Installing GraphicsMagick
=========================
.. contents::
:local:
Executive Summary
-----------------
GraphicsMagick provides a comprehensive collection of utilities,
programming interfaces, and GUIs, to support file format conversion,
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 <Copyright.html>`_ for the GraphicsMagick licence.
Availability
------------
The master ftp site for GraphicsMagick distributions is
ftp://ftp.graphicsmagick.org/pub/GraphicsMagick/. Bandwidth on this
site is very limited, so it is recommended to download from SourceForge
at http://sourceforge.net/projects/graphicsmagick/files/ if
possible.
GraphicsMagick is a continual work in progress. The very latest code is
available from CVS. GraphicsMagick 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 which
includes the core GraphicsMagick sources along with all necessary
third-party libraries 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 gm(1) manual
page. Also read the GraphicsMagick frequently asked questions in the
file `www/FAQ.html <FAQ.html>`_.
Installation
------------
GraphicsMagick may be compiled from source code for virtually any
modern Unix system (including Linux and MacOS X) and Microsoft Windows.
Installation instructions may be found in the following files (or their
HTML equivalents):
* Unix / MacOS-X / Cygwin / MinGW:
`INSTALL-unix.txt <INSTALL-unix.html>`_
* Microsoft Windows (Via "setup" style installer or from source code):
`INSTALL-windows.txt <INSTALL-windows.html>`_
Add-On Libraries & Programs
---------------------------
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://www.bzip.org/
to read and write BZip compressed MIFF images.
* 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).
* GraphicsMagick requires 'dcraw' from
http://www.cybercom.net/~dcoffin/dcraw/
to read raw images from digital cameras. Dcraw is invoked
automatically when used to read files using a common RAW file format
extension.
* GraphicsMagick requires 'fig2dev' provided in the transfig package
from
http://www.xfig.org/
to read the Fig image format. Ghostscript (see below) is also
required.
* 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.
* GraphicsMagick requires Ghostscript software (version 8.50 recommended)
available from
http://pages.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) under Linux. If this library is installed, GraphicsMagick may
be configured to use it. We do **NOT** recommend using this library
under Unix type systems. The Ghostscript library does not support
concurrency since only one instance of the interpreter is available.
Unix systems will obtain better performance from executing Ghostscript as
an external process since then multiple interpreters may execute at
once on multiple CPU cores.
Ghostscript provides its own modified version of libjpeg and libJasper
while GraphicsMagick will be using these libraries as provided with the
system. If Ghostscript is not using the same libraries, then
identically named symbols may be used from the wrong code, causing
confusion or a program crash. 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 lose
compatibility with some Postscript files).
* 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. Ghostscript (see above) is also required.
* GraphicsMagick requires the LCMS library available from
http://www.littlecms.com/
to perform ICC CMS color management.
* GraphicsMagick requires gnuplot available from
http://gnuplot.sourceforge.net/
to read GNUPLOT plot files (with extension gplt). Ghostscript (see
above) is also required.
* GraphicsMagick requires Graphviz available from
http://www.graphviz.org/
to read Graphvis 'dot' digraph files (with extension dot).
Ghostscript (see above) is also required.
* GraphicsMagick requires html2ps available from
http://user.it.uu.se/~jan/html2ps.html
to rasterize HTML files. Ghostscript (see above) is also required.
* GraphicsMagick requires the JBIG-Kit software available via
HTTP from
http://www.cl.cam.ac.uk/~mgk25/jbigkit/
to read the JBIG image format.
* GraphicsMagick requires the Independent JPEG Group's software
available from
http://www.ijg.org/
to read the JPEG v1 image format.
Apply this JPEG patch to Independent JPEG Group's (6b release!)
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.
* GraphicsMagick requires the JasPer Project's JasPer library version
1.701.0 (or later) available via http from
http://www.ece.uvic.ca/~mdadams/jasper/
to read and write the JPEG-2000 format. Please note that JasPer 1.900.1
may have a problem when used with GraphicsMagick's modules build. To
solve this problem, edit the file src/libjasper/base/jas_init.c and
comment out the line which invokes atexit().
* GraphicsMagick requires the MPEG utilities from the MPEG Software
Simulation Group, which are available via anonymous FTP as
ftp://ftp.GraphicsMagick.org/pub/GraphicsMagick/delegates/mpeg2vidcodec_v12.tar.gz
to read or write the MPEG image format.
* GraphicsMagick requires the LIBPNG library, version 1.0 or above, from
http://www.libpng.org/pub/png/pngcode.html
to read or write the PNG, MNG, or JNG image formats. LIBPNG depends
upon the ZLIB library (see below).
* 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.
* GraphicsMagick requires rawtorle from the Utah Raster Toolkit
available via anonymous FTP as
ftp://ftp.graphicsmagick.org/pub/GraphicsMagick/delegates/urt-3.1b.tar.Z
to write the RLE image format.
* GraphicsMagick requires scanimage from
http://www.sane-project.org/
to import an image from a scanner device.
* 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. Libtiff 3.8.2 or later is recommended.
* 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.
* GraphicsMagick may optionally use the umem memory allocation library
which is included in Sun's Solaris operating system or available from
https://labs.omniti.com/trac/portableumem
to provide enhanced versions of the standard memory allocation
facilities. Use of umem may improve performance for multi-threaded
programs and provides access to debugging features that detect memory
leaks, buffer overruns, multiple frees, use of uninitialized data, use
of freed data, and many other common pro- gramming errors.
* 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.
* 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-1.2.0.10.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.
* 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. For MacOS-X, X11 is a
system install time option.
A free X server for Microsoft Windows is included as part of
Cygwin and may be selected from the Cygwin installer. Cygwin is
available from
http://www.cygwin.com/
There is a nearly free X server available for Windows and Macintosh at
http://www.microimages.com/downloads/mix/
* 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.
* GraphicsMagick requires the ZLIB library from
http://www.zlib.net/
to read or write the PNG or Zip compressed MIFF images.
