Windows HRGN object.
System.Drawing.Graphics object where the frame is to appear.
Zero-index of the frame to display. Possible values are from 0 to MaxRegionFrameIndex. You can animate the region frame by cycling between these values.
If the region includes non-contiguous shapes, each shape is outlined. The outline, itself, is inside the region.
This method is designed to produce an animated frame, which you can implement by calling the method with a timer event that cycles through the possible frame types.
