Struct Image 

pub struct Image {
    pub width: u32,
    pub height: u32,
    pub pixels: Vec<u8>,
}

Mapped, tightly packed RGBA8 image owned by the caller.

Fields

width: u32

Width in pixels.

height: u32

Height in pixels.

pixels: Vec<u8>

Row-major RGBA8 pixels with no row padding.

Implementations

impl Image

pub fn png_bytes(&self) -> Result<Vec<u8>, RenderError>

Encodes the already-tonemapped image as a deterministic RGBA PNG.

The engine performs scene-linear HDR lighting, exposure, display grading and sRGB conversion before the readback. This method therefore serializes publication pixels without applying a second colour curve. No filesystem or application state is touched.

Errors

Returns RenderError::ImageEncoding if the pixel buffer is malformed or the PNG encoder rejects the stream.

pub fn write_png(&self, output: impl Write) -> Result<(), RenderError>

Streams deterministic RGBA PNG bytes into a caller-owned writer.

Errors

Returns RenderError::ImageEncoding for malformed pixels or an encoder/writer failure.
