> GraphicsMagick Utilities

GraphicsMagick provides a powerful command line utility which may be used to access all GraphicsMagick functions. Gm uses a consistent set of options (see options documentation). GraphicsMagick provides access to major command modes via a single executable command-line program called 'gm'; for example, to use the "convert" mode, type "gm convert ...". The available command modes and links to their documentation are shown in the following table:

GM Command Mode

Description

gm animate

animate a sequence of images

gm composite

composite images together

gm conjure

gm convert

convert an image or sequence of images

gm display

gm identify

gm import

gm mogrify

gm montage

The gm utility makes it easy to perform complex image processing operations using a single command. It may be invoked from scripts, or from other programs in order to automate the processing of thousands of images.
