Gimp Software: Using the Quickmask Tool

A short form for the GNU image manipulation program, Gimp software is a raster graphics editor, and it is used in the retouching and editing of an image. It accomplishes essential image work-flow steps, such as editing, resizing, combining multiple images and also cropping of photos. Quickmask, on the other hand, is a convenient way to modify selections by using pixel changing tools such as erasers, a paintbrush and a plug-in filter.
