Features

     * Distiller
     * Works both for documents and for graphics
     * Single-page selection
     * Also converts from pdf back to PostScript and eps
     * Removal of preview headers from eps files
     * Cropping extra whitespace
     * Grayscaling (sometimes)
     * GUI- and command-line version
     * GUI-configurable preferences
     * Multiplatform: works unchanged on Windows, Unix/Linux and Mac OS X
     * Support for TeX Live

   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.

   Starting with the 2008 edition, epspdf is included in TeX Live as an
   optional package, complete with wrapper scripts epspdf and epspdftk which
   can be called from the command-line without further ado.

Prerequisites

   These are the required and optional prerequisites:

     * Ghostscript
     * pdftops from the xpdf suite, strongly recommended for better pdf to
       PostScript conversions
     * Ruby 1.8.x
     * Tcl/Tk is only required for the GUI interface. Only version 8.4 has
       been tested.
     * Optional: viewers for PostScript and pdf

   You may not have to install all of these yourself.

  Linux

   On a current Linux distribution you can almost certainly install
   everything from your distribution's package repositories. You may have to
   install Ruby's Tk bindings, in addition to Ruby and Tcl/Tk themselves. The
   name of such a package might be e.g. libtcltk-ruby. As to PostScript- and
   pdf viewers: epspdf tests for several popular viewers, but the
   configuration screen also lets you specify viewers manually.

  Mac OS X (Tiger and later)

   Ruby and Tcl/Tk are already part of the operating system. Ghostscript is
   included in MacTeX, but is also available via e.g. MacPorts. You can get
   pdftops from MacPorts as part of either Poppler or xpdf. Another source is
   [9]http://users.phg-online.de/tk/MOSXS/.

   If you want to compile xpdf it yourself, which is not hard, you can ignore
   warnings about X, Motif or FreeType not being found since these missing
   libraries won't affect the compilation of pdftops.

  Windows (Windows 2000 and later)

   If you use the TeXLive package (2008 or later):
           Epspdf and epspdftk will use Ghostscript and pdftops built into
           TeX Live. You still need to download and install Ruby and
           optionally Tcl/Tk.

   If you install from the setup program:
           This package includes a subset of Ruby/Tk, but you have to provide
           Ghostscript and pdftops yourself.

   If you use the zipfile:
           In this case, you have to provide everything yourself.

  URLs for the prerequisites

   Ghostscript and GSview ([10]http://pages.cs.wisc.edu/~ghost/)
           Contains sources and Windows binaries. The Windows binaries come
           with standard GUI Windows setup programs.

   XPDF ([11]http://www.foolabs.com/xpdf/)
           Sources and Windows binaries. The Windows binaries are packaged
           into a zipfile, which has to be manually unpacked. The Configure
           screen of epspdftk lets you browse for the chosen location. You
           have to do this only once.

   XPDF, Mac OS X binaries ([12]http://users.phg-online.de/tk/MOSXS/)
           These are universal binaries.

   TeX Live ([13]http://www.tug.org/texlive/)
           TeX Live 2008 includes epspdf as an optional install. For Windows,
           this version doesn't require external copies of pdftops or
           Ghostscript.

   MacTeX ([14]http://www.tug.org/mactex/)
           MacTeX is based on TeX Live. Its set of add-ons includes
           Ghostscript, and can be downloaded separately.

   The MacPorts Project ([15]http://www.macports.org/)
           MacTeX has Poppler- and xpdf packages either of which include
           pdftops.

   Ruby one-click installer fro Windows (
   [16]http://rubyforge.org/projects/rubyinstaller/)
           Current versions (1.8.4 and later) require Tcl/Tk to be separately
           installed.

   Old releases of Ruby one-click installer (
   [17]http://rubyforge.org/frs/?group_id=167)
           Versions prior to 1.8.4 include Tcl/Tk.

   Ruby source code ([18]http://www.ruby-lang.org/en/downloads/)
           For those people who prefer to roll their own...

   ActiveTcl from ActiveState (
   [19]http://activestate.com/Products/ActiveTcl/
           Get version 8.4, not 8.5.

Installation

   First make sure that the prerequisites are met. Then:

  TeX Live 2008

   Use TeX Live's package manager tlmgr for installation.

  Windows setup program

   Download the [20]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 [21]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 [22]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 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 [23]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. If
   you have TeX Live 2008 or later then you can assign <TeX Live
   root>\bin\win32\psv.bat as previewer for .ps- and .eps 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. You can also specify a previewer manually in the
   configuration screen; see the user guide, under [24]"The configuration
   screen"..

  Mac OS X

   Epspdftk will always use Preview as viewer under OS X.

Files

     * [25]epspdf.0.3.0.tgz preferred for Unix and Mac OS X
     * [26]epspdf.0.3.0.zip preferred for Windows
     * [27]epspdf.0.3.0.exe Windows setup program, including Ruby/Tk subset
     * [28]epspdf_app.0.2.01.zip Mac OS X applet for starting epspdftk.rb

  Older releases

     * [29]epspdf.0.2.12.tgz for Unix and Mac OS X
     * [30]epspdf.0.2.12.zip for Windows
     * [31]epspdf.0.2.12.exe Windows setup program
     * [32]epspdf.0.2.11.tgz for Unix and Mac OS X
     * [33]epspdf.0.2.11.zip for Windows

     * [36]epspdf.0.2.01.zip for Windows
     * [37]epspdf.0.2.exe, Windows setup program

Releases

   0.3.0
           Current version. Under Windows, now recognizes whether it is
           embedded in TeX Live 2008 and then uses ghostscript/pdftops from
           TeX Live. Also added TeX Live wrapper scripts. Uninstaller for
           Windows setup program. Bug fixes: now accepts non-numerical
           version strings for pdftops. No longer checks for viewers under
           Mac OS X.

   0.2.12
           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 packaged
           separately, under Mac OS X, and now has an intact resource fork.
           It has been removed from the other archives.
