GraphicsMagick Install README

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:

To use CVS over SSH:

        export CVS_RSH=ssh
        export CVSROOT=":ext:anoncvs@cvs.graphicsmagick.org:/GraphicsMagick"

or to use CVS with its built-in (and insecure) pserver protocol:

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

to set CVSROOT in the environment (adjust for 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

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.

- GraphicsMagick requires the BZLIB library from

            http://sources.redhat.com/bzip2/

              or

            ftp://sources.redhat.com/pub/bzip2/

          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 'dcraw' from

            http://www.cybercom.net/~dcoffin/dcraw/

          to read raw images from digital cameras.  Use similar to

            gm convert dcraw:infile outfile

        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. Note that
          enabling TT_CONFIG_OPTION_BYTECODE_INTERPRETER in FreeType's
          include/freetype/config/ftoption.h will produce better glyph
          renderings but may violate an Apple patent.

        o GraphicsMagick requires Ghostscript software (version 7.07 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 from

             http://gnuplot.sourceforge.net/

          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/

          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.graphicsmagick.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
          1.701.0 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.sane-project.org/

          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/libtiff/

          or via HTTP at

             http://www.remotesensing.org/libtiff/

          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. Since LZW
          was protected by Unisys patent until July 7, 2004, the TIFF library
          has not been including support for LZW compression. If you need to
          use LZW compression and libtiff is not yet updated to include it,
          support is available via a seperate LZW compression kit (a patch) at
          the sites listed above.

        o GraphicsMagick may optionally use the TRIO library from

             http://sourceforge.net/projects/ctrio/

          to substitute for the vsnprintf function when the operating system
          does not provide one. Older operating systems (e.g. Solaris 2.5)
          may not provide a vsnprintf function. If vsnprintf (or the TRIO
          replacement) is not used, then vsprintf is used instead, which
          decreases the security of GraphicsMagick due to possible buffer
          overrun exploits.

        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-1.2.0.9.tar.gz from the ftp directory.

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

          Please note that this library is not very portable. It is known to
          work properly under SPARC Solaris and Windows, but exhibits severe
          problems under FreeBSD and Linux.

        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/
