Struct ImageResource 

pub struct ImageResource {
    pub key: ImageKey,
    pub width: u32,
    pub height: u32,
    pub data: Vec<u8>,
}

A decoded image referenced by one or more DrawImage / DrawRepeatingImage items. Like FontResource, the pixels travel in the paint output’s image side-table (PaintList::images) rather than inline on each item, so an image used by several items ships its bytes once. The renderer interns each ImageResource into its atlas and maps key → its internal image id; ImageItem::image_key then resolves through that map.

Pixels are RGBA8, row-major, tightly packed — data.len() == width * height * 4. The producer is responsible for decoding (PNG / JPEG / data-URI / etc.) into this shape; the renderer just uploads the bytes.

Fields

key: ImageKey

The key ImageItem::image_key references.

width: u32

Image width in pixels.

height: u32

Image height in pixels.

data: Vec<u8>

Decoded RGBA8 bytes (width * height * 4).
