Description

Arguments

pGC: points to an X GC structure. With routines that have a GC pointer as their first argument. The alu, planemask, and fg colors are extracted from this structure. Also, all information associated with the stipple, including a pointer to its image, is extracted from this structure.
pDraw: pointer to an X structure called DrawableRec. This pointer is only used to access your screen private data. The ScreenRec structure is pointed to by pDrawable->pScreen. Your screen private is connected to the bottom of ScreenRec.
ppt: points from which to start copying.
wpwidth: list of number of bits to copy.
npts: number of points to copy.
