Struct Method 

pub struct Method {
    pub curve: f32,
    pub stretch: f32,
    pub levels: u8,
    pub lines: Option<Lines>,
}

How one style of a picture is made (the steps at the top of the module).

Fields

curve: f32

Each brightness b (0 to 1) becomes b ^ curve first: 1 leaves it, below 1 lightens the middle greys, above 1 darkens them.

stretch: f32

The share of pixels stretched to black at the dark end, and to white at the light end (0.03 for 3%); 0 leaves the greys as they are.

levels: u8

Each grey rounded to one of this many evenly spaced levels before the dither (black and white among them); 0 or 1 rounds nothing.

lines: Option<Lines>

The art’s own dark lines drawn black on top, if any.

Implementations

impl Method

pub const BAYER: Self

The plain method: the brightness stretched by 3% at each end, then the Bayer dither (the Playdate’s style A).
