RegionContourPointsCommand Class

Summary

Gets the contour coordinates of a region.

Syntax

C++/CLI

Python

public class RegionContourPointsCommand : RasterCommand

public ref class RegionContourPointsCommand : public RasterCommand

class RegionContourPointsCommand(RasterCommand):

Remarks

This command works only on images having a region. If the image does not have a region the command returns the error: Not Initialized.
This command 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.

Example

Run the RegionContourPointsCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void RegionContourPointsCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
 
   // Prepare the command 
   LeadRect rcRect = new LeadRect(image.Width / 3, image.Height / 3, image.Width * 2 / 3, image.Height * 2 / 3); 
   image.AddEllipseToRegion(null, rcRect, RasterRegionCombineMode.Set); 
   RegionContourPointsCommand command = new RegionContourPointsCommand(null); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
