removed from the free JPEG software. (Since arithmetic coding provides only a marginal

gain over the unpatented Huffman mode, it is unlikely that very many implementations

will support it.) So far as we are aware, there are no patent restrictions on the remaining

code.

The IJG distribution formerly included code to read and write GIF files. To avoid

entanglement with the Unisys LZW patent, GIF reading support has been removed

altogether, and the GIF writer has been simplified to produce "uncompressed GIFs". This

technique does not use the LZW algorithm; the resulting GIF files are larger than usual, but

are readable by all standard GIF decoders.
