Struct Image

pub struct Image { /* private fields */ }

An image widget. Pretty self-explanatory.

See the image example for how to use it in practice.

Theming

The widget itself only draws the underlying image, so theming is useless.

impl Image

pub fn new(image: impl Into<MaybeSignal<ImageData>>) -> Self

Create an image widget from the given ImageData.

pub fn with_image(self, image: impl Into<MaybeSignal<ImageData>>) -> Self
