I'm sorry, I'm developing a C plugin (tried Scheme first and it was DOG slow). Is there a C equivalent? All I'm seeing is gimp-paintbrush-register.
Funny, a search for "gimp c api line" turns up this thread. :-) Going further, searching for "gimp plugin api draw line" and restricting to developer.gimp.org turns up GDK drawing primitives. So it sounds like the best way to proceed is to wrap the pixel data into a GdkPixbuf and use GDK to draw into it. Figured there might be a more straightforward way to go from a GimpDrawable to a GdkDrawable (since it is after all the "GIMP Drawing Kit"). Hmm, and there's a GimpCanvas object, but that doesn't seem to be a plugin thing.
