BrightnessFactor Property

Summary

Gets or sets the brightness factor for increasing or decreasing the brightness of the image.

Syntax

Objective-C

C++/CLI

Java

Python

public int BrightnessFactor { get; set; }

@property (nonatomic, assign) NSUInteger brightnessFactor;

public int getBrightnessFactor(); 
public void setBrightnessFactor( 
   int intValue 
);

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

BrightnessFactor # get and set (SubtractBackgroundCommand)

Property Value

Brightness factor for increasing or decreasing the brightness of the image. Valid values range from 0 - 400. If you pass 100 the brightness remains unchanged. Lower values darken the image while higher values lighten the image.

Example

Java

using Leadtools; 
using Leadtools.ImageProcessing; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void SubtractBackgroundCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Image4.Tif")); 
 
   // Prepare the command 
   SubtractBackgroundCommand command = new SubtractBackgroundCommand(); 
   command.RollingBall = 50; 
   command.BrightnessFactor = 100; 
   command.ShrinkingSize = SubtractBackgroundCommandType.DependOnRollingBallSize; 
   command.Flags = SubtractBackgroundCommandFlags.BackgroundIsDarker; 
   //Apply Subtract Background effect on the image. 
   command.Run(image); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
