Introduction to GIMP

GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such

tasks as photo retouching, image composition and image authoring.

It has many capabilities. GIMP can be used as a simple paint program, an expert quality photo

retouching program, an on-line batch processing system, a mass production image renderer, an image

format converter, and etc.

GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to

do just about anything. The advanced scripting interface allows everything from the simplest task to

the most complex image manipulation procedures to be easily scripted.

GIMP is written and developed under X11 on UNIX platforms. But basically the same code also runs

on MS Windows and Mac OS X.
