Struct Gray2

Source
pub struct Gray2(/* private fields */);
Expand description

2 bit grayscale color.

Implementations§

Source§

impl Gray2

Source

pub const fn new(luma: u8) -> Self

Creates a new grayscale color.

Too large luma values are masked to the valid range by setting the upper bits to 0.
