Syntax

Objective-C

C++/CLI

Java

Python

public LeadPoint[] MappingPoints { get; set; }

@property (nonatomic, strong, nullable) NSArray<NSValue *> *mappingPoints; //LeadPoint

public LeadPoint[ getMappingPoints(); 
public void setMappingPoints( 
   LeadPoint[] leadPoint[ 
);

public: 
property array<LeadPoint>^ MappingPoints { 
   array<LeadPoint>^ get(); 
   void set (    array<LeadPoint>^ ); 
}

Property Value

Array of points that map each point in the InputPoints list to its output location.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void ManualPerspectiveDeskewCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "PerspectiveDeskew.jpg")); 
 
   LeadPoint[] PolyPoints = new LeadPoint[4]; 
   LeadPoint[] MappingPoints = new LeadPoint[4]; 
 
   //The four corners of the polygon 
   PolyPoints[0] = new LeadPoint(131, 193); 
   PolyPoints[1] = new LeadPoint(456, 151); 
   PolyPoints[2] = new LeadPoint(535, 282); 
   PolyPoints[3] = new LeadPoint(124, 354); 
 
   //Prepare the command 
   ManualPerspectiveDeskewCommand command = new ManualPerspectiveDeskewCommand(); 
 
   command.InPoints = PolyPoints; 
 
   MappingPoints[0] = new LeadPoint(0, 0); 
   MappingPoints[1] = new LeadPoint(610, 0); 
   MappingPoints[2] = new LeadPoint(610, 421); 
   MappingPoints[3] = new LeadPoint(0, 421); 
 
   command.MappingPoints = MappingPoints; 
 
   //Apply  
   command.Run(image); 
 
   codecs.Save(command.OutputImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), image.OriginalFormat, image.BitsPerPixel); 
} 
 
static class LEAD_VARS
