public class BalanceColorsCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration

Public Class BalanceColorsCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As BalanceColorsCommand

public sealed class BalanceColorsCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTBalanceColorsCommand : LTRasterCommand

public class BalanceColorsCommand extends RasterCommand

function Leadtools.ImageProcessing.Color.BalanceColorsCommand()

public ref class BalanceColorsCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

For each pixel in the image, the red value is modified using the values in the RedFactor property. This generates an intermediate red value, an intermediate green value and an intermediate blue value.
For each pixel in the image, the green value is modified using the values in the GreenFactor property. This generates an intermediate red value, an intermediate green value and an intermediate blue value.
For each pixel in the image the blue value is modified using the values in the BlueFactor property. This generates an intermediate red value, an intermediate green value and an intermediate blue value.
The intermediate red values are added to generate the new red value for the pixel. The intermediate green values are added to generate the new green value for the pixel and the intermediate blue values are added to generate the new blue value for the pixel. This triplet forms the new RGB value for the pixel.
The BalanceColorCommandFactor class has three components of type double: ToRed, ToGreen and ToBlue. The possible values of each component must be within the range: 0.0 - 100.0.
This class supports 48 and 64-bit colored images.
This method does not support signed data images.
This command does not support 32-bit grayscale images.
