XForm Property

Summary

Gets or sets a RasterRegionXForm object used to translate between display coordinates and image coordinates.

Syntax

C++/CLI

Python

public RasterRegionXForm XForm { get; set; }

public: 
property RasterRegionXForm^ XForm { 
   RasterRegionXForm^ get(); 
   void set (    RasterRegionXForm^ ); 
}

XForm # get and set (RegionContourPointsCommand)

Property Value

RasterRegionXForm object used to translate between display coordinates and image coordinates. If you specify null in this property, 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";
