Gdtclft

GIMP

It is an extremely capable piece of software with many capabilities. It can be used as a simple paint program, a expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc.

GIMP is extremely expandedable and extensible. It is designed to be augmented with plugins 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.

ImageMagick

In addition to the image display program, ImageMagick also has command line programs that perform these functions:

• Convert an image from one format to another
• Resize, rotate, sharpen, color reduce, or add special effects to an image
• Create a framed thumbnail of an image
• Create a transparent image suitable for use on the Web
• Turn a group of images into a GIF animation sequence
• Create a composite image by combining several separate images
• Segment an image based on the color histogram
• Describe the format and characteristics of an image
• Retrieve, list, or print files from a remote network site

tkpaint

There is a large variety of operations that can be performed on a group of objects: scaling, rotation, relocation, reflection, and deformation with respect to inclination.

Tkpaint can be very useful for books or papers writers who are accustomed to draw their figures by themselves (don't assume that someone else will do it better than you!). It is easy to get an encapsulated PostScript output (EPS), and then to include it inside TeX or LaTeX files (via the epsf macro package).

Tkpaint is very easy to learn, and with little experience it is possible to to produce book quality slides in a short time. With more experience it is possible to produce unbelievably complex figures. Linux people who use xfig or xpaint may find Tkpaint more suitable for some of the things that they are trying to do.
