Enum ScaleMode 

pub enum ScaleMode {
    Integer,
    Fit,
    Stretch,
}

How the virtual-resolution canvas is scaled onto the window. See GraphicsConfig::virtual_resolution.

Variants

Integer

Scale by the largest whole number that fits, so every canvas pixel becomes an equal square of window pixels; the rest of the window is border. Falls back to Fit when the window is smaller than the canvas.

Fit

Scale as large as fits while keeping the aspect ratio, by a fractional factor if need be (e.g. 800 × 600 on a 1080p screen). Canvas pixels then differ in size by one window pixel; ScaleFilter::Linear or a post-process filter hides that.

Stretch

Fill the whole window, distorting the aspect ratio.
