Syntax

public LightControlCommand( 
   int[] lowerAverage, 
   int[] average, 
   int[] upperAverage, 
   LightControlCommandType type 
)

- (instancetype)initWithLowerAverage:(nullable NSArray<NSNumber *> *)lowerAverage average:(nullable NSArray<NSNumber *> *)average upperAverage:(nullable NSArray<NSNumber *> *)upperAverage type:(LTLightControlCommandType)type NS_DESIGNATED_INITIALIZER;

public LightControlCommand( 
   int[] lowerAverage, 
   int[] average, 
   int[] upperAverage, 
   LightControlCommandType type 
);

public: 
LightControlCommand(  
   array<int>^ lowerAverage, 
   array<int>^ average, 
   array<int>^ upperAverage, 
   LightControlCommandType type 
)

__init__(self,lowerAverage,average,upperAverage,type) # Overloaded constructor

Parameters

lowerAverage
An array that contains the new average pixel value for those pixels with values between 0 and the average pixel value for the entire image. The size of the array equals one, if Type is LightControlCommandType.Yuv or LightControlCommandType.Gray, or three, if Type is LightControlCommandType.Rgb. If Type is LightControlCommandType.Rgb the first element corresponds to the new blue lower average value, the second element to the green, and the last element to the red.

average
An array that contains the new average pixel value for the entire image. The size of the array equals one, if Type is LightControlCommandType.Yuv or LightControlCommandType.Gray, or three, if Type is LightControlCommandType.Rgb. If Type is LightControlCommandType.Rgb the first element corresponds to the new blue average value, the second element to the green, and the last element to the red.

upperAverage
An array that contains the new average pixel value for those pixels with values between the average pixel value for the entire image and the highest pixel value in the image. The size of the array equals either one if Type is LightControlCommandType.Yuv or LightControlCommandType.Gray or three if Type is LightControlCommandType.Rgb where the first element corresponds to the new blue upper side average value, the second element to the green, and the last element to the red.

type
Flag that indicates which color space to remap.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void LightControlCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "dirty_barcode.jpg")); 
 
   // Prepare the command 
   int[] LowerAverage = new int[3]; 
   int[] Average = new int[3]; 
   int[] UpperAverage = new int[3]; 
   LowerAverage[0] = 100;  //for blue, gray or yuv 
   LowerAverage[1] = 120;  //for green 
   LowerAverage[2] = 80;   //for red 
   Average[0] = 210;       //for blue, gray or yuv 
   Average[1] = 210;       //for green 
   Average[2] = 210;       //for red 
   UpperAverage[0] = 255;  //for blue, gray or yuv 
   UpperAverage[1] = 255;  //for green 
   UpperAverage[2] = 255;  //for red  
   LightControlCommand command = new LightControlCommand(LowerAverage, Average, UpperAverage, LightControlCommandType.Yuv); 
   // change the lightness of the image. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
