Syntax

Objective-C

C++/CLI

Java

Python

public LeadPoint SourcePoint { get; set; }

@property (nonatomic, assign) LeadPoint sourcePoint;

public LeadPoint getSourcePoint(); 
public void setSourcePoint( 
   LeadPoint leadPoint 
);

property LeadPoint SourcePoint { 
   LeadPoint get(); 
   void set (    LeadPoint ); 
}

SourcePoint # get and set (AlphaBlendCommand)

Property Value

LeadPoint 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.
