public DotRemoveCommand( 
   int flags,  
   int minimumDotWidth,

Parameters

flags
Flag that determines the behavior of the dot removal process.

minimumDotWidth
The minimum width of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

minimumDotHeight
The minimum height of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

maximumDotWidth
The maximum width of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

maximumDotHeight
The maximum height of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

Example

Run the DotRemoveCommand on an image.

C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void DotRemoveConstructorExample() 
{ 
   // 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(DotRemoveCommandFlags.UseSize | DotRemoveCommandFlags.SingleRegion, 1, 1, 10, 10); 
   command.DotRemove += new EventHandler<DotRemoveCommandEventArgs>(DotRemoveEvent_S2); 
   command.Run(image); 
 
} 
 
private void DotRemoveEvent_S2(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"; 
}
