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."

  Description copied from class: `Lens`
  Effect: arbitrary drawing on top. Can even traverse tree for special effects (that don't compose with other lenses). Warning: this type of effects don't compose as well with other lenses.

  Overrides:
    `paintAfter` in class `Lens`
  Returns:
    false so it composes with other lenses
