Property Value

Handle to a windows region.

Remarks

When InvertedTextCommand returns, this property is updated with a single LEADTOOLS RasterRegion corresponding to all changes, only if InvertedTextCommandFlags.SingleRegion has been set in the Flags property and InvertedTextCommandFlags.LeadRegion has not been set. To use this property, set the InvertedTextCommandFlags.SingleRegion flag. Dispose of this region when the region is no longer needed.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void InvertedTextConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   InvertedTextCommand command = new InvertedTextCommand(InvertedTextCommandFlags.UseDpi, 5000, 500, 70, 95); 
   command.InvertedText += new EventHandler<InvertedTextCommandEventArgs>(InvertedTextEvent_S2); 
   command.Run(image); 
 
} 
 
private void InvertedTextEvent_S2(object sender, InvertedTextCommandEventArgs e) 
{ 
   MessageBox.Show("Size " + "( " + e.BoundingRectangle.Left + ", " + e.BoundingRectangle.Top + ") - " + "( " + e.BoundingRectangle.Right + ", " + e.BoundingRectangle.Bottom + ")" + 
      "\n Black Count " + e.BlackCount.ToString() + 
      "\n White Count " + e.WhiteCount.ToString()); 
   e.Status = RemoveStatus.Remove; 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
