Enum Fit

Source

pub enum Fit {
    Stretch,
    Letterbox {
        pad: [u8; 4],
    },
}

Expand description

How a source is fit into the requested destination shape.

Variants§

§

Stretch

Stretch the source (or source crop) to fill the whole destination.

§

Letterbox

Keep the source aspect ratio and pad the rest of the destination with the RGBA pixel pad (e.g. [114, 114, 114, 255] for YOLO-style preprocessing). Where the image sits is a LetterboxPlacement.

Fields

§pad: [u8; 4]

The RGBA pad pixel.
