Examples of JPEGQTable

ae.javax.imageio.plugins.jpeg.JPEGQTable
A class encapsulating a single JPEG quantization table. The elements appear in natural order (as opposed to zig-zag order). Static variables are provided for the "standard" tables taken from Annex K of the JPEG specification, as well as the default tables conventionally used for visually lossless encoding.
For more information about the operation of the standard JPEG plug-in, see the JPEG metadata format specification and usage notes
com.google.code.appengine.imageio.plugins.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.
