Expand description

Coder parameters (makernote ImageProcessing tags 0x640..0x653).

Fields§

§extra_bits: u32

0x640: extra literal low bits per sample (value is shifted left by this).

§grad_shift: u32

0x641: log2 of the gradient threshold of the predictor.

§edge_pred: i32

0x642: prediction used outside the image (first rows/columns).

§low_bits: u32

0x643: literal low bits coded before the adaptive part (0, 1 or 2).

§smooth_shift: u32

0x644: smoothing shift of the residual accumulator (15 disables it).

§small_shift: u32

0x645: codes up to 1 << small_shift count as “small” for the run counter.

§run_switch: i32

0x646: run length of small codes that switches to the fine width model.

§run_offset: i32

0x647/0x648: width model after a run (offset, magnitude threshold).

§run_threshold: i32§base_offset: i32

0x649/0x650: default width model (offset, magnitude threshold).

§base_threshold: i32§max_wbits: i32

0x651: maximum adaptive width.

§max_high: u32

0x652: unary escape length.

§header_len: u32

0x653: length of the big-endian stream header (value 1) preceding two zero bytes.
