Public Property UnderlayImage As RasterImage
public:
property RasterImage^ UnderlayImage {
RasterImage^ get();
void set ( RasterImage^ );
}
RasterImage object that references the image to be used as the underlying image. The command will use this image to underlay the mask image. You could ignore this property effect by passing null.
Run the TextureAlphaBlendCommand on an image.
