public class AlignImagesCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration

Public Class AlignImagesCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As AlignImagesCommand

public sealed class AlignImagesCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTAlignImagesCommand : LTRasterCommand

public class AlignImagesCommand extends RasterCommand

function Leadtools.ImageProcessing.Core.AlignImagesCommand()

public ref class AlignImagesCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

The two images should have the same depth (i.e. Bits Per Pixel); otherwise, this class will throw an Invalid Parameter exception.
It is best to choose points that are far apart from each other.
The transformation performed depends upon the number of pairs of corresponding points given. As many as four pairs can be given.
Set the reference image using the Run method and set the template image using the TemplateImage property.
Set the template image before calling the Run method; otherwise, an Invalid Parameter exception will be thrown.
This function supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 1-2 and 16-bit grayscale and 48- and 64-bit color images is available only in the Document and Medical Imaging toolkits.
This command supports signed/unsigned images.
