117This class encapsulates a monochrome mask bitmap, where the masked area is black
118and the unmasked area is white. When associated with a bitmap and drawn in a device
119context, the unmasked area of the bitmap will be drawn, and the masked area will
120not be drawn.
121
122This example shows not only how to create a Mask, but the effects of the Device
123Context (dc) <code>Blit()</code> method's logic codes.
