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.

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"; 
}
