The GIMP (GIMP is an acronym for GNU Image Manipulation Program) is a computer software application that started as an undergraduate project by Peter Mattis and Spencer Kimball at the University of California and has evolved into an application designed for retouching photographs, composing and authoring images. Its powerful capabilities as an image manipulation program make it a worthy competitor to other similar programs such as AdobePhotoshop or Corel PhotoPaint, but the biggest advantage of The GIMP is it's free availability although it's not freeware, rather it is an OSS (Open Source Software) program covered by the GPL license, which gives the user the freedom to access and also to change the source code that makes up the program. The Gimp offers a full suite of painting tools including brushes, a pencil, an airbrush, an ink tool, and cloning. Tile-based memory management so image size is limited only by available disk space; sub-pixel sampling for all paint tools, allowing for high-quality anti-aliasing; full Alpha channel
(transparency) support; layers and channels. Advanced scripting capabilities provided by a procedural database so you can call internal GIMP functions from external scripts, such as Script-Fu, Perl-Fu (Perl scripts) and Python-Fu (Python scripts). The GIMP offers multiple undo and redo, limited only by disk space; transformation tools including rotate, scale, shear, and flip. File formats supported include PostScript, JPEG, GIF, PNG, XPM, TIFF, TGA, MPEG, PCX, BMP and many others. Selection tools including rectangular, elliptical, free, fuzzy, paths, and intelligent scissors. The GIMP supports plug-ins that allow for the easy addition of new functions, new file formats, and new effects filters. The GIMP is probably best known for its use on the GNU/Linux platform, but there are many platforms that GIMP can run on, including GNU/Linux, Microsoft Windows 95, 98, NT4 and 2000, OpenBSD, NetBSD, FreeBSD, Solaris, SunOS, AIX, HP-UX, Tru64, Digital Unix, OSF/1, IRIX, OS/2 and BeOS.
