ResizeInterpolateCommand Class

Summary

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

Syntax
C#
VB
Java
Objective-C
C++
public class ResizeInterpolateCommand : RasterCommand 
Public Class ResizeInterpolateCommand  
   Inherits RasterCommand 
@interface LTResizeInterpolateCommand : LTRasterCommand 
public class ResizeInterpolateCommand extends RasterCommand 
public ref class ResizeInterpolateCommand : public 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 ResizeCommand on an image.
