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.
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/
This program is covered by multiple licenses, which are described in Copyright.txt. You should have received a copy of Copyright.txt with this package; otherwise see http://www.graphicsmagick.org/www/Copyright.html.
