The Package contains the main classes of the Day Graphics Engine. This framework consists of one basic class : The Layer class is the functional basis onto which the whole Graphics Engine is built. Though the classes implementing the java.awt.image.BufferedImageOp interface take java.awt.image.BufferedImage as parameters, they are also heavily used by the methods provided by the Layer class.

The rest of the classes in the Package contain more functionality of the Graphics Engine for direct use with the Layer class.
