BMP Window

Allows a second .BMP to be viewed through a fuzzy window in the first one. BMP Window application was designed to allow a second .BMP to be viewed through a fuzzy window in the first one.

Taking two picture files of any size, this program creates a smooth circular window in the "top" picture, allowing you to see the "underlying" picture through the window.

The window is moved around using the mouse. I've only written the program as Assembly Language enhanced, since the window was very jerky under pure BASIC. With assembler, it's perfectly smooth, making 129,600 calls to a 200-instruction Assembly Routine every time the window moves by just one pixel!
