I have some experimental stuff working. The strategy is to use a subclass of BitBltCanvas called HybridCanvas, that holds a VectorCanvas in an instance variable. This means that vector graphics morphs can be added to the world just like regular morphs. I had to do many changes to the way that damage regions are handled, etc. It is kind of working, but not without some hiccups, and maybe I'd change things again. So, this is not yet ready for integration. The code is attached. To test this you'll need a bit of patience. It includes 25 files! Also, it works reasonably well (without a VectorGraphics plugin!) in a rather fast machine. A slow machine might make it unusable. The procedure is: - Pull repos - Start Cuis. Don’t use an image you care about! - Install Updates - Feature require: 'VectorGraphics' - Open FileList on VGExperiments. Sort by name. Install each of the 25 files, in name order. - Close all windows. - Open a Workspace. - evaluate each of the following lines self runningWorld setCanvas: (HybridCanvas onForm: Display). "set hybrid canvas" self runningWorld canvas class. "validate canvas updated" a _ EllipseMorph2 new openInWorld. b _ EllipseMorph3 new. c _ EllipseMorph4 new. a addMorph: b. b morphPosition: 100@0. a addMorph: c. c morphPosition: -100@0. Then you can do stuff like c stopStepping c startStepping Try the halo grow handle, etc. Browse a bit the new EllipseMorph classes. These new classes _only_ now how to draw themselves. They don't include #morphContainsPoint: or #morphBoundsInWorld logic at all. Also check that the moment you modify the #drawOn: method, everything works as expected. The idea is to make writing new morphs as simple as possible, with the framework handling the complex parts. I plan to keep working on this, until it is mature enough for integration in Cuis.

PolygonMorph is more like M3Exp01Morph, M3Exp02Morph and M3Exp03Morph. But these also don't work well yet. Damage areas are not reported correctly and morphContainsPoint: doesn't work either. The VectorGraphicsPasteUpMorph was just a hack to let you play with vector graphics drawing, but I guess it is time to clean it up, make it usable, and integrate it. Then it will make sense to start building things like PolygonMorph in a clean style. Please give me a few days to work on this.
