Syntax

Objective-C

C++/CLI

Java

Python

public int MinimumInput { get; set; }

@property (nonatomic, assign) NSInteger minimumInput;

public int getMinimumInput(); 
public void setMinimumInput( 
   int intValue 
);

public: 
property int MinimumInput { 
   int get(); 
   void set (    int ); 
}

MinimumInput # get and set (ColorLevelCommandData)

Property Value

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.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void ColorLevelCommandExample() 
{ 
   // 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(); 
   ColorLevelCommandData master = new ColorLevelCommandData(); 
   //Specify Image levels 
   blue.MinimumInput = 20; 
   blue.MaximumInput = 200; 
   blue.MinimumOutput = 0; 
   blue.MaximumOutput = 255; 
   blue.Gamma = 100; 
   // Master will cause the image to be Inversed 
   master.MinimumInput = 0; 
   master.MaximumInput = 255; 
   master.MinimumOutput = 255; 
   master.MaximumOutput = 0; 
   master.Gamma = 100; 
   // Level the Blue and Master channels 
   ColorLevelCommand command = new ColorLevelCommand(master, null, null, blue, 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";
