Leadtools.ImageProcessing.Effects Namespace > FeatherAlphaBlendCommand Class > FeatherAlphaBlendCommand Constructor : FeatherAlphaBlendCommand Constructor(RasterImage,LeadPoint,LeadRect,RasterImage,LeadPoint)



sourceImage
RasterImage object that references the source image.
sourcePoint
LeadPoint structure that contains the origin of the source rectangle. The width and height are the same width and height for the destination rectangle.
destinationRectangle
LeadRect structure that contains the destination rectangle.
maskImage
RasterImage object that references the fade mask. If you want to combine the two images just with opacity set this property to null.
maskSourcePoint
LeadPoint structure that contains the origin of the mask rectangle. The width and height for the mask rectangle are the same width and height for the destination rectangle.
Initializes a new Leadtools.ImageProcessing.Effects.FeatherAlphaBlendCommand class object with explicit parameters. Supported in Silverlight, Windows Phone 7
