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

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
 
public void CreateGrayscaleImageCommandExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
	string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1_CreateGrayscaleImage.bmp"); 
 
	// Load the source image from disk 
	RasterImage srcImage = codecs.Load(srcFileName); 
 
	// Create a grayscale image 
	CreateGrayscaleImageCommand cmd = new CreateGrayscaleImageCommand(); 
	cmd.BitsPerPixel = 16; 
	cmd.LowBit = 0; 
	cmd.HighBit = 15; 
	cmd.Run(srcImage); 
 
	RasterImage destImage = cmd.DestinationImage; 
 
	// Save the image to disk 
	codecs.Save( 
	   destImage, 
	   destFileName, 
	   RasterImageFormat.Bmp, 
	   16); 
 
	// Clean up 
	destImage.Dispose(); 
	srcImage.Dispose(); 
	codecs.Dispose(); 
}
