public:
FeatherAlphaBlendCommand( 
   RasterImage sourceImage,
   Point sourcePoint,
   Rectangle destinationRectangle,
   RasterImage maskImage,
   Point maskSourcePoint
)

Parameters

sourceImage

RasterImage object that references the source image.

sourcePoint

Point structure that contains the origin of the source rectangle. The width and height are the same width and height for the destination rectangle.

destinationRectangle

Rectangle 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

Point 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.

Run the FeatherAlphaBlendCommand on an image.
