Struct YCbCrPlanarEncoder 

pub struct YCbCrPlanarEncoder { /* private fields */ }

Encoder for planar f32 YCbCr input.

Use when you have pre-converted YCbCr from video decoders, etc. Skips RGB->YCbCr conversion entirely.

Only valid with ColorMode::YCbCr. XYB mode requires RGB input.

Implementations

impl YCbCrPlanarEncoder

pub fn push( &mut self, planes: &YCbCrPlanes<'_>, rows: usize, stop: impl Stop, ) -> Result<()>

Push full-resolution planes. Encoder subsamples chroma as needed.

• planes: Y, Cb, Cr plane data with per-plane strides
• rows: Number of luma rows to push
• stop: Cancellation token

pub fn push_subsampled( &mut self, planes: &YCbCrPlanes<'_>, y_rows: usize, stop: impl Stop, ) -> Result<()>

Push with pre-subsampled chroma.

Cb/Cr are already at target chroma resolution. y_rows is luma row count; chroma rows derived from ChromaSubsampling.

pub fn width(&self) -> u32

Get image width.

pub fn height(&self) -> u32

Get image height.

pub fn rows_pushed(&self) -> u32

Get number of rows pushed so far.

pub fn rows_remaining(&self) -> u32

Get number of rows remaining.

pub fn finish(self) -> Result<Vec<u8>>

Finish encoding, return JPEG bytes.

pub fn finish_to<W: Write>(self, output: W) -> Result<W>

Finish encoding to Write destination.

pub fn finish_to_vec(self, output: &mut Vec<u8>) -> Result<()>

Finish encoding, appending JPEG bytes to an existing Vec.

Useful for no_std environments or buffer reuse.
