CreatePolygonRgn info  Overview  Group

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

   );

Parameters

lppt
Points to an array of POINT structures that define the vertices of the polygon. The polygon is presumed closed. Each vertex can be specified only once.
cPoints
Specifies the number of points in the array.
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 NULL. To get extended error information, call GetLastError.
