The module jpeg provides access to the jpeg compressor and decompressor written by the Independent JPEG Group (IJG). JPEG is a standard for compressing pictures; it is defined in ISO 10918. For details on JPEG or the Independent JPEG Group software refer to the JPEG standard or the documentation provided with the software.
A portable interface to JPEG image files is available with the Python Imaging Library (PIL) by Fredrik Lundh. Information on PIL is available at http://www.pythonware.com/products/pil/.
The jpeg module defines an exception and some functions.

| Option | Effect | 
|---|---|
| 'forcegray' | Force output to be grayscale, even if input is RGB. | 
| 'quality' | Set the quality of the compressed image to a value between 0and100(default is75).  This only affects
    compression. | 
| 'optimize' | Perform Huffman table optimization. Takes longer, but results in smaller compressed image. This only affects compression. | 
| 'smooth' | Perform inter-block smoothing on uncompressed image. Only useful for low-quality images. This only affects decompression. |
