Struct ImageData 

pub struct ImageData { /* private fields */ }

An image’s pixels: 8-bit RGBA, sRGB, row by row from the top-left corner (width * height * 4 bytes). Immutable once built.

Implementations

impl ImageData

pub fn from_rgba(width: u32, height: u32, rgba: Vec<u8>) -> ImageData

Builds an image from raw RGBA pixels. Panics if the length is not width * height * 4.

pub fn into_handle(self) -> Arc<ImageData>

Wraps the image in a shared handle (cheap to clone, stable for caching).

pub fn id(&self) -> u64

Unique, stable identity (the GPU cache key).

pub fn width(&self) -> u32

Width in pixels.

pub fn height(&self) -> u32

Height in pixels.

pub fn size(&self) -> Size

Size in pixels, as a Size.

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

The RGBA bytes (sRGB), row by row.

Trait Implementations

impl Debug for ImageData

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for ImageData

impl PartialEq for ImageData

Two images are “equal” when they share the same identity — the same resource — without comparing pixels. That keeps cache lookups and scene equality cheap.

fn eq(&self, other: &ImageData) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
