7.3The GIMP

GNU Image Manipulation Programme (GIMP) is the default graphic application in Ubuntu, licensed under the GNU General Public License. It is an open-source multi-platform image manipulation tool, available in many languages. You can use GIMP to re-touch photos, compose and create images, re-size, crop, manipulate colours and convert image formats.

GIMP has a number of useful features:

•A full suite of painting tools, including brushes, a pencil and an airbrush

•Selection tools such as rectangle, ellipse, free, fuzzy and bezier

•Transformation tools such as rotate, scale, shear and flip

•Tile-based memory management so that the image size is limited only by available disk space

•Multiple undo/re-do operations limited only by disk space

•Advanced scripting capabilities

•Layers and channels for complex drawings

•Sub-pixel sampling for all paint tools to minimise distortion while representing high-resolution images in lower resolution or stretched mode

•Full alpha channel support to simulate transparency in images

•Support for multiple file formats, including GIF, JPEG, PNG, XPM, TIFF, TGA, MPEG, PS, PDF, PCX and BMP
