Yeah sure. But let's start with something simple and ugly :-) > > The third big problem will be images. But at the moment I don't want to > > think too far.

Well, the situation is not as easy as that. First thing is we have BufferedImages (or RenderedImages for that matter), which should indeed be relativly easy. OTOH we have other images (I call them server-side-images, like offscreen images in the X-Server), which must be rendered first. Then you must take into account that the transform can scale, shear and rotate your pixel data and things start to become complicated... BTW: Thanks for the BasicStroke code. I will try it out with my Graphics2D impl and if I get something working, I'll check it in.
