DeskewAngle Property

Summary

Gets the variable that will be updated with the amount that the command rotates the sliced image. The amount of rotation is expressed in hundredths of degrees. For example, 500 means 5 degrees clockwise. This property is updated only if SliceCommandFlags.DeskewImage is selected in the Flags property.

Syntax

C++/CLI

Python

public int DeskewAngle { get; }

public: 
property int DeskewAngle { 
   int get(); 
}

DeskewAngle # get  (SliceCommand)

Property Value

A variable that will be updated with the amount that the command rotates the sliced image. The amount of rotation is expressed in hundredths of degrees. For example, 500 means 5 degrees clockwise. This property is updated only if SliceCommandFlags.DeskewImage is selected in the Flags property.

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); 
}
