Public Sub AddGdiPlusRegionToRegion( _
   ByVal xform As RasterRegionXForm, _
   ByVal region As Region, _
   ByVal combineMode As RasterRegionCombineMode _
) 
Visual Basic (Usage) Copy Code
Dim instance As RasterImage
Dim xform As RasterRegionXForm
Dim region As Region
Dim combineMode As RasterRegionCombineMode
 
instance.AddGdiPlusRegionToRegion(xform, region, combineMode)

)
C++/CLI  
public:
void AddGdiPlusRegionToRegion( 
   RasterRegionXForm^ xform,
   Region region,
   RasterRegionCombineMode combineMode
)
