Enum Base 

pub enum Base {

    White,
    Dither25,
    Dither50,
    Dither75,
    DiagonalUp,
    DiagonalDown,
    HLines,
    VLines,
    Checker2,
}

One of the fixed patterns, before any inversion: black and white solids, three ordered dithers, and four kinds of line.

Variants

Black

Every pixel black.

White

Every pixel white.

Dither25

A quarter of the pixels black, Bayer ordered.

Dither50

Half the pixels black, Bayer ordered: a one-pixel checker.

Dither75

Three quarters of the pixels black, Bayer ordered.

DiagonalUp

Black lines rising to the right, one pixel in four.

DiagonalDown

Black lines falling to the right, one pixel in four.

HLines

Black rows, one in four.

VLines

Black columns, one in four.

Checker2

A checker of 2 × 2 squares.
