Enum Encoding 

pub enum Encoding {
    Png,
    Jpeg {
        quality: u8,
        background: Color,
    },
    WebpLossless,
}

Encoding is the file encode writes, with its format’s settings.

Variants

Png

Png is an RGBA PNG, transparency kept.

Jpeg

Jpeg is a JPEG at quality, from 1 to 100, laid over background, since a JPEG holds no transparency; the background’s own alpha is ignored.

Fields

quality: u8

quality trades size for detail, from 1 to 100.

background: Color

background shows through where the pixels are transparent.

WebpLossless

WebpLossless is a lossless WebP, transparency kept.
