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.
Initializes a new Leadtools.ImageProcessing.Effects.DisplacementCommand class object with explicit parameters. Supported in Silverlight, Windows Phone 7

Syntax

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

Example

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