Public Function New( _ 
   ByVal displacementMapImage As RasterImage, _ 
   ByVal horizontalFactor As Integer, _ 
   ByVal verticalFactor As Integer, _

   ByVal flags As DisplacementCommandFlags _ 
) 
- (instancetype)initWithDisplacementMapImage:(LTRasterImage *)displacementMapImage 
                            horizontalFactor:(NSUInteger)horizontalFactor 
                              verticalFactor:(NSUInteger)verticalFactor 
                                   fillColor:(LTRasterColor *)fillColor 
                                       flags:(LTDisplacementCommandFlags)flags 
public DisplacementCommand( 
   RasterImage displacementMapImage,  
   int horizontalFactor,  
   int verticalFactor,  
   RasterColor fillColor,  
   int 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.

Example

Run the DisplacementCommand on an image and applies the Displace Map filter.
