Struct Image 

pub struct Image {
    pub id: Option<NodeId>,
    pub request: ImageRequest,
    pub width: Option<f32>,
    pub height: Option<f32>,
    pub fit: ImageFit,
    pub alignment: ImageAlignment,
}

Displays an image from an asset, file, network URL, memory buffer, or inline SVG.

Image is declarative: it describes the image source and presentation. The active shell is responsible for loading, decoding, caching, and repainting when the image becomes available.

Fields

id: Option<NodeId>

Explicit node identity.

request: ImageRequest

Typed image request consumed by the shell image pipeline.

width: Option<f32>

Fixed width in layout points.

height: Option<f32>

Fixed height in layout points.

fit: ImageFit

How the image is scaled to fit its layout box.

alignment: ImageAlignment

How fitted image content is positioned inside its layout box.
