Welcome to GraphicsMagick.

GraphicsMagick provides a comprehensive collection of utilities,
programming interfaces, and GUIs, to support image processing and 2D vector
rendering.

GraphicsMagick is originally based on ImageMagick from ImageMagick Studio
(which was originally written by John Cristy at Dupont). The goal of
GraphicsMagick is to provide the highest quality product possible while
encouraging open and active participation from all interested developers.
The GraphicsMagick usage license is designed to allow it to be used for any
application, including proprietary or GPLed applications. Please see the
file Copyright.txt for the GraphicsMagick licence.

AVAILABILITY

  GraphicsMagick is currently under development.  It may be retrieved
  via CVS using the following procedure:

  Use

    export CVSROOT=":pserver:anonymous@cvs.graphicsmagick.org:/GraphicsMagick"

  or

    setenv CVSROOT=":pserver:anonymous@cvs.graphicsmagick.org:/GraphicsMagick"

  to set CVSROOT in the environment (depending on your shell), or prepend
  -d followed by the CVS root to every command. For example


    cvs -d ":pserver:anonymous@cvs ...

  For brevity the following examples assume that CVSROOT is set in the
  environment.

    cvs login
    [ enter "anonymous" ]

    cvs co GraphicsMagick

  If you would like to retrieve the (huge) Windows source package use

    cvs co GraphicsMagick-NT

  If  you  would like to retrieve *everything* associated with
  GraphicsMagick (useful or not) use

    cvs co GraphicsMagick-World

DOCUMENTATION

  Open the file index.html in a web browser, or refer to the manual pages
  for the display(1), animate(1), montage(1), import(1), mogrify(1),
  identify(1), composite(1), and convert(1) commands. The GraphicsMagick(1)
  manual page provides details for command options and will also aid with
  understanding library interfaces. Also read the GraphicsMagick frequently
  asked questions in the file www/Magick.html.

MAGICK DELEGATES

  To further enhance the capabilities of GraphicsMagick, you may want to
  get these programs or libraries. Note that the Windows source package
  (equivalent to CVS module "GraphicsMagick-NT") includes (and builds) all
  of the library-based packages listed here.

    o GraphicsMagick requires the BZLIB library from

        http://sourceware.cygnus.com/bzip2/index.html

      to read and write BZip compressed MIFF images.

    o GraphicsMagick requires ralcgm from

        http://www.agocg.ac.uk/train/cgm/ralcgm.htm

      to read the Computer Graphics Metafile (CGM) image format. You also
      need Ghostscript (see below).

    o GraphicsMagick requires fig2dev from

        ftp://ftp.x.org/contrib/applications/drawing_tools/transfig

      to read the Fig image format.

    o GraphicsMagick requires the FreeType software, version 2.0 or above,
      available as

        http://www.freetype.org/

      to annotate with TrueType and Postscript Type 1 fonts.

    o GraphicsMagick requires Ghostscript software (version 7.05 recommended)
      available from

        http://www.cs.wisc.edu/~ghost/

      to read the Postscript or the Portable Document format. Ghostscript
      is used to annotate an image when the FreeType library is not used,
      or an X server is not available. See the FreeType library above for
      another means to annotate an image. Note, Ghostscript must support
      the ppmraw device (type gs -h to verify). If Ghostscript is
      unavailable, the Display Postscript X11 extension is used to
      rasterize a Postscript document (assuming you define HasDPS and DPS
      is available). The DPS extension is less robust than Ghostscript in
      that it will only rasterize one page of a multi-page document.

      Ghostscript (release 7.0 and later) may optionally install a library
      (libgs). If this library is installed, GraphicsMagick may be
      configured to use it. Note that Ghostscript provides its own modified
      version of libjpeg and that symbols from this libjpeg may be confused
      with symbols with the stand-alone libjpeg. If conflicts cause JPEG to
      fail (JPEG returns an error regarding expected structure sizes), it
      may be necessary to use Ghostscript's copy of libjpeg for
      GraphicsMagick, and all delegate libraries which depend on libjpeg,
      or convince Ghostscript to build against an unmodified installed JPEG
      library (and loose compatibility with some Postscript files).

    o GraphicsMagick requires hp2xx available from

         http://www.gnu.org/software/hp2xx/hp2xx.html

      to read the HP-GL image format. Note that HPGL is a plotter file
      format. HP printers usually accept PCL format rather than HPGL format.

    o GraphicsMagick requires the LCMS library available from

         http://www.littlecms.com/

      to perform ICC CMS color management.

    o GraphicsMagick requires gnuplot available via anonymous FTP as

         ftp://ftp.dartmouth.edu/pub/gnuplot/gnuplot-3.7.tar.gz

      to read GNUPLOT plot files (with extension gplt).

    o GraphicsMagick requires html2ps available from

         http://www.tdb.uu.se/~jan/html2ps.html

      to rasterize HTML files.

    o GraphicsMagick requires the JBIG-Kit software available via
      HTTP from

         http://www.cl.cam.ac.uk/~mgk25/jbigkit/

      or via anonymous FTP as

         ftp://ftp.informatik.uni-erlangen.de/pub/doc/ISO/JBIG/

      to read the JBIG image format.

    o GraphicsMagick requires the Independent JPEG Group's software
      available via anonymous FTP as

         ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v6b.tar.gz

      to read the JPEG v1 image format.

