a
+ selection. A suitable driver which comes with Windows is Generic / MS
+ Publisher Imagesetter. Pay attention to the printer properties: avoid the
+ 'Optimize for speed' setting and choose Outline for font downloading.
+ These options can be found under the Advanced button.
+
+ Other possibilities are the TpX and wmf2eps programs, which both have
+ options to write clipboard contents to an emf file. Wmf2eps uses a printer
+ driver in the background. For faithful conversion, pick wmf2eps; for
+ subsequent editing, choose TpX. Both programs are availbable from [2]CTAN.
+
+Command-line use
+
+ Epspdf.rb, the library for epspdftk.rb, does double duty as command-line
+ version of epspdftk.rb. Type epspdf.rb -h for help. It shares
+ configuration settings with epspdftk.
+
+Troubleshooting
+
+ Grayscaling fails
+
+ See above, under [3]Grayscaling. Epspdf is limited by what can be done by
+ the backend tools, i.e. Ghostscript and pdftops.
+
+ Part of the graphic gets cut off
+
+ I have seen this happen with eps files generated by printing landscape
+ PowerPoint slides to PostScript with the Encapsulated PostScript output
+ option. Using the Archive output option instead solved the problem. In
+ general, experiment a bit in generating your PostScript.
+
+ Resources for troubleshooting
+
+ Logfile. Epspdf and epspdftk maintain a log file epspdf.log in your home
+ directory or, in case of Windows, your profile directory. This profile
+ directory may be c:\Documents and Settings\<your user name>. Otherwise,
+ open a DOS box and type 'echo %USERPROFILE%', which will produce this
+ information.
+
+ This logfile lists all Ghostscript- and pdftops program calls plus error
+ information. 'EPCallError' is probably a program error. 'EPSystemError' is
+ more likely caused by a faulty file, but may be a program error as well.
+
+ Temporary files. The temporary files may give clues as well. They will be
+ deleted at the end of the session (for the command-line version, give a -d
+ parameter to keep the temporary files). Check the logfile which temporary
+ files have been created.

+
+# Operations on a PostScript- or pdf file.
+# The focus is on converting between eps and pdf.
+
+# Code is organized as a set of single-step conversion methods plus an
+# any-to-any conversion.
+
+# `Target' is not a parameter; all conversions write to a new temp
+# file. Conversions can be chained: object.conversion1( params
+# ).conversion2( params ) ... The final temp file is moved or copied to
+# the desired destination by the main program (which can be epspdf
+# itself).
+
+# The use of exception handling makes it unnecessary to inspect return
+# values.
+
+# Limitation
+# HiRes boundingboxes are ignored.
+# Two reasons:
+# - they get lost anyhow on conversion to pdf
+# - They are not required so when you find one you have to make sure
+# that it doesn't refer to an included eps. This would
+# require additional logic.
