ShiftDataCommand Constructor(int,int,int,int)

Summary

Initializes a new ShiftDataCommand class object with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public ShiftDataCommand( 
   int sourceLowBit, 
   int sourceHighBit, 
   int destinationLowBit, 
   int destinationBitsPerPixel 
)

- (instancetype)initWithSourceLowBit:(NSUInteger)sourceLowBit sourceHighBit:(NSUInteger)sourceHighBit destinationLowBit:(NSUInteger)destinationLowBit destinationBitsPerPixel:(NSUInteger)destinationBitsPerPixel NS_DESIGNATED_INITIALIZER;

public ShiftDataCommand( 
   int sourceLowBit, 
   int sourceHighBit, 
   int destinationLowBit, 
   int destinationBitsPerPixel 
);

public: 
ShiftDataCommand(  
   int sourceLowBit, 
   int sourceHighBit, 
   int destinationLowBit, 
   int destinationBitsPerPixel 
)

__init__(self,sourceLowBit,sourceHighBit,destinationLowBit,destinationBitsPerPixel) # Overloaded constructor

Parameters

sourceLowBit
Position of the start bit that will construct the mask. The position is a zero-based number. This parameter accepts only positive values.

sourceHighBit
Position of the end bit. This is inclusive (it is part of the mask). The value should not be less than sourceLowBit. You can also pass -1, which is interpreted as "highest bit" (SourceImage->BitsPerPixel - 1). This parameter accepts only positive values.

destinationLowBit
The bit position where the selected mask will be copied into the destination image. This parameter accepts only positive values.

destinationBitsPerPixel
Bits per pixel for the destination image. The allowed values are 8, 12, or 16.

Example

Run the ShiftDataCommand on an image.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
 
public void ShiftDataConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg")); 
 
   // Prepare the command 
   ShiftDataCommand command = new ShiftDataCommand(2, 6, 3, 8); 
   // Move 5 bits starting from bit 2 into the high bits of the affected image. 
   command.Run(image); 
   codecs.Save(command.DestinationImage, Path.Combine(LEAD_VARS.ImagesDir, "ShiftDataResult.bmp"), RasterImageFormat.Bmp, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
