Detailed Description

A Buffered window class (2D view mode)

Superclass for VDigitWindow (vector digitizer).

When the drawing needs to change, you app needs to call the UpdateMap() method. Since the drawing is stored in a bitmap, you can also save the drawing to file by calling the SaveToFile() method.
