NAME
wxMask - Functions for wxMask class
DESCRIPTION
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.
