SliceCommandEventArgs Constructor

Summary

Initializes a new SliceCommand with explicit parameters.

Syntax

C++/CLI

Python

public SliceCommandEventArgs( 
   RasterImage image, 
   RasterImage sliceImage, 
   LeadRect sliceRectangle, 
   int deskewAngle 
)

public: 
SliceCommandEventArgs(  
   RasterImage^ image, 
   RasterImage^ sliceImage, 
   LeadRect sliceRectangle, 
   int deskewAngle 
)

__init__(self,image,sliceImage,sliceRectangle,deskewAngle) # Overloaded constructor

Parameters

image
The affected images.

sliceImage
The sliced images. It is the programmer's responsibility to free this image, when it is no longer needed, this member is updated only if SliceCommandFlags.CutSlices flag is used, else it will be null.

sliceRectangle
The bounding rectangle of the extracted slice.

deskewAngle
Angle of deskewing. The amount of rotation is expressed in hundredths of degrees. For example, 500 means 5 degrees clockwise.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void SliceCommandEventArgsExample() 
{ 
   // 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(40, new RasterColor(0, 0, 0), SliceCommandFlags.Bicubic | SliceCommandFlags.CutSlices | SliceCommandFlags.DeskewImage); 
   cmd.Slice += new EventHandler<SliceCommandEventArgs>(SliceEventExample_S2); 
 
   // 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_S2(object sender, SliceCommandEventArgs e) 
{ 
   e.Image.AddPage(e.SliceImage); 
   e.Cancel = true; 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images"; 
}
