Options for frame encoding.

Fields

use_modular: bool

Use modular mode (lossless).

effort: u8

Effort level (1-10, higher = better compression, slower).

use_ans: bool

Use ANS entropy coding instead of Huffman for modular.

use_tree_learning: bool

Use content-adaptive MA tree learning for modular encoding.

use_squeeze: bool

Use squeeze (Haar wavelet) transform for modular encoding.

enable_lz77: bool

Enable LZ77 compression on modular token streams.

lz77_method: Lz77Method

LZ77 method to use when enable_lz77 is true.

lossy_palette: bool

Use lossy delta palette for near-lossless modular encoding.

encoder_mode: EncoderMode

Encoder mode: Reference (match libjxl) or Experimental (own improvements).

profile: EffortProfile

Effort profile with all effort-derived parameters.

have_animation: bool

Whether this frame is part of an animation (enables duration field in header).

duration: u32

Duration of this frame in ticks (only used when have_animation is true).

is_last: bool

Whether this is the last frame in the image/animation.

crop: Option<FrameCrop>

Optional crop rectangle for this frame (None = full frame).

skip_rct: bool

Skip RCT even for 3-channel images (e.g., XYB channels already decorrelated).

Trait Implementations

impl Clone for FrameEncoderOptions

fn clone(&self) -> FrameEncoderOptions

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FrameEncoderOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FrameEncoderOptions

fn default() -> Self

Returns the “default value” for a type.
