ErasePoly
ErasePoly
Fill polygon with background pattern PolyHandle thePoly ; handle of polygon to erase
ErasePoly fills the interior of a polygon using the background pattern of the current GrafPort and the srcCopy transfer mode. thePoly is a handle that leads to a variable-length Polygon structure. It is typically a value obtained via OpenPoly.
Notes: ErasePoly is functionally equivalent to: The pen position is not changed by this function.
As with all Quickdraw drawing, the output is clipped to the intersection of
the current GrafPort's bitMap boundary rectangle, the port rectangle, clipping region, and visible region.
