Gets or sets a value that indicates the threshold for showing the image variances.

Syntax

Objective-C

@property (nonatomic, assign) NSUInteger threshold;

public: 
property int Threshold { 
   int get(); 
   void set (    int );

Threshold # get and set (SelectDataCommand)

Property Value

Value that indicates the threshold for showing the image variances. If the mask value is greater or equal to the threshold value then the pixel will be colored using Color. See Combine for more details. This property accepts only positive values.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
 
public void SelectDataCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg")); 
 
   // Prepare the command 
   SelectDataCommand command = new SelectDataCommand(); 
   command.Color = new RasterColor(233, 10, 77); 
   command.Combine = true; 
   command.SourceLowBit = 2; 
   command.SourceHighBit = 6; 
   command.Threshold = 25; 
 
   command.Run(image); 
   codecs.Save(command.DestinationImage, Path.Combine(LEAD_VARS.ImagesDir, "SelectDataResult.Bmp"), RasterImageFormat.Bmp, 24); 
 
}
