Function render_element_with 

pub fn render_element_with<Msg>(
    el: Element<Msg>,
    theme: &Theme,
    size: (u32, u32),
    fonts: &mut Fonts,
) -> RgbaImage

Like render_element, but with caller-provided Fonts, so design languages can register Display/Serif faces (Fonts::register) and render through them. The requested size is clamped like render_element’s.

Panics

If no compute-capable GPU adapter exists or rendering fails.
