CreatePolyPolygonRgn

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

VB4-32,5,6
Declare Function CreatePolyPolygonRgn Lib "gdi32" Alias "CreatePolyPolygonRgn" (lpPoint As POINTAPI, lpPolyCounts As Long, ByVal nCount As Long, ByVal nPolyFillMode As Long) As Long

VB.NET
System.Drawing.Region

Operating Systems Supported
Requires Windows NT 3.1 or later; Requires Windows 95 or later

Library
Gdi32

Parameter Information
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:
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).

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

If the function fails, the return value is zero.
