CreateEllipticRgnIndirect function

The CreateEllipticRgnIndirect function creates an elliptical region.

Syntax


HRGN CreateEllipticRgnIndirect(
  _In_  const RECT *lprc
);

Parameters

lprc [in]

Pointer to a RECT structure that contains the coordinates of the upper-left and lower-right corners of the bounding rectangle of the ellipse in logical units.

Return value

If the function succeeds, the return value is the handle to the region.

If the function fails, the return value is NULL.

Remarks

When you no longer need the HRGN object, call the DeleteObject function to delete it.

A bounding rectangle defines the size, shape, and orientation of the region: The long sides of the rectangle define the length of the ellipse's major axis; the short sides define the length of the ellipse's minor axis; and the center of the rectangle defines the intersection of the major and minor axes.
