Justin Ruggles	c6698dfe7c	webpdec: Fix decoding of the huffman group indices. Per the specification, "The red and green components of a pixel define the meta Huffman code used in a particular block of the ARGB image."	11 years ago
Justin Ruggles	d085f80fa1	webp: add a special case for a huffman table with only 1 symbol The vlc reader cannot handle 0-bit huffman codes. For most situations WebP uses the "simple" huffman coding for this case, but that will only handle symbols up to 255. For the LZ77 distance codes, larger symbol values are needed, so it can happen in rare cases that a normal huffman table is used that only has a single symbol.	11 years ago
