21.7 GRAPHICS

21.7.1 Bit map editor

Microsoft has provided a bitmap editor in Visual C++ package. Bit Map Editor is a general graphical utility, useful in creating very small pictures. Let us develop a simple bitmap editor ourselves.

Problem: Write a program to edit a bitmap.

Solution: Any medium size programming task needs proper specifications. Let us define on our own specifications for this program.

1. It should be a monochrome bitmap editor.
2. Size should be 16 by 16 pixels.
3. While editing keys assignments are as follows:

   Draw        -> Any normal key

   Erase        -> Space bar

   End Edit   -> Escape

See Program 21.20.
