Paper Trace by Robert Rayment. This consists of an image sheet (Loaded image), a translucent tracing sheet(Faded image to draw on) and a white paper sheet (The actual tracing that can be saved as a 2 color(B/W) BMP). The screenshot explains more. To show the method I've kept it simple in that large pictures are scaled down, avoiding scrollng code. Zip 36 KB.
