Struct lib::CanvasRenderingContext2D

pub struct CanvasRenderingContext2D {}

Implementations

impl CanvasRenderingContext2D

pub fn arc(
    x: f32,
    y: f32,
    radius: f32,
    start_angle: f32,
    end_angle: f32,
    counter_clockwise: bool
)

adds a circular arc to the current sub-path. see CanvasRenderingContext2D.arc

Parameters

• ‘x’ - the horizontal coordinate of the arc’s center
• ‘y’ - the vertical coordinate of the arc’s center
• ‘radius’ - the arc’s radius. Must be positive
• ‘start_angle’ - the angle at which the arc starts in radians, measured from the positive x-axis
• ‘end_angle’ - the angle at which the arc ends in radians, measured from the positive x-axis
• ‘counter_clockwise’ - if true, draws the arc counter-clockwise between the start and end angles

pub fn arc_to(x1: f32, y1: f32, x2: f32, y2: f32, radius: f32)

adds a circular arc to the current sub-path, using the given control points and radius. The arc is automatically connected to the path’s latest point with a straight line, if necessary for the specified parameters. see CanvasRenderingContext2D.arcTo

Parameters

• ‘x1’ - the x-axis coordinate of the first control point
• ‘y1’ - the y-axis coordinate of the first control point.
• ‘x2’ - the x-axis coordinate of the second control point
• ‘y2’ - the y-axis coordinate of the second control point.
• ‘radius’ - the arc’s radius. Must be positive
