Property Value

Height of a wall. Walls are slices of a line that are too wide to be considered part of the line. Examples of walls include a character that a line passes through or a perpendicular line. If the image contains lines that pass through characters, set Wall to be equal to or a little larger than MaximumLineWidth. If LineRemoveCommandFlags.UseDpi is set in the Flags property, units are in thousandths of an inch, otherwise units are in pixels.

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; 
}

{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
