Struct OneBitSettings 

#[non_exhaustive]
pub struct OneBitSettings {
    pub dither: Dither,
    pub alpha_cut: u8,
    pub invert: bool,
}

A picture’s onebit import settings section (ADR-0057): how it is made one-bit. Every field may be left out: (onebit: ()) is the default, Atkinson with a cut at 128.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

dither: Dither

How its greys become black and white.

alpha_cut: u8

The alpha below which a pixel is see-through (0 for none).

invert: bool

Whether its brightness is turned over first, so black becomes white.
