Public Class ColorLevelCommandData

'Usage
 
Dim instance As ColorLevelCommandData

public sealed class ColorLevelCommandData

@interface LTColorLevelCommandData : NSObject

public class ColorLevelCommandData

function Leadtools.ImageProcessing.Color.ColorLevelCommandData()

public ref class ColorLevelCommandData

The value of the MaximumInput property must be greater than the value of the MinimumInput property by at least 2.
If MinimumOutput > MaximumOutput then the image's shadows and highlights will be inverted for the given channel.
This class is used by the ColorLevelCommand class.
This class does not support 32-bit grayscale images.
