Struct ConicalGradient 

pub struct ConicalGradient {
    pub center: LayerOffset,
    /* private fields */
}

A data structure to represent a conical gradient.

Fields

center: LayerOffset

The center point (Offset) of the gradient (relative to the Layer.offset).

Implementations

impl ConicalGradient

pub fn new( colors: ColorGradient, center: LayerOffset, angle: Option<f32>, ) -> ConicalGradient

Creates a conical gradient from colors, center, and an optional starting angle.

pub fn get_angle(&self) -> f32

The starting angle (in degrees) of the gradient.

A 0 degree angle is at 3 o’clock. This angle increases counter-clockwise.

pub fn set_angle(&mut self, val: f32)

Sets the starting angle in degrees.

Values are normalized into the inclusive range [0.0, 360.0).

pub fn get_color_at(&self, x: u32, y: u32) -> SolidColor

A helper function for renderers to get the color at a certain point.

The given x and y values are the coordinate of the pixel in the Layer (relative to Layer::offset).

Trait Implementations

impl Clone for ConicalGradient

fn clone(&self) -> ConicalGradient
