SliceCommand Class

Summary

Extracts individual slices from a radiographic scanned film. This method is available in the Imaging and above toolkits.

Syntax

C++/CLI

Python

public class SliceCommand : RasterCommand

public ref class SliceCommand : public RasterCommand

class SliceCommand(RasterCommand):

Remarks

.This command is designed to extract the individual slices from radiographic scanned film. The image below shows an example of these radiographic images before and after applying the SliceCommand where we use the output data to draw a white line around each separate slice.

Before

After
This method supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This method does not support signed data images.
This command does not support 32-bit grayscale images.

Example

This event will draw a new region around the newly found slice.

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); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
