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 commands via a single executable command-line program called gm; for example, to use the "convert" command, type gm convert .... The available commands and links to their documentation are shown in the following table:

Command Description
animate Animate a sequence of images
composite Composite images together
conjure Cxecute a Magick Scripting Language (MSL) XML script
compare Compare two images using statistics and/or visual differencing
convert Convert an image or sequence of images
display Display an image on a workstation running X
identify Describe an image or image sequence
import Capture an application or X server screen
mogrify Transform an image or sequence of images
montage Create a composite image (in a grid) from separate images

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.
