Struct V8Params 

pub struct V8Params {
    pub gamma_points: [u32; 6],
    pub gamma_slopes: [u32; 6],
    pub clip: u32,
    pub initial: [u16; 4],
    pub codes: Vec<(u8, u16)>,
    pub shift_down: Vec<u8>,
}

Format-8 parameters (RW2 tags 0x39–0x48).

Fields

gamma_points: [u32; 6]

Gamma curve: 6 (point, slope) pairs (tags 0x3A and 0x39).

gamma_slopes: [u32; 6]

clip: u32

Clip value (tag 0x3B).

initial: [u16; 4]

Initial predictions for the 2×2 block positions TL, TR, BL, BR (tags 0x3C–0x3F).

codes: Vec<(u8, u16)>

Huffman codes: (code length, code) per symbol (tag 0x40); the symbol index is the difference bit length.

shift_down: Vec<u8>

Per-symbol “shift down” (tag 0x41); zero in all known files.
