   AutoColorLevelCommandType type,  
   int flag 
)

public: 
AutoColorLevelCommand(  
   int blackClip, 
   int whiteClip, 
   AutoColorLevelCommandType type, 
   AutoColorLevelCommandFlags flag 
)

Parameters

blackClip
Value that represents the percentage of black pixels to clip from the image, in hundredths of a percent. Valid values range from 0 to 10000 (which represents 100). Best results are found using 0.3 to 0.9 . The default is 50, which indicates to clip 0.5 of the black pixels.

whiteClip
Value that represents the percentage of white pixels to clip from the image, in hundredths of a percent. Valid values range from 0 to 10000 (which represents 100). The default is 50, which indicates to clip 0.5 of the white pixels.

type
Value that indicates the type of leveling to perform.

flag
Flag that indicates whether the method will process the image or not.

Example

Run the AutoColorLevelCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
public void AutoColorLevelConstructorExample_S2() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Image1.jpg")); 
 
   // Prepare the command 
   AutoColorLevelCommand command = new AutoColorLevelCommand(50, 500, AutoColorLevelCommandType.Intensity, AutoColorLevelCommandFlags.None); 
   // Apply "Auto Leveling" to the image. 
   command.Run(image); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS21\Resources\Images"; 
}

Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing.Color 
 
Public Sub AutoColorLevelConstructorExample_S2() 
   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Image1.jpg")) 
 
   ' Prepare the command 
   Dim command As AutoColorLevelCommand = New AutoColorLevelCommand(50, 500, AutoColorLevelCommandType.Intensity, AutoColorLevelCommandFlags.None) 
   ' Apply "Auto Leveling" to the image. 
   command.Run(leadImage) 
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24) 
 
End Sub
