BitPosition Property

Summary

Gets or sets the corresponding bit plane associated with an overlay

Syntax

Objective-C

C++/CLI

Java

Python

public int BitPosition { get; set; }

@property (nonatomic, assign) NSUInteger bitPosition

public int getBitPosition(); 
public void setBitPosition( 
   int intValue 
);

public: 
property int BitPosition { 
   int get(); 
   void set (    int ); 
}

BitPosition # get and set (RasterOverlayAttributes)

Property Value

The corresponding bit plane associated with an overlay.

Remarks

This property is valid only if UseBitPlane is set to true. For more information about the bit position, refer to "Overlay Plane Module Attributes" in the DICOM standard and Overlay Overview.
