FillPoly

Fill interior of a Polygon with specified pattern

#include <Quickdraw.h> Quickdraw

void FillPoly(thePoly, thePat );

PolyHandle thePoly ; handle of polygon to fill

PatPtr thePat ; address of an 8-byte Pattern structure

FillPoly fills all pixels enclosed by the line segments of a polygon with a

specified pattern. The transfer mode is patCopy, overwriting all bits within

the region.

thePoly is a handle leading to a variable-length Polygon structure. It is

typically a value obtained via OpenPoly.

thePat is the address of an 8-byte Pattern structure. It may be one of the

global patterns (black, white, gray, ltGray, or dkGray), or a pattern

read from a resource, or a pattern created by the application. See

PenPat for examples of obtaining or creating a pattern.

Notes: The interior of the polygon is treated as a region, even if it is not a closed

structure. The pattern overwrites the entire region, including the output of

any previously- executed "frame" operation. As with all pattern operations,

the top-left of the pattern is aligned at a multiple of 8 dots from local

coordinate (0,0).

FillPoly doesn't change the pen position. The GrafPort's pen pattern, pen

mode and background pattern are ignored.

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.
