public class Rescale

extends Lens

Rescale lens. As described in the "Programmer’s Guide to the Java 2D™ API": "Rescaling can increase or decrease the intensity of all points. Rescaling can be used to increase the dynamic range of an otherwise neutral image, bringing out detail in a region that appears neutral or flat."
