Macros
OMA commands can be bundled into batch files and executed as if they were another OMA command. The contributed OMA macros are either:

  1. Examples that demonstrate how to use loops and arithmetic within OMA.
  2. Comprise batches of commands that can be run without arguments and are effectively new image processing commands.
