FeatherAlphaBlendCommand Constructor(RasterImage,Point,Rectangle,RasterImage)
See Also  Example
Leadtools.ImageProcessing.Effects Namespace > FeatherAlphaBlendCommand Class > FeatherAlphaBlendCommand Constructor : FeatherAlphaBlendCommand Constructor(RasterImage,Point,Rectangle,RasterImage)



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.
Initializes a new FeatherAlphaBlendCommand class object with explicit parameters.

Syntax

Visual Basic (Declaration) 
Public Function New( _
   ByVal sourceImage As RasterImage, _
   ByVal sourcePoint As Point, _
   ByVal destinationRectangle As Rectangle, _
   ByVal maskImage As RasterImage _
)
Visual Basic (Usage)Copy Code
Dim sourceImage As RasterImage
Dim sourcePoint As Point
Dim destinationRectangle As Rectangle
Dim maskImage As RasterImage
 
Dim instance As FeatherAlphaBlendCommand(sourceImage, sourcePoint, destinationRectangle, maskImage)
C# 
public FeatherAlphaBlendCommand( 
   RasterImage sourceImage,
   Point sourcePoint,
   Rectangle destinationRectangle,
   RasterImage maskImage
)
C++/CLI 
public:
FeatherAlphaBlendCommand( 
   RasterImage sourceImage,
   Point sourcePoint,
   Rectangle destinationRectangle,
   RasterImage maskImage
)

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.

Example

Run the FeatherAlphaBlendCommand on an image.
