ImageRegion Property

Summary

This property is updated with a shallow copy of the image that also has a region that contains the removed dots.

Syntax

Objective-C

C++/CLI

Java

Python

public RasterImage ImageRegion { get; }

@property (nonatomic, strong, readonly, nullable) LTRasterImage *imageRegion;

public RasterImage getImageRegion();

public: 
property RasterImage^ ImageRegion { 
   RasterImage^ get(); 
}

ImageRegion # get  (DotRemoveCommand)

Property Value

A shallow copy of the image that also has a region that contains the removed dots.

Remarks

If DotRemoveCommandFlags.SingleRegion| DotRemoveCommandFlags.LeadRegion has been set in Flags, then when DotRemoveCommand returns, this property is updated with a shallow copy of the image that also has a region that contains the removed dots. So set Flags to (DotRemoveCommandFlags.SingleRegion| DotRemoveCommandFlags.LeadRegion). It is the programmer's responsibility to dispose of the region when it is no longer needed.

Example

Run the DotRemoveCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void ImageRegionPropertyExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   DotRemoveCommand command = new DotRemoveCommand(); 
   command.DotRemove += new EventHandler<DotRemoveCommandEventArgs>(DotRemoveEvent_S3); 
   command.Flags = DotRemoveCommandFlags.UseSize | DotRemoveCommandFlags.SingleRegion | DotRemoveCommandFlags.LeadRegion; 
   command.MaximumDotHeight = 10; 
   command.MaximumDotWidth = 10; 
   command.MinimumDotHeight = 1; 
   command.MinimumDotWidth = 1; 
 
   command.Run(image); 
 
} 
 
private void DotRemoveEvent_S3(object sender, DotRemoveCommandEventArgs e) 
{ 
   // Do not remove the speck if it contains any white pixels 
   if (e.WhiteCount > 0) 
   { 
      e.Status = RemoveStatus.NoRemove; 
   } 
   else 
   { 
      e.Status = RemoveStatus.Remove; 
   } 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
