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.
