Order Property

Summary

Gets or sets a value indicating the color order if the output image will be 24-bit.

Syntax

Objective-C

C++/CLI

Java

Python

public RasterByteOrder Order { get; set; }

@property (nonatomic, assign) LTRasterByteOrder order;

public RasterByteOrder getOrder(); 
public void setOrder( 
   RasterByteOrder rasterByteOrder 
);

public: 
property RasterByteOrder Order { 
   RasterByteOrder get(); 
   void set (    RasterByteOrder ); 
}

Order # get and set (WindowLevelCommand)

Property Value

Value indicating the color order if the output image will be 24-bit. If the LookupTable property is null, this property is ignored.
