Extending the Gimp with new functionality is - uhm - easy. Since The GIMP is Freeware there are lots of code samples available. However, this code is not really thoroughly documented and you need to twist your brain a while until you figure out what e.g. a GimpPixelRegion is. This talk explains the basic concepts on writing Scripts and Plug-Ins for The GIMP. We will walk through a sample script and a sample plug-in. The audience is encouraged to ask questions.
