Struct Image 

pub struct Image { /* private fields */ }

A tree-compatible image widget that blits a PNG file or bytes onto the canvas.

Wraps crate::ImageWidget as a Widget so it can be used as a child of Column, Row, Stack, etc.

Implementations

impl Image

pub fn file(path: impl Into<PathBuf>) -> Self

Create an image from a file path.

pub fn asset(name: impl AssetRef) -> Self

pub fn height(self, h: f32) -> Self

pub fn alt(self, alt: impl Into<String>) -> Self
