ResizeInterpolateCommand Class

Summary

Applies different kinds of algorithms on images to resize them into the desired size.

Syntax

Java

Objective-C

WinRT C#

C++

public class ResizeInterpolateCommand : RasterCommand

Public Class ResizeInterpolateCommand  
   Inherits Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand 
   Implements Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

public sealed class ResizeInterpolateCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

@interface LTResizeInterpolateCommand : LTRasterCommand

public class ResizeInterpolateCommand extends RasterCommand

function Leadtools.ImageProcessing.Core.ResizeInterpolateCommand()

public ref class ResizeInterpolateCommand : public Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

Remarks

This command keeps the same bitmap handle and resizes the bitmap that it references.
This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical Toolkits.
This command does not support 32-bit grayscale images.

Example

Run the ResizeCommand on an image.
