Struct FrameEncoder 

pub struct FrameEncoder { /* private fields */ }

Encodes a single frame.

Implementations

impl FrameEncoder

pub fn new(width: usize, height: usize, options: FrameEncoderOptions) -> Self

Creates a new frame encoder.

pub fn new_with_extra_channels( width: usize, height: usize, options: FrameEncoderOptions, num_extra_channels: usize, ) -> Self

Creates a new frame encoder with extra channel support.

pub fn encode_modular( &self, image: &ModularImage, _color_encoding: &ColorEncoding, writer: &mut BitWriter, ) -> Result<()>

Encodes a modular image into a frame.

pub fn num_groups(&self) -> usize

Returns the number of groups in this frame.

pub fn num_groups_x(&self) -> usize

Returns the number of groups in X direction.

pub fn num_groups_y(&self) -> usize

Returns the number of groups in Y direction.

pub fn num_lf_groups(&self) -> usize

Returns the number of LF groups (DC groups). LF groups are 8x the size of regular groups (2048x2048 pixels).

pub fn num_toc_entries(&self, num_passes: usize) -> usize

Returns the number of TOC entries for this frame. Single group: 1 entry Multi-group: 2 + num_lf_groups + num_groups * num_passes

pub fn group_bounds(&self, group_idx: usize) -> (usize, usize, usize, usize)

Get the pixel bounds for a group. Returns (x_start, y_start, x_end, y_end).
