Class ProgressiveBilinearResizer

java.lang.Object
  net.coobird.thumbnailator.resizers.AbstractResizer
      net.coobird.thumbnailator.resizers.ProgressiveBilinearResizer

All Implemented Interfaces:

Resizer

public class ProgressiveBilinearResizer
extends AbstractResizer

A Resizer which performs resizing operations by using progressive bilinear scaling.

The resizing technique used in this class is based on the technique discussed in Chapter 4: Images of Filthy Rich Clients by Chet Haase and Romain Guy.

The actual implemenation of the technique is independent of the code which is provided in the book.
