SketchDemo The Animation Sketch Pad is a simple program for demonstration to new NeXT programmers. It can help in understanding compositing . It is not intended as a serious drawing tool, but maybe it will inspire some serious effort. This program and its source are in the Public Domain. No claims are made to the correctness or usefulness of this code. Comments are welcomed to help make this a better demo program. The code is intended to provide clear, correct use of the App Kit, rather than fast, but dirty code. The basic Idea is that you have a sketch pad of semi-transparent paper in front of you. You can draw on a page, and then flip to a prior page, or next page. When you move to a new page, the pages previous to it are dispayed "under" the new one using compositing operations. Carl F.
