Struct HeadlessImage 

pub struct HeadlessImage {
    pub width: u32,
    pub height: u32,
    pub rgba8: Vec<u8>,
    pub meta: HeadlessMeta,
}

The pixels of one headless render, plus the provenance of the GPU that produced them.

Fields

width: u32

Width in pixels, matching the HeadlessSpec that produced it.

height: u32

Height in pixels.

rgba8: Vec<u8>

Tightly packed RGBA8 rows — width * height * 4 bytes, no row padding, in the engine’s PREMULTIPLIED alpha convention (an erased pixel reads [0, 0, 0, 0]).

meta: HeadlessMeta

The GPU this image came from.

Implementations

impl HeadlessImage

pub fn pixel(&self, x: u32, y: u32) -> [u8; 4]

The RGBA bytes of pixel (x, y).

Panics

Panics when (x, y) is outside the image — an out-of-bounds probe in a pixel assertion is a broken test, not a runtime condition to handle.
