The GNU Image manipulation program, or GIMP to its friends, is an open source image-editing application for Unix and Linux operating systems. It is supplied with many Linux implementations and you can also download it from the Web.
Sven Neumann has been using the GIMP since 1997, and his GIMP Pocket Reference is a simple-structured guide to everything the GIMP has to offer, starting out with the tools and interface, moving through the menus and finishing with a table of supported file formats. It is a useful quick reference for those times when what should be obvious isn't, or as an introduction to the GIMP's feature set.
Occasionally, Neumann goes beyond mere functional description and provides more detailed explanation of techniques like selection, layers and channels. There is also a short overview of colour models, and drawing and layer models.
The GIMP Pocket Reference won't tell you how to set up a scanner or graphics tablet to work with GIMP, or how to go about scripting, retouching or compositing. If you are looking for information on configuration, scripting and practical hands-on advice then you need one of the more comprehensive manuals, such as GIMP User's Manual. But if you can't remember how to select the ink tool brush, or add an alpha channel this handy little reference provides a direct and low-cost route to the answer. --Ken McMahon
