   RasterRegionXForm^ xform,
   RasterImage^ maskImage,
   RasterRegionCombineMode combineMode
) 

Parameters

xform

RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates.

maskImage

The 1-bit black-and-white RasterImage used as a mask.

combineMode

The action to take regarding the existing image region, if one is defined.

To update an existing region, you specify how the new region is to be combined with the existing one using the combineMode parameter. For more information, refer to RasterRegionCombineMode.
