Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void SliceCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
 
   // Prepare the command 
   SliceCommand cmd = new SliceCommand(); 
   cmd.FillColor = new RasterColor(0, 0, 0); 
   cmd.MaximumDeskewAngle = 40; 
   cmd.Flags = SliceCommandFlags.Bicubic | SliceCommandFlags.WithoutCut | SliceCommandFlags.DeskewImage; 
   cmd.Slice += new EventHandler<SliceCommandEventArgs>(SliceEventExample_S1); 
 
   // Apply the slice command on the image. 
   cmd.Run(image); 
 
   // Print out the deskew amount. 
   Console.WriteLine("Deskew Angle = {0}", cmd.DeskewAngle); 
 
} 
 
private void SliceEventExample_S1(object sender, SliceCommandEventArgs e) 
{ 
   // create a region around the slice 
   if (e.Image.HasRegion) 
      e.Image.AddRectangleToRegion(null, e.SliceRectangle, Leadtools.RasterRegionCombineMode.Xor); 
   else 
      e.Image.AddRectangleToRegion(null, e.SliceRectangle, Leadtools.RasterRegionCombineMode.Set); 
 
   // print out the deskew angle 
   Console.WriteLine("The rotation Amount is {0}", e.DeskewAngle); 
}
