Syntax

C++/CLI

Python

public PerspectiveCommand( 
   LeadPoint[] cornerPoints, 
   RasterColor fillColor, 
   PerspectiveCommandType type 
)

public: 
PerspectiveCommand(  
   array<LeadPoint>^ cornerPoints, 
   RasterColor fillColor, 
   PerspectiveCommandType type 
)

__init__(self,cornerPoints,fillColor,type) # Overloaded constructor

Parameters

cornerPoints
Array of Leadtools.LeadPoint that determines the new locations of image corners.

fillColor
Background color

type
The type of background.

Example

Run the PerspectiveCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void PerspectiveConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample1.cmp")); 
 
   // Prepare the command 
   LeadPoint[] cornerPoints = new LeadPoint[4]; 
   cornerPoints[0].X = image.Width * 3 / 9; 
   cornerPoints[0].Y = image.Height * 1 / 12; 
   cornerPoints[1].X = image.Width * 3 / 4; 
   cornerPoints[1].Y = image.Height * 2 / 12; 
   cornerPoints[2].X = image.Width * 2 / 10; 
   cornerPoints[2].Y = image.Height * 8 / 10; 
   cornerPoints[3].X = image.Width * 10 / 11; 
   cornerPoints[3].Y = image.Height * 7 / 10; 
   PerspectiveCommand command = new PerspectiveCommand(cornerPoints, 
      new RasterColor(255, 0, 0), 
      PerspectiveCommandType.Image); 
   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";
