TQ3Status Q3DrawContext_SetMask (
TQ3DrawContextObject context, 
const TQ3Bitmap *mask);

A draw context object.

mask

The desired mask of the specified draw context.

DESCRIPTION

The Q3DrawContext_SetMask function sets the mask of the draw context specified by the context parameter to the bitmap specified in the mask parameter. Q3DrawContext_SetMask copies the bitmap to internal QuickDraw 3D memory, so you can dispose of the specified bitmap after calling Q3DrawContext_SetMask.
