Struct Level 

pub struct Level {
    pub pitch: f64,
    pub first: Point,
    pub alpha: f64,
    pub weight: f64,
}

One lattice of dots, ready to paint.

Fields

pitch: f64

The gap between neighbouring dots, in screen pixels.

first: Point

The first dot at or after the canvas’s top-left corner, in canvas pixels. Every other dot of this level is a whole number of pitches from it.

alpha: f64

How present this level is: 0 draws nothing, 1 draws it in full.

weight: f64

0 draws a fine dot, 1 a heavy mark, in between while this level is taking over the role of the one below it.

Implementations

impl Level

pub fn radius(self) -> f64

pub fn visible(self) -> bool

Whether this level is worth asking the painter for.

pub fn heaviness(self) -> f64

How much of the heavy ink this level’s dots are mixed from, as a percentage for color-mix. The rest is the fine ink.
