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.
