GIMP is image editing software, much like Photoshop. It is a multi-platform software application primarily used for image composition and editing. The basic tool may be augmented by plug-ins and extensions that allow the use of new file formats, effects filters and batch processing capabilities. GIMP was initially created to manipulate raster images, but has been extended to provide limited vector image and moving image support. A number of free extensions are available in the plugin registry.
