- 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). |
If the function succeeds, the return value is the handle to the region.
If the function fails, the return value is zero. |
