Struct HdrImage 

pub struct HdrImage { /* private fields */ }

Tightly packed scene-linear RGBA16F pixels owned by the caller.

rgba16f contains row-major RGBA components as little-endian IEEE 754 binary16 words. Keeping the native eight-byte texel avoids expanding a 4K readback to twice its size on the CPU. Exposure, bloom, tone mapping, display-gamut conversion, transfer encoding and screen overlays are not baked into these scene-linear values.

Implementations

impl HdrImage

pub const fn width(&self) -> u32

Width in pixels.

pub const fn height(&self) -> u32

Height in pixels.

pub fn rgba16f(&self) -> &[u8]

Borrowed, tightly packed scene-linear RGBA16F pixels.

pub fn write_exr(&self, writer: impl Write) -> Result<(), RenderError>

Streams deterministic, uncompressed OpenEXR to a caller-owned sink.

Only one planar scanline is allocated and reused, so a 4K export does not duplicate the complete RGBA16F frame in host memory.

Errors

Returns RenderError::ImageEncoding for malformed pixels, layout overflow, or a sink write failure.
