Examples of DataBufferByte

ae.java.awt.image.DataBufferByte
This class extends DataBuffer and stores data internally as bytes. Values stored in the byte array(s) of this DataBuffer are treated as unsigned values.
Note that some implementations may function more efficiently if they can maintain control over how the data for an image is stored. For example, optimizations such as caching an image in video memory require that the implementation track all modifications to that data. Other implementations may operate better if they can store the data in locations other than a Java array. To maintain optimum compatibility with various optimizations it is best to avoid constructors and methods which expose the underlying storage as a Java array, as noted below in the documentation for those methods.
