RegionContourPointsCommand Constructor(RasterRegionXForm)

Summary

Initializes a new RegionContourPointsCommand class object with explicit parameters.

Syntax

C++/CLI

Python

public RegionContourPointsCommand( 
   RasterRegionXForm xForm 
)

public: 
RegionContourPointsCommand(  
   RasterRegionXForm^ xForm 
)

__init__(self,xForm) # Overloaded constructor

Parameters

xForm
RasterRegionXForm object that contains information used to translate between display coordinates and image coordinates. If you specify null in this parameter, the scalar value defaults to 1, the offsets default to 0, and the view perspective defaults to the image's view perspective.

Example

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); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
