GIMP: Image and Photo Manipulation
The GNU Image Manipulation Program (the Gimp) is the open source image and photo manipulator alternative to Adobe's very popular and powerful Photoshop. The Gimp is indeed a very powerful tool for editing images and creating impressive graphics. It is one of the highlights of open source software, and demonstrates the quality that can be achieved through open source development.
A command line alternative, and one that provides a very powerful scripting capability, is Imagemagick.
This chapter provides a number of recipes for some common tasks using the GIMP. Many excellent books that unleash the full power of the GIMP are available and some are mentioned in Section 40.3.
