All Implemented Interfaces:

ImageResizer

public class MultistepSmoothImageResizer
extends FastImageResizer

An implementation of ImageResizer that focuses on generating good quality resized images. If the image is too large, it resizes it in two steps, first it uses FastImageResizer to resize to MultistepSmoothImageResizer.LOSSLESS_COMPRESSION_THRESHOLD times the target image, then it resizes this image using smooth transformations.
