Enum ColorMode 

pub enum ColorMode {
    Normal,
    Gray,
    Alpha,
    Forced(ColorScheme),
}

The four colour modes. Three are reachable without any caller asking: Alpha from an alpha-type soft mask and from an uncoloured tiling pattern, Gray from a grayscale render, Forced from a colour scheme.

Variants

Normal

Colours pass through unchanged.

Gray

Every path and text colour collapses to its NTSC gray.

Alpha

Drawing writes alpha as gray: the mode a soft mask’s alpha group and an uncoloured tile render in.

Forced(ColorScheme)

Path and text colours are replaced wholesale; images, shadings and forms keep their own and are not gray-translated either.
