BitPosition Property

Summary
Gets or sets the corresponding bit plane associated with an overlay
Syntax
C#
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.
