About Script-Fu

• Almost every large program benefits from having an associated programming language so that users can automate tasks.
• The first associated language for the Gimp was Script-Fu, a variant of Scheme based on SIOD, yet another variant of Scheme.
  • Some of the things you want to do in Scheme are not available in Script-Fu.
  • Script-Fu is not nearly as friendly.
• Almost everything you can do by hand in the Gimp, you can write a Script-Fu command or procedure to do.
• Rather than talking a lot about this issue, I'll let you play.
