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 `_ 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 via the Mercurial distributed source control management

tool (http://mercurial.selenic.com/). GraphicsMagick may be retrieved

via the following command:

  hg clone http://graphicsmagick.hg.sourceforge.net/hgweb/graphicsmagick/graphicsmagick/ GM

Mercurial provides a complete stand-alone repository which contains

the full history of the GraphicsMagick project.  You may use the

cloned repository for your own purposes related to GraphicsMagick

(e.g. manage local GraphicsMagick changes), and can easily pull

GraphicsMagick updates from the main repository whenever you like.

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 `_.

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 / Linux / \*BSD / MacOS-X / Cygwin / MinGW:

    `Installation on Unix-like systems `_

  * Microsoft Windows (Via "setup" style installer or from source code):

    `Installation on Microsoft Windows `_

Add-On Libraries & Programs

---------------------------

To further enhance the capabilities of GraphicsMagick, you may want to

get these programs or libraries. Note that these packages are already

integrated into the GraphicsMagick Mercurial repository for use when

building under Microsoft Windows:

* 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 and Ghostscript Fonts (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 and Ghostscript Fonts (see

  below) are 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.

* GraphicsMagick requires Ghostscript software (version 9.04

  recommended) available from

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

      or

    http://sourceforge.net/projects/ghostscript/

  to read the Postscript or the Portable Document Format (PDF).

  Ghostscript Fonts are available from

    https://sourceforge.net/projects/gs-fonts/

  Ghostscript is available for use under both free (GPL) and

  commercial licenses.  We are not lawyers so we can not provide

  advice as to when the commercial license from Artifex is required.

  Please make sure that you are aware of Ghostscript licencing and

  usage terms if you plan to use it in some sort of commercial

  situation.

  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.

  If the Ghostscript library is used, then please be aware that

  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 (1.11 or later, including

  2.X) 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 and write the JBIG image format.

* GraphicsMagick requires the WebP library version 0.1.99 (or later)

  available via HTTPS from

     https://developers.google.com/speed/webp/

  to read and write the WebP image format.

* GraphicsMagick requires the Independent JPEG Group's software

  available from

     http://www.ijg.org/

  to read and write 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().

* On Unix-type systems, Windows/MinGW, and Windows/Cygwin,

  GraphicsMagick requires libltdl from libtool in order to support

  building GraphicsMagick with dynamically loadable modules.  Libtool

  is available via anonymous FTP from

     ftp://ftp.gnu.org/pub/gnu/libtool/

* 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 programming errors.

* GraphicsMagick requires libwmflite from 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.  If the other features of libwmf are

  not needed, then the '--disable-heavy' option may be used to only

  build libwmflite.

  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 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 libxml2 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 liblzma library from XZ Utils available from

     http://www.tukaani.org/xz/

  to support TIFF with LZMA compression and future LZMA-compression

  features (yet to be developed).  The utilities from this package are

  also necessary in order to decompress GraphicsMagick packages

  distributed with ".xz" or ".lzma" extensions.

* GraphicsMagick requires the ZLIB library from

     http://www.zlib.net/

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