The CreatePolygonRgn function creates a polygonal region.
HRGN CreatePolygonRgn(
CONST POINT *lppt, |
// pointer to array of points |
int cPoints, |
// number of points in array |
int fnPolyFillMode |
// polygon-filling mode |
); |
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.
If the function succeeds, the return value is the handle to the region.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
