1. Image reduction: ? Alternative line reduction ? Fractal linear reduction to reduce images to any smaller size 2. Use two images to perform image enlargement: ? Pixel replication ? Nearest enlargement ? Bilinear interpolation ? Bicubic interpolation ? Fractal linear expansion to expand images to any larger size 3. Perform negative image operation ? On gray images ? On color images(1. Image reduction. 2. Use two images to perform image enlargement. 3. Perform negative image operation.)

Programming Windows with MFC by Jeff Prosise, Jeff Prosise. The production of this book required the efforts of many people, but two in particular deserve to be singled out for their diligent, sustained, and unselfish efforts. Sally Stickney, the book s principal editor, navigated me through that minefield called the English language and contributed greatly to the book s readability.
