Paints the interior of the specified geometry.

(See also unamanged API documentation)



1.If the opacityBrush parameter is not null, the alpha value of each pixel of the mapped opacityBrush is used to determine the resulting opacity of each corresponding pixel of the geometry. Only the alpha value of each color in the brush is used for this processing; all other color information is ignored. The alpha value specified by the brush is multiplied by the alpha value of the geometry after the geometry has been painted by brush.  

2.This method doesn't return an error code if it fails.
