Enum zng_color::gradient::LinearGradientAxis

pub enum LinearGradientAxis {
    Angle(AngleRadian),
    Line(Line),
}

The angle or line that defines a linear gradient.

Examples

let angle_gradient = linear_gradient(90.deg(), [colors::BLACK, colors::WHITE]);
let line_gradient = linear_gradient((0, 0).to(50, 30), [colors::BLACK, colors::WHITE]);

Variants

Angle(AngleRadian)

Line defined by an angle. 0º is a line from bottom-to-top, 90º is a line from left-to-right.

The line end-points are calculated so that the full gradient is visible from corner-to-corner, this is sometimes called magic corners.

Line(Line)

Line defined by two points. If the points are inside the fill area the gradient is extended-out in the same direction defined by the line, according to the extend mode.