      Apply this JPEG patch to Independent JPEG Group's source distribution
      if you want to read lossless jpeg-encoded DICOM (medical) images:

         ftp://ftp.imagemagick.org/pub/GraphicsMagick/delegates/ljpeg-6b.tar.gz

      Use of lossless JPEG is not encouraged. Unless you have a requirement
      to read lossless jpeg-encoded DICOM images, please disregard the patch.

    o GraphicsMagick requires the JasPer Project's Jasper library version
      1.700.2 available via http from

         http://www.ece.uvic.ca/~mdadams/jasper/

      to read and write the JPEG-2000 format.

    o GraphicsMagick requires the MPEG utilities from the MPEG Software
      Simulation Group, which are available via anonymous FTP as

         ftp://ftp.mpeg.org/pub/mpeg/mssg/mpeg2vidcodec_v12.tar.gz

      to read or write the MPEG image format.

    o GraphicsMagick requires the PNG library, version 1.0 or above, from

         http://www.libpng.org/pub/png/pngcode.html

      to read the PNG image format.

    o GraphicsMagick requires ra_ppm from Greg Ward's Radiance software
      available from

         http://radsite.lbl.gov/radiance/HOME.html

      to read the Radiance image format.

    o GraphicsMagick requires rawtorle from the Utah Raster Toolkit
      available via anonymous FTP as

         ftp://ftp.cs.utah.edu/pub/dept/OLD/pub/urt-3.1b.tar.Z

      to write the RLE image format.

    o GraphicsMagick requires scanimage from

         http://www.mostang.com/sane/
								 
      to import an image from a scanner device.

    o GraphicsMagick requires Sam Leffler's TIFF software available via
      anonymous FTP at

         ftp://ftp.remotesensing.org/pub/libtiff/

      or via HTTP at

         http://www.libtiff.org/

      to read the TIFF image format. It in turn optionally requires the
      JPEG and ZLIB libraries. Support for JPEG, ZIP, and LZW compression
      must be explicitly enabled by editing libtiff Makefiles. The TIFF
      library no longer includes support for LZW compression due to patent
      issues. If you need to use LZW compression, support is available via
      a seperate LZW compression kit (a patch) at the sites listed above.

    o GraphicsMagick requires libwmf 0.2.5 (or later) from

         http://sourceforge.net/projects/wvware/

      to render files in the Windows Meta File (WMF) metafile format
      (16-bit WMF files only, not 32-bit "EMF"). This is the format
      commonly used for Windows clipart (available on CD at your local
      computer or technical book store). WMF support requires the FreeType
      2 library in order to render TrueType and Postscript fonts.

      While GraphicsMagick uses the libwmflite (parser) component of the
      libwmf package which does not depend on any special libraries, the
      libwmf package as a whole depends on FreeType 2 and either the
      xmlsoft libxml, or expat libraries. Since GraphicsMagick already uses
      libxml (for reading SVG and to retrieve files via HTTP or FTP), it is
      recommended that the options '--without-expat --with-xml' be supplied
      to libwmf's configure script.

      GraphicsMagick's WMF renderer provides some of the finest WMF
      rendering available due its use of antialiased drawing algorithms.
      You may select a background color or texture image to render on. For
      example, "-background '#ffffffff'" renders on a transparent
      background while "-texture plasma:fractal" renders on a fractal image.

       A free set of Microsoft Windows fonts may be retrieved from
       "http://sourceforge.net/projects/corefonts/". Note that the license
       for these fonts requires that they be distributed in the original
       .exe form, but the Linux folks have found ways to deal with that on
       non-Windows systems.

    o GraphicsMagick requires the FlashPIX library version 1.2.0 from the
      Digital Imaging Group in order to support the FlashPIX format. The
      FlashPIX library may be obtained from GraphicsMagick anonymous CVS by
      checking out the 'fpx' module, or retrieving the file
      libfpx-1.2.0.5.tar.gz from the ftp directory.

         ftp://ftp.imagemagick.org/pub/GraphicsMagick/delegates/.

    o GraphicsMagick requires an X server for the 'display', 'animate', and
      'import' functions to work properly. Unix systems usually provide an X
      server as part of their standard installation.

      A free X server for Microsoft Windows is available from

         http://sources.redhat.com/win32-x11/

      The Cygwin port of XFree86 may also be used. It is available from

         http://www.cygwin.com/xfree/

      There is a nearly free X server available for Windows and Macintosh at

         http://www.microimages.com/freestuf/mix/

    o GraphicsMagick requires libxml available from

         http://xmlsoft.org/

      to read the SVG image format and to retrieve files from over a
      network via FTP and HTTP.

    o GraphicsMagick requires the ZLIB library from

         http://www.gzip.org/zlib/

      to read or write the PNG or Zip compressed MIFF images.

    o GraphicsMagick requires a background texture for the TILE format and
      for the -texture option of montage(1). You can use your own or get
      samples from

         http://the-tech.mit.edu/KPT/
