Revision History
Revision $Revision: 2521 $ 2006-10-25 j.h

A filter is a special kind of tool designed to take an input layer or image, apply a mathematical algorithm to it, and return the input layer or image in a modified format. GIMP uses filters to achieve a variety of effects and those effects are discussed here.

The filters are divided into several categories:

1.1.  Preview

Most filters have a Preview where changes in the image are displayed, in real time (if the “Preview” option is checked), before being applied to the image.

Right clicking on the Preview window opens a submenu which lets you set the Style and the Size of checks representing transparency.
