Class PerspectiveTransform
java.lang.Object
com.google.zxing.common.PerspectiveTransform
This class implements a perspective transform in two dimensions. Given four source and four destination points, it will compute the transformation implied between them. The code is based directly upon section 3.4.2 of George Wolberg's "Digital Image Warping"; see pages 54-56.
