Class Bitmap

java.lang.Object
fr.olleroy.ImageModifier.components.Bitmap
public class Bitmap extends Object
Bitmap class stores pixels and basic information about the image. Bitmap looks like a BufferedImage but is smaller in memory. BufferedImage could be more efficient to open files faster -> could upgrade to it.
