The LeadRect structure to combine with this RasterRegion.
combineMode
One of the RasterRegionCombineMode enumeration members that describes the combine method to use. This cannot be RasterRegionCombineMode.AndNotImage or RasterRegionCombineMode.AndNotRegion. Using any of these combine method will result in an exception.
For more information, refer to RasterRegionCombineMode.
