JPEG Huffman encoder AC1
HCODE4 | Huffman code 4 8 least significant bits of the Huffman code. If the Huffman code is less than 8 bits long, the unused bits must be 0. |
HLEN4 | Huffman length 4 Number of bits in the Huffman code HCODE4 minus 1. |
HCODE5 | Huffman code 5 8 least significant bits of the Huffman code. If the Huffman code is less than 8 bits long, the unused bits must be 0. |
HLEN5 | Huffman length 5 Number of bits in the Huffman code HCODE5 minus 1. |
