ContrastBrightnessIntensityCommand Constructor(int,int,int)

Summary
Initializes a new ContrastBrightnessIntensityCommand class object with explicit parameters.
Syntax
C#
Objective-C
C++/CLI
Java
Python
- (instancetype)initWithContrast:(NSInteger)contrast brightness:(NSInteger)brightness intensity:(NSInteger)intensity NS_DESIGNATED_INITIALIZER ; 
public ContrastBrightnessIntensityCommand( 
   int contrast, 
   int brightness, 
   int intensity 
); 
public: 
ContrastBrightnessIntensityCommand(  
   int contrast, 
   int brightness, 
   int intensity 
) 
__init__(self,contrast,brightness,intensity) # Overloaded constructor 

Parameters

contrast
Value that refers to the histogram stretching amount. It represents the amount of contrast change. The contrast ranges from -1000 to +1000. This value is divided internally by 1000. A positive value increases the contrast whereas a negative value decreases the contrast.

brightness
Value that refers to colors intensities scale factor. It indicates the amount of brightness change. The brightness ranges from -1000 to 1000. This value is divided internally by 1000. A positive value increases (or lightens) the brightness of the image image. A negative value decreases (or darkens) the brightness of the image image.

intensity
Value that refers to colors intensities shifting amount. It indicates the amount of intensity change. The intensity ranges from -1000 to +1000. This value is divided internally by 1000. A positive value lightens the brightness pixels whereas a negative value darkens the brightness pixels.

Example

Run the ContrastBrightnessIntensityCommand on an image.

Java

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   ContrastBrightnessIntensityCommand command = new ContrastBrightnessIntensityCommand(-146, 200, 310);
