This project uses only Windows API to implement basic painting.

• Core technologies used: Windows GDI
• Algorithms involved: Analyze differences between old and current bitmaps and push them into stacks to save; to undo/redo changes, pop them out of the stacks and draw on current bitmap

Simple Paint can do the following things currently:

1. Paint/Erase/Fill/Pick color with mouse or by touching screen (press [Esc] key to cancel)
2. Select pen/eraser size
3. Change canvas size
4. Customize colors
5. Undo/Redo operations
6. Save images as 24-bit bitmap files (*.bmp)
