JPEG Huffman encoder AC1
HCODE6 | Huffman code 6 8 least significant bits of the Huffman code. If the Huffman code is less than 8 bits long, the unused bits must be 0. |
HLEN6 | Huffman length 6 Number of bits in the Huffman code HCODE6 minus 1. |
HCODE7 | Huffman code 7 8 least significant bits of the Huffman code. If the Huffman code is less than 8 bits long, the unused bits must be 0. |
HLEN7 | Huffman length 7 Number of bits in the Huffman code HCODE7 minus 1. |
