ImageMagickTM, version 6.2.0, is a free software suite for the cre
ation, modification and display of bitmap images. It can read, convert
and write images in a large variety of formats. Images can be cropped,
colors can be changed, various effects can be applied, images can be
rotated and combined, and text, lines, polygons, ellipses and Bzier
curves can be added to images and stretched and rotated.
ImageMagick is free software: it is delivered with full source code and
can be freely used, copied, modified and distributed. Its license is
compatible with the GPL. It runs on all major operating systems.
Most of the functionality of ImageMagick can be used interactively from
the command line; more often, however, the features are used from pro
grams written in the programming languages Perl, C, C++, Python, PHP,
Ruby, Tcl/Tk or Java, for which ready-made ImageMagick interfaces
(PerlMagick, Magick++, PythonMagick, MagickWand for PHP, RMagick,
TclMagick, and JMagick) are available. This makes it possible to modify
or create images automatically and dynamically.
ImageMagick supports many image formats (over 90 major formats) includ
ing popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF.
ImageMagick includes a number of command-line utilities for manipulat
ing images. Most of you are probably accustom to editing images one at
a time with a graphical user interface (GUI) with such programs as gimp
or Photoshop. However, a GUI is not always convenient. Suppose you want
to process an image dynamically from a web script or you want to apply
the same operations to many images or repeat a specific operation at
different times to the same or different image. For these types of
operations, the command-line image processing utility is appropriate.
In the paragraphs below, find a short description for each command-line
tool.Click on the program name to get details on the program usage and
a list of command-line options that alters how the program performs. If
you are just getting acquianted with ImageMagick, start at the top of
the list, the convert program, and work your way dowm. Also be sure to

to convert, compose, or edit images from the command-line.
