Struct footile::Path2D

pub struct Path2D { /* fields omitted */ }

Path builder.

Example

use footile::Path2D;

let path = Path2D::default()
    .move_to(10.0, 10.0)
    .line_to(90.0, 90.0)
    .finish();

Implementations

impl Path2D

pub fn absolute(self) -> Self

Use absolute coordinates for subsequent operations.

pub fn relative(self) -> Self

Use relative coordinates for subsequent operations.

This is the default setting.

pub fn close(self) -> Self

Close current sub-path and move pen to origin.

pub fn move_to(self, x: f32, y: f32) -> Self

Move the pen to a point.

• x X-position of point.
• y Y-position of point.

pub fn line_to(self, x: f32, y: f32) -> Self

Add a line from pen to a point.

• x X-position of end point.
• y Y-position of end point.

pub fn quad_to(self, bx: f32, by: f32, cx: f32, cy: f32) -> Self

Add a quadratic bézier spline.

The points are:

• Current pen position: P_a
• Control point: P_b (bx / by)
• Spline end point: P_c (cx / cy)

pub fn cubic_to(
    self,
    bx: f32,
    by: f32,
    cx: f32,
    cy: f32,
    dx: f32,
    dy: f32
) -> Self

Add a cubic bézier spline.

The points are:

• Current pen position: P_a
• First control point: P_b (bx / by)
• Second control point: P_c (cx / cy)
• Spline end point: P_d (dx / dy)

pub fn pen_width(self, width: f32) -> Self

Set pen stroke width.

All subsequent path points will be affected, until the stroke width is changed again.

• width Pen stroke width.

pub fn finish(self) -> Vec<PathOp>

Finish path with specified operations.

Trait Implementations

impl Default for Path2D

fn default() -> Path2D

Returns the "default value" for a type.
