package javax.imageio.plugins.jpeg
Classes supporting the built-in JPEG plug-in.

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 `ImageReadParam` and `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.
