public FeatherAlphaBlendCommand( 
   RasterImage sourceImage,
   LeadPoint sourcePoint,
   LeadRect destinationRectangle,
   RasterImage maskImage
)

'Declaration
 
Public Function New( _
   ByVal sourceImage As RasterImage, _
   ByVal sourcePoint As LeadPoint, _
   ByVal destinationRectangle As LeadRect, _
   ByVal maskImage As RasterImage _
)

'Usage
 
Dim sourceImage As RasterImage
Dim sourcePoint As LeadPoint
Dim destinationRectangle As LeadRect
Dim maskImage As RasterImage
 
Dim instance As New FeatherAlphaBlendCommand(sourceImage, sourcePoint, destinationRectangle, maskImage)

public FeatherAlphaBlendCommand( 
   RasterImage sourceImage,
   LeadPoint sourcePoint,
   LeadRect destinationRectangle,
   RasterImage maskImage
)

- (id)initWithSourceImage:(LTRasterImage*)sourceImage 
              sourcePoint:(LeadPoint)sourcePoint 
     destinationRectangle:(LeadRect)destinationRectangle 
                maskImage:(LTRasterImage*)maskImage;

public FeatherAlphaBlendCommand(
   RasterImage sourceImage, 
   LeadPoint sourcePoint, 
   LeadRect destinationRectangle, 
   RasterImage maskImage
)

function FeatherAlphaBlendCommand( 
   sourceImage ,
   sourcePoint ,
   destinationRectangle ,
   maskImage 
)

public:
FeatherAlphaBlendCommand( 
   RasterImage^ sourceImage,
   LeadPoint sourcePoint,
   LeadRect destinationRectangle,
   RasterImage^ maskImage
)

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.
