Examples of com.sun.image.codec.jpeg.JPEGQTable

com.sun.image.codec.jpeg.JPEGQTable
Class to encapsulate the JPEG quantization tables.
Note that the classes in the com.sun.image.codec.jpeg package are not part of the core Java APIs. They are a part of Sun's JDK and JRE distributions. Although other licensees may choose to distribute these classes, developers cannot depend on their availability in non-Sun implementations. We expect that equivalent functionality will eventually be available in a core API or standard extension.
