Struct ImageData 

pub struct ImageData { /* private fields */ }

Decoded pixels: RGBA8, straight (not premultiplied) alpha, sRGB, row-major. Cloning is cheap; the renderer caches the GPU texture by id.

Implementations

impl ImageData

pub fn from_rgba8( width: u32, height: u32, pixels: impl Into<Arc<[u8]>>, ) -> Option<ImageData>

Wraps RGBA8 pixels. Returns None when the buffer does not match the size.

pub fn from_fn( width: u32, height: u32, f: impl Fn(u32, u32) -> Color, ) -> Option<ImageData>

Builds an image by evaluating f(x, y) for every pixel (procedural art, tests).

pub fn id(&self) -> u64

Stable identity used as the GPU cache key.

pub fn width(&self) -> u32

Width in pixels.

pub fn height(&self) -> u32

Height in pixels.

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

RGBA8 pixel bytes, row-major, width * height * 4 long.

pub fn aspect_ratio(&self) -> f32

Width divided by height.
