Class DownscaleQuality

java.lang.Object

org.xhtmlrenderer.util.DownscaleQuality

public class DownscaleQuality
extends Object

Simple enumerated constants for downscaling (scaling to smaller image size)--since we have various options for what algorithm to use. Not general-purpose, applies only to methods used in ImageUtil. Types constants can be looked up using forString(String, DownscaleQuality) and the corresponding string for the quality
