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.
