CreatePolyPolygonRgn

The CreatePolyPolygonRgn function creates a region consisting of a series of polygons. The polygons can overlap.

HRGN CreatePolyPolygonRgn(

CONST POINT *lppt,	// pointer to array of points
CONST INT *lpPolyCounts,	// pointer to array that contains vertex counts
int nCount,	// number of integers in array of vertex counts
int fnPolyFillMode	// polygon fill mode
);

Parameters

lppt

Points to an array of POINT structures that define the vertices of the polygons. The polygons are specified consecutively. Each polygon is presumed closed and each vertex is specified only once.

lpPolyCounts

Points to an array of integers, each of which specifies the number of points in one of the polygons in the array pointed to by lppt.

nCount

Specifies the total number of integers in the array pointed to by lpPolyCounts.

fnPolyFillMode

Specifies the fill mode used to determine which pixels are in the region. This parameter can be one of the following values:

Value	Meaning
ALTERNATE	Selects alternate mode (fills area between odd-numbered and even-numbered polygon sides on each scan line).
WINDING	Selects winding mode (fills any region with a nonzero winding value).

For more information about these modes, see the SetPolyFillMode function.

Return Values

If the function succeeds, the return value is the handle to the region.

If the function fails, the return value is zero.
