Java
Public Function New( _ 
   ByVal sourceImage As RasterImage, _ 
   ByVal sourcePoint As LeadPoint, _ 
   ByVal destinationRectangle As LeadRect, _ 
   ByVal maskImage As RasterImage, _ 
   ByVal maskSourcePoint As LeadPoint _ 
) 
- (instancetype)initWithSourceImage:(LTRasterImage *)sourceImage 
                        sourcePoint:(LeadPoint)sourcePoint 
               destinationRectangle:(LeadRect)destinationRectangle 
                          maskImage:(LTRasterImage *)maskImage 
                    maskSourcePoint:(LeadPoint)maskSourcePoint 
public FeatherAlphaBlendCommand( 
   RasterImage sourceImage,  
   LeadPoint sourcePoint,  
   LeadRect destinationRectangle,  
   RasterImage maskImage,  
   LeadPoint maskSourcePoint 
) 

Parameters

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.

Example

Run the FeatherAlphaBlendCommand on an image.
