Description

Arguments

pGC

points to an nfbGCOps(D4nfb) structure. From this structure you can extract the planemask, alu, and color for the polygons. See the sample code in FillSpans(D3nfb) for how this is done. All drawing routines that have a pGC pointer passed as the first parameter need to extract this information the same way.

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 pDraw->pScreen. Your screen private is connected to the bottom of ScreenRec.

pppt

points to the first in a series of DDXPointRec(D4nfb) structures that contain the starting x and y coordinates for each polygon.

pnpts

points to an array of points that define the vertices of the polygon.

npgns

defines the number of points in the polygon.

shape

indicates the shape of the polygon. Convex shapes are special cases. See X.h for more information.

fill

defines the fill style.
