);

public: 
ColorLevelCommandData(  
   int minimumInput,

   int gamma

__init__(self,minimumInput,maximumInput,minimumOutput,maximumOutput,gamma) # Overloaded constructor

Parameters

minimumInput
Value that specifies the image's shadows to be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit images. Any value greater than or equal to this will be considered a shadow and will be remapped to the value in MinimumOutput.

maximumInput
Value that specifies the image's highlights to be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit images. Any value greater than or equal to this will be considered a highlight and will be remapped to the value in MaximumOutput.

minimumOutput
Value that specifies the value to which the shadows will be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit images.

maximumOutput
Value that specifies the value to which the highlights will be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit images.

gamma
Value that represents the gamma value. This value is used to modify the midtones of the image. The value in this member is a 100 times the actual value. Therefore, if uGamma = 167 then the actual gamma value is 1.67. Likewise, if you want to use a gamma of 1.75, set this member to 175. The default value is DEFAULT_GAMMA, which is 100 (actual gamma value of 1.00) which does not change the gamma value of the image.

Example

Run the ColorLevelCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void ColorLevelCommandDataConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   ColorLevelCommandData blue = new ColorLevelCommandData(0, 255, 255, 0, 100); 
   ColorLevelCommandData master = new ColorLevelCommandData(20, 200, 0, 255, 100); 
   ColorLevelCommandData red = new ColorLevelCommandData(0, 255, 0, 255, 100); 
   ColorLevelCommandData green = new ColorLevelCommandData(0, 255, 0, 255, 100); 
 
   // Level the Blue and Master channels 
   ColorLevelCommand command = new ColorLevelCommand(); 
   command.Blue = blue; 
   command.Red = red; 
   command.Green = green; 
   command.Master = master; 
   command.Flags = ColorLevelCommandFlags.Blue | ColorLevelCommandFlags.Master; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
