This package contains some support classes for the built-in JPEG reader and
writer plug-ins. Classes are provided for representing quantization and
Huffman tables, and extensions of
ImageWriteParam are provided to supply tables during the reading and
writing process. For more information about the operation of the built-in
JPEG plug-ins, see the
JPEG metadata format
specification and usage notes.
