Class ImageRotationSet

java.lang.Object
  com.partnersoft.gui.ImageRotationSet

public class ImageRotationSet
extends java.lang.Object

This caches and manages various quantum rotations of an image. These are generated only when needed, then saved for future use. Rotations are numbered; there are 16 possible, counted from due east (zero degrees) and proceeding counter-clockwise. They are store as ImageRotation objects; these manage the offsets, true width and height, centering data, etc.
