Struct Encoder 

pub struct Encoder { /* private fields */ }

Ultra HDR encoder.

For production use without a bundled JPEG codec, use encode_ultrahdr directly.

The builder methods that require a JPEG codec (set_hdr_image, set_sdr_image, encode) are only available in tests where zenjpeg is a dev-dependency.

Implementations

impl Encoder

pub fn new() -> Self

Create a new encoder with default settings.

pub fn set_compressed_sdr(&mut self, jpeg: Vec<u8>) -> &mut Self

Set a pre-compressed SDR JPEG.

pub fn set_base_jpeg(&mut self, jpeg: Vec<u8>) -> &mut Self

Alias for set_compressed_sdr.

pub fn set_existing_gainmap_jpeg( &mut self, jpeg: Vec<u8>, metadata: GainMapMetadata, ) -> &mut Self

Set an existing gain map as raw JPEG bytes and metadata.

pub fn set_gainmap_jpeg( &mut self, jpeg: Vec<u8>, metadata: GainMapMetadata, ) -> &mut Self

Alias for set_existing_gainmap_jpeg.

pub fn set_quality(&mut self, base: u8, gainmap: u8) -> &mut Self

Set JPEG quality for base and gain map images.

pub fn set_gainmap_scale(&mut self, scale: u8) -> &mut Self

Set gain map downscale factor.

pub fn set_target_display_peak(&mut self, nits: f32) -> &mut Self

Set target display peak brightness in nits.

pub fn set_min_content_boost(&mut self, boost: f32) -> &mut Self

Set minimum content boost.

pub fn encode_from_jpegs(&self) -> Result<Vec<u8>>

Encode to Ultra HDR JPEG from pre-set JPEGs (production API).

impl Default for Encoder

fn default() -> Encoder
