\section{\class{wxMask}}\label{wxmask}
This class encapsulates a monochrome mask bitmap, where the masked area is black and
-the unmasked area is white.
+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.

A mask may be associated with a \helpref{wxBitmap}{wxbitmap}. It is used in \helpref{wxDC::Blit}{wxdcblit} when
Default constructor.
-\func{}{wxMask}{\param{const wxBitmap\& }{bitmap}}
+\func{}{wxMask}{\param{const \helpref{wxBitmap}{wxbitmap}\& }{bitmap}}
Constructs a mask from a monochrome bitmap.
-\func{}{wxMask}{\param{const wxBitmap\& }{bitmap}, \param{const wxColour\& }{colour}}
+\pythonnote{This is the default constructor for wxMask in wxPython.}
+
+\func{}{wxMask}{\param{const \helpref{wxBitmap}{wxbitmap}\& }{bitmap}, \param{const \helpref{wxColour}{wxcolour}\& }{colour}}
Constructs a mask from a bitmap and a colour that indicates the background.
+\pythonnote{wxPython has an alternate wxMask constructor matching this
+form called {\tt wxMaskColour}.}
