Expand description

Trait for size scaling relative to the viewport.

Required Methods§

Source

fn scale_viewport( self, scaling: Scale2D, viewport: Size<T>, original: Size<T>, clamp: Option<T>, ) -> Size<T>

Produce a Size<T> scaled with the input scaling options. The size will at minimum be 1x1, and at a maximum of the specified clamp value, or 16384x16384 if the clamp value is not specified.
