Module huffman 

Huffman coding tables for JPEG entropy decoding and encoding.

Structs

HuffmanDecodeTable

Huffman decode table with two-level lookup.

HuffmanEncodeTable

Huffman encode table: maps symbol → (code_bits, code_length).

Functions

encode_value

Encode a signed value into JPEG “additional bits” representation. Returns (magnitude_bits, category/size).

extend_sign

Extend a signed value from its JPEG “additional bits” representation.
