Stroking with a paint tool is implemented in gimppaintcore-stroke.c, by gimp_paint_core_stroke() or gimp_paint_core_stroke_boundary(), which are very similar. Each of these functions calls: gimp_paint_core_start() gimp_paint_core_paint() gimp_paint_core_interpolate() gimp_paint_core_finish() gimp_paint_core_cleanup() And each of those requires an attached drawable. Furthermore, each of them is actually a virtual function (mostly), implemented differently by each paint tool. And at least some of those object methods will break if you don't have an attached drawable. So I don't see how to make this work on anything other than an attached drawable by any sort of simple refactoring. It would require a major rewrite of the paint core code, and that's some of the worst code in all of GIMP to mess around with. -- Bill
