SourcePoint Property
See Also  Example
Leadtools.ImageProcessing.Effects Namespace > AlphaBlendCommand Class : SourcePoint Property



Gets or sets the point structure that contains the origin of the source rectangle.

Syntax

Visual Basic (Declaration) 
Public Property SourcePoint As Point
Visual Basic (Usage)Copy Code
Dim instance As AlphaBlendCommand
Dim value As Point
 
instance.SourcePoint = value
 
value = instance.SourcePoint
C# 
public Point SourcePoint {get; set;}
C++/CLI 
public:
property Point SourcePoint {
   Point get();
   void set (Point value);
}

Return Value

Point structure that contain the origin of the source rectangle. the Width and Height are the same Width and Height for the destination rectangle.

Example

Run the AlphaBlendCommand on an image.
