)

public:
DisplacementCommand( 
   RasterImage^ displacementMapImage,
   int horizontalFactor,
   int verticalFactor,
   RasterColor fillColor,
   DisplacementCommandFlags flags
)

Parameters

displacementMapImage: The displacement map image.
horizontalFactor: Horizontal displacement factor, in percent of the image dimensions. The valid range is from 0 to 100.
verticalFactor: Vertical displacement factor, in percent of the image dimensions. The valid range is from 0 to 100.
fillColor: The RasterColor value that specifies the fill color for any exposed areas.
flags: Flags that indicate how to handle exposed areas, and the way to use the displacement map image.
