A class encapsulating a single JPEG Huffman table.
This class adds the ability to set JPEG quantization and Huffman tables when using the built-in JPEG reader plug-in.
This class adds the ability to set JPEG quantization and Huffman tables when using the built-in JPEG writer plug-in, and to request that optimized Huffman tables be computed for an image.
A class encapsulating a single JPEG quantization table.
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
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.
