ImageMagick: Convert, Edit, and Compose Images

Introduction to ImageMagick

ImageMagick^®, version 6.2.5, is a free software suite to create, edit, and compose 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 Bézier 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 programs written in the programming languages C, Ch, C++, Java, Perl, PHP, Python, Ruby, Tcl/Tk, 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) including formats like GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX.
