ResizeInterpolateCommand Class

Summary

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

Syntax

Objective-C

C++/CLI

Java

Python

public class ResizeInterpolateCommand : RasterCommand

@interface LTResizeInterpolateCommand : LTRasterCommand

public class ResizeInterpolateCommand 
    extends RasterCommand

public ref class ResizeInterpolateCommand : public RasterCommand

class ResizeInterpolateCommand(RasterCommand):

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 ResizeInterpolateCommand on an image.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
 
public void ResizeCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   ResizeInterpolateCommand command = new ResizeInterpolateCommand(); 
 
   // Resize the bitmap into 50 pixels x 50 pixels using the Bilinear algorithm. 
   command.Width = 50; 
   command.Height = 50; 
   command.ResizeType = ResizeInterpolateCommandType.Bilinear; 
   command.Run(image); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";

    command.setResizeType(ResizeInterpolateCommandType.BILINEAR); 
    int change = command.run(image); 
    assertTrue(change != RasterImageChangedFlags.NONE); 
 
    codecs.save(image, combine(LEAD_VARS_IMAGES_DIR, "Result.jpg"), RasterImageFormat.JPEG, 24);
