ImageMagick is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bezier curves.
The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), JMagick (Java), L-Magick (Lisp), nMagick (Neko/haXe), MagickNet (.NET), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface, use ImageMagick to modify or create images dynamically and automagically.
ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may freely use, copy, modify, and distribute. Its license is compatible with the GPL. It runs on all major operating systems.
Here are just a few examples of what ImageMagick can do:
- * Format conversion: convert an image from one format to another (e.g. PNG to JPEG)
* Transform: resize, rotate, crop, flip or trim an image
* Transparency: render portions of an image invisible
* Draw: add shapes or text to an image
* Decorate: add a border or frame to an image
* Special effects: blur, sharpen, threshold, or tint an image
* Animation: create a GIF animation sequence from a group of images
* Text & comments: insert descriptive or artistic text in an image
* Image identification: describe the format and properties of an image
* Composite: overlap one image over another
* Montage: juxtapose image thumbnails on an image canvas
* Motion picture support: read and write the common image formats used in digital film work
* Image calculator: apply a mathematical expression to an image or image channels
* High dynamic-range images: accurately represent the wide range of intensity levels found in real scenes ranging from the brightest direct sunlight to the deepest darkest shadows.
* Large image support: read, process, or write mega- and giga-pixel image sizes
* Threads of execution support: ImageMagick is thread safe and many internal algorithms are already threaded to take advantage of speed-ups offered by the dual and quad-core processor technologies.

Significant changes since the last official ImageMagick release, include:
Code: Select all
2007-09-29 6.3.6-0 Anthony <anthony@griffith...> * Added Scaling 'derivitives' to -distort Arc, so image arcing is now sharp and clear as you approach the center of the distort. * Added " -set option:distort:viewport 'geometry' " special option that can be used to override the output image size and offset. * Fixed experimental use of -filter and -support in Resampling (more later). * Changed order for coordinate arguments in -distort (for leastsq addition) 2007-09-22 6.3.6-0 Cristy <quetzlzacatenango@image...> * Check the API version and quantum depth before loading a coder module or image filter (reference http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780). * Add exception to the image filter signature. * Get the execution path under Mac OS X. * TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c). * Fixed memory leak in CloneString() (reference http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763). * Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in CopyDelegateFile().
