Property Value

Maximum length of a break or a hole in a line. This can be used to remove dotted lines, dashed lines, or lines that have breaks due to scanning. If LineRemoveCommandFlags.UseDpi is set in the Flags property, units are in thousandths of an inch, otherwise units are in pixels. This property is valid only if LineRemoveCommandFlags.UseDpi is set in the Flags property.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void LineRemoveCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   LineRemoveCommand command = new LineRemoveCommand(); 
   command.LineRemove += new EventHandler<LineRemoveCommandEventArgs>(LineRemoveEvent_S1); 
   command.Type = LineRemoveCommandType.Horizontal; 
   command.Flags = LineRemoveCommandFlags.UseGap; 
   command.GapLength = 2; 
   command.MaximumLineWidth = 5; 
   command.MinimumLineLength = 200; 
   command.MaximumWallPercent = 10; 
   command.Wall = 7; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "CleanAfterLineRemoveCommand.tif"), RasterImageFormat.Tif, 0); 
   codecs.Dispose(); 
   image.Dispose(); 
} 
 
private void LineRemoveEvent_S1(object sender, LineRemoveCommandEventArgs e) 
{ 
      
   Debug.WriteLine("Row Col " + "( " + e.StartRow.ToString() + ", " + e.StartColumn + " )" + 
      "\n Length " + e.Length.ToString()); 
   e.Status = RemoveStatus.Remove; 
}
