NAME

6       wxMask - Functions for wxMask class
7

DESCRIPTION

9       This class encapsulates a monochrome mask bitmap, where the masked area
10       is black and the unmasked area is white.
11
12       When associated with a bitmap and drawn in a device  context,  the  un‐
13       masked  area  of the bitmap will be drawn, and the masked area will not
14       be drawn.
15
16       Note: A mask can be associated also with a bitmap with an alpha channel
17       but  drawing  such bitmaps under wxMSW may be slow so using them should
18       be avoided if drawing performance is an important factor.
