Class DynamicColorReducer

java.lang.Object
  com.davisor.graphics.ColorReducer
      com.davisor.graphics.DynamicColorReducer

All Implemented Interfaces:

java.awt.image.BufferedImageOp

Direct Known Subclasses:

OctreeColorReducer

public abstract class DynamicColorReducer

extends ColorReducer

DynamicColorReducer implements an abstract base class for dynamic color reducers that can approximate given color sets with smaller ones.

DynamicColorReducer offers a common interface for different color quantization adaptation methods. It also provides a generic image scanner that can fill the reducer with colors taken from the image.

Since:

JDK1.3
