GraphicsMagick Utilities

GraphicsMagick provides a powerful command line utility gm, which may be used to access all GraphicsMagick functions. Gm uses a consistent set of options (see options documentation).

The available commands are as follows:

animate Animate a sequence of images
batch Executes an arbitary number of utility commands
