Struct GradientAlignment 

pub struct GradientAlignment {
    pub x: f64,
    pub y: f64,
}

A normalized [-1, 1] x [-1, 1] position, ported from dart:ui’s Alignment — the coordinate space a Flutter LinearGradient’s begin/end and a RadialGradient/SweepGradient’s center are expressed in.

Fields

x: f64

y: f64

Implementations

impl GradientAlignment

pub const CENTER_LEFT: Self

Alignment.centerLeft — LinearGradientSpec’s default begin.

pub const CENTER_RIGHT: Self

Alignment.centerRight — LinearGradientSpec’s default end.

pub const CENTER: Self

Alignment.center — RadialGradientSpec/SweepGradientSpec’s default center.

pub fn within_rect(&self, origin: Point, size: Size) -> Point

Alignment.withinRect: map this [-1, 1] position into the window-space box at origin/size — x_px = origin.x + (1+x)/2 * width, likewise for y. origin is window-space (matching ButtonSurface::origin) because a brush’s own coordinates, unlike a PaintScene path, are never auto-translated by the scene’s origin argument — see this module’s PaintScene gradient-support finding.
