Struct Pictures 

pub struct Pictures { /* private fields */ }

What a component showing a picture reads: the store its bytes load through (which caches a decoded picture by its address), and what a window’s pictures are.

Implementations

impl Pictures

pub fn new(store: ImageStore) -> Pictures

The pictures this window reads, loaded by store.

pub fn window() -> Pictures

The window’s pictures: loaded through the store the toolkit builds for the window (the one its host serves), with content addresses read from the process’s content store.

pub fn store(&self) -> &ImageStore

The store it loads through, for a component that shows more than one picture.

pub fn get(&self, picture: &PictureSource) -> Option<ImageData>

The decoded picture at picture’s address, once its bytes are here: None while it loads (or when it names nothing, or failed to load). Asking starts the load. The store already caches a decoded picture by its address, so a picture still loading is asked for again each frame without a second cache here.

pub fn failed(&self, picture: &PictureSource) -> bool

Whether the picture at picture’s address has failed to load: its bytes are not here, or do not decode.
