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.
destinationRect
LeadRect structure that contains the destination rectangle.
opacity
Opacity value used when combining the areas from the source and affected images. This value is between 0 and 255.
Run the AlphaBlendCommand on an image.
