GraphicsMagick Image Processing System
======================================

.. meta::
   :description: GraphicsMagick is a robust collection of tools and libraries to read,
                 write, and manipulate an image in any of the more popular
                 image formats including GIF, JPEG, PNG, PDF, and Photo CD.
                 With GraphicsMagick you can create GIFs dynamically making it
                 suitable for Web applications.  You can also resize, rotate,
                 sharpen, color reduce, or add special effects to an image and
                 save your completed work in the same or differing image format.

GraphicsMagick is the swiss army knife of image processing. Comprised
of 282K physical lines (according to David A. Wheeler's `SLOCCount`_)
of source code in the base package (or 964K including 3rd party
libraries) it provides a robust and efficient collection of tools and
libraries which support reading, writing, and manipulating an image in
over 88 major formats including important formats like DPX, GIF, JPEG,
JPEG-2000, PNG, PDF, PNM, and TIFF.

Image processing is multi-threaded (`see the multi-thread benchmark
results`_) using OpenMP_ so that CPU-bound tasks scale linearly as
processor cores are added. OpenMP_ support requires compilation with
GCC 4.2 (or later), or use of any C compiler supporting at least the
OpenMP_ 2.0 specification.

GraphicsMagick is quite portable, and compiles under almost every general
purpose operating system that runs on 32-bit or 64-bit CPUs.
GraphicsMagick is available for virtually any Unix or Unix-like system,
including Linux. It also runs under `Windows <INSTALL-windows.html>`_
2000 and later (Windows 2000, XP, Vista, and 7), and MacOS-X.

GraphicsMagick supports huge images and has been tested with
gigapixel-size images. GraphicsMagick can create new images on the
fly, making it suitable for building dynamic Web
applications. GraphicsMagick may be used to resize, rotate, sharpen,
color reduce, or add special effects to an image and save the result
in the same or differing image format. Image processing operations are
available from the command line, as well as through C, C++, Lua, Perl,
PHP, Python, Tcl, Ruby, Windows .NET, or Windows COM programming
interfaces. With some modification, language extensions for
ImageMagick may be used.

GraphicsMagick is originally derived from ImageMagick_ 5.5.2 as of
November 2002 but has been completely independent of the ImageMagick
project since then. Since the fork from ImageMagick many improvements
have been made (see `NEWS`_) by many `authors`_ using an open
development model but without breaking the API or utilities operation.

Here are some reasons to prefer GraphicsMagick over ImageMagick:

  * GM is more efficient so it gets the job done faster using fewer
    resources.

  * GM is much smaller and tighter (3-5X smaller installation footprint).

  * GM is used to process billions of files at the world's largest photo
    sites (e.g. `Flickr`_ and `Etsy`_).
  
  * GM does not does not conflict with other installed software.

  * GM suffers from fewer security issues and exploits.

  * GM `valgrind`_'s 100% clean (memcheck and helgrind).
  
  * GM comes with a comprehensive `manual page`_.
  
  * GM provides API and ABI stability and managed releases that you can
    count on.
  
  * GM provides detailed yet comprehensible `ChangeLog`_ and `NEWS`_ files.
  
  * GM is available for free, and may be used to support both open and
    proprietary applications.
  
  * GM is distributed under an X11-style license (`MIT License`_),
    approved by the `Open Source Initiative`_, recommended for use by
    the `OSSCC`_, and compatible with the `GNU GPL`_.

  * GM source code is managed in Mercurial_, a distributed source
    control management tool which supports management of local
    changes.

  * GM developers contribute to other free projects for the public good.

GraphicsMagick is `copyrighted <Copyright.html>`_ by the GraphicsMagick
Group as well as many others.

Here are just a few examples of what GraphicsMagick can do:

  * Convert an image from one format to another (e.g. TIFF to JPEG)
  
  * Resize, rotate, sharpen, color reduce, or add special effects to an
    image
  
  * Create a montage of image thumbnails  
  
  * Create a transparent image suitable for use on the Web

  * Compare two images
  
  * Turn a group of images into a GIF animation sequence
  
  * Create a composite image by combining several separate images  
  
  * Draw shapes or text on an image  
  
  * Decorate an image with a border or frame  
  
  * Describe the format and characteristics of an image
