Summary

Initializes a new instance of the CreateGrayscaleImageCommand class with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public CreateGrayscaleImageCommand( 
   int bitsPerPixel, 
   int lowBit, 
   int highBit 
)

- (instancetype)initWithBitsPerPixel:(NSInteger)bitsPerPixel  
                              lowBit:(NSInteger)low  
                             highBit:(NSInteger)high

public CreateGrayscaleImageCommand( 
   int bitsPerPixel,  
   int lowBit,  
   int highBit 
)

public: 
CreateGrayscaleImageCommand(  
   int bitsPerPixel, 
   int lowBit, 
   int highBit 
)

__init__(self,bitsPerPixel,lowBit,highBit) # Overloaded constructor

Parameters

bitsPerPixel
Value that indicates the number of bits for the destination image. Valid values are 8, 12, or 16.

lowBit
Value that indicates the low bit used for window leveling when the bitsPerPixel is 12 or 16.

highBit
Value that indicates the high bit used for window leveling when the bitsPerPixel is 12 or 16.

Example

	// Load the source image from disk 
	RasterImage srcImage = codecs.Load(srcFileName); 
 
	// Create a grayscale image
