Trait Renderer

pub trait Renderer: Renderer {
    type Handle: Clone;

    // Required methods
    fn measure_image(&self, handle: &Self::Handle) -> Size<u32>;
    fn draw_image(
        &mut self,
        handle: Self::Handle,

        rotation: Radians,
        opacity: f32,
        border_radius: [f32; 4],
    );
}

A Renderer that can render raster graphics.

Required Associated Types

type Handle: Clone

The image Handle to be displayed. Iced exposes its own default implementation of a Handle

Required Methods

fn measure_image(&self, handle: &Self::Handle) -> Size<u32>

Returns the dimensions of an image for the given Handle.

fn draw_image( &mut self, handle: Self::Handle, filter_method: FilterMethod, bounds: Rectangle, rotation: Radians, opacity: f32, border_radius: [f32; 4], )

Draws an image with the given Handle and inside the provided bounds.

Object Safety

This trait is not object safe.
