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.
| Class | Description |
|---|---|
| JPEGHuffmanTable | A class encapsulating a single JPEG Huffman table. |
| JPEGImageReadParam | This class adds the ability to set JPEG quantization and Huffman tables when using the built-in JPEG reader plug-in. |
| JPEGImageWriteParam | 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. |
| JPEGQTable | A class encapsulating a single JPEG quantization table. |
