Origin Property

Summary

Origin (top left point), in pixels, of the overlay image.

Syntax

Objective-C

C++/CLI

Java

Python

public LeadPoint Origin { get; set; }

@property (nonatomic, assign) LeadPoint origin

public LeadPoint getOrigin(); 
public void setOrigin( 
   LeadPoint leadPoint 
);

public: 
property LeadPoint Origin { 
   LeadPoint get(); 
   void set (    LeadPoint ); 
}

Origin # get and set (RasterOverlayAttributes)

Property Value

A LeadPoint that specifies the origin (top left point), in pixels, of the overlay image.

Remarks

This origin is relative to the top left point of the displayed main image. This is independent of the main image view perspective.

For more information, refer to Overlay Overview.
