Edge Scan


Scan for the edge of a bitmap to create a transparent region. Scans the edge of a bitmap and creates a polygon region. Use it to create odd-shaped forms. It does not scan for "internal" transparent areas - only the edge. The background color needs to be unique. Also shows how to allow form dragging without a caption.
