View Source wxMask (wx v2.4.3)

This class encapsulates a monochrome mask bitmap, where the masked area is black and the unmasked area is white.

When associated with a bitmap and drawn in a device context, the unmasked area of the bitmap will be drawn, and the masked area will not be drawn.

Note: A mask can be associated also with a bitmap with an alpha channel but drawing such bitmaps under wxMSW may be slow so using them should be avoided if drawing performance is an important factor.
