   Epspdf has been created with TeX in mind. For TeX and its derivatives, 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 converting text back to PostScript. 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, which will be checked
   for when epspdf starts:

     * 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)

   Warning! Epspdf has not yet been tested with Snow Leopard. There is a
   report that epspdftk fails under Snow Leopard.

   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)

   By itself, Windows lacks any of the prerequisites of epspdf. However, a
   TeX installation may fill some of the gaps, and there is a special Windows
   installer which includes a partial Ruby installation. See the table below:

     TeX distribution          Installer                   Zipfile           
   (1) MikTeX and TeX Live 2008 include a hidden Ghostscript which is always 
   installed, and which epspdf knows how to find. Caveat: although older     
   versions of TeX Live include a Ghostscript installer, it is not impossible
   to install an older TeX Live without Ghostscript, in which case you have  
   to provide a Ghostscript yourself.                                        
   (2) With TeX Live ≥ 2008, you are better off installing the TeX Live      
   package, which also gives you wrapper batchfiles epspdf.bat and           
   epspdftk.bat. You still need to install Ruby and Tcl/Tk.                  
     TeX Live[10](1)    No additional            Ruby, Tcl/Tk[11](2)         
                        requirements                                         
          MiKTeX        Pdftops (optional)       Pdftops (optional); Ruby,   
                                                 Tcl/Tk(optional)            
                        Ghostscript, pdftops     Ghostscript;                
        Other/None      (optional)               pdftops(optional), Ruby,    
                                                 Tcl/Tk (optional)           

  URLs for the prerequisites

   Ghostscript and GSview ([12]http://pages.cs.wisc.edu/~ghost/)
           Contains sources and Windows binaries. The Windows binaries come
           with standard GUI Windows setup programs.

   XPDF ([13]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 ([14]http://users.phg-online.de/tk/MOSXS/)
           These are universal binaries.

   TeX Live ([15]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 but does not include Ruby or Tcl/Tk.

   MacTeX ([16]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 ([17]http://www.macports.org/)
           MacTeX has Poppler- and xpdf packages either of which include
           pdftops.

   Ruby one-click installer for Windows (
   [18]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 (
   [19]http://rubyforge.org/frs/?group_id=167)
           Versions prior to 1.8.4 include Tcl/Tk.

   Ruby source code ([20]http://www.ruby-lang.org/en/downloads/)
           For those people who prefer to roll their own...

   ActiveTcl from ActiveState (
   [21]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 [22]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 [23]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>" %*

   With such a batchfile, the caller has to take care of quoting:

 epspdf "my file.eps" "my file.pdf"

   Epspdf[tk] has been tested with Windows 2000, Windows XP and Windows
   Vista.

  Unix/Linux

   Download the [24]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

   You can install as for Unix/Linux. Here, too, all files should be in the
   same directory.

   There is also a compressed disk image epspdf.x.x.x.dmg.gz which wraps
   epspdftk into a Max OS X "app". Double-click once to expand, a second time
   to mount, then drag epspdftk.app to the Applications folder.

   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 programs 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. For Windows
   only, there is an additional "View with..." button to select a viewer
   yourself.

  Unix/Linux

   Supported PostScript viewers include evince, gv, gsview and okular. These
   are also listed as pdf viewers. Additional pdf viewers are xpdf, gpdf,
   epdfview and acroread/Adobe Reader. You can also specify a previewer
   manually in the configuration screen; see the [25]user manual..

  Mac OS X

   Epspdftk will always use the default pdf viewer under OS X, usually
   Preview or Adobe Reader.

     * [26]epspdf.0.4.2.tgz preferred for Unix and Mac OS X
     * [27]epspdf.0.4.2.zip preferred for Windows

Releases

   0.4.2
           Current version. More liberal documentation license. Slight
           documentation updates.

   0.4.1
           Documentation: added section on bitmaps. Windows setup program:
           added missing Tcl/Tk licenses. Mac: double-clickable epspdftk.app
           with included epspdftk replaces double-clickable epspdf.app
           add-on.

   0.4.0
           Optionally uses hires boundingbox. Faster startup due to simpler
           testing of prerequisites. Grayscaling: support for HSB color
           model, although I yet have to encounter a PostScript file using
           this. Manual converted to texinfo format. Windows: new "View
           with..." button; support for MikTeX's built-in Ghostscript;
           streamlined Ruby subset, with Tcl/Tk compiled from source.

   0.3.0
           Under Windows, now recognizes whether it is embedded in TeX Live
           2008 and then can use 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.

   0.2
