public class Brightness
extends LookupTableOperation

Adjusts the brightness of an image. The amount of adjustment is given to the constructor as a percentage value between -100 and 100. -100 will make the resulting image black, 0 will leave it unchanged, 100 will make it white.

Usage example

This code snippet will increase image's brightness by 30 percent.
 Brightness brightness = new Brightness();
 brightness.setInputImage(image);
 brightness.setBrightness(30);
 brightness.process();
 PixelImage adjustedImage = brightness.getOutputImage();
