Raster graphics editor

From Wikipedia, the free encyclopedia

A raster graphics editor is a computer program that allows users to paint and edit pictures interactively on the computer screen and save them in one of many popular “bitmap” or “raster” formats such as JPEG, PNG, GIF and TIFF.

Usually an image viewer is preferred over a raster graphics editor for viewing images.

Some editors specialize in the editing of photo-realistic images such as the popular Adobe Photoshop, while others are more geared to artist-created illustrations, like the Adobe Fireworks.
