Struct footile::PathBuilder

pub struct PathBuilder { /* private fields */ }

Builder for Path2D.

Example

use footile::PathBuilder;
let path = PathBuilder::new()
                       .move_to(10.0, 10.0)
                       .line_to(90.0, 90.0)
                       .build();

Implementations

impl PathBuilder

pub fn new() -> PathBuilder

Create a new PathBuilder.

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, bx: f32, by: f32) -> Self

Move pen to a point.

• bx X-position of point.
• by Y-position of point.

pub fn line_to(self, bx: f32, by: f32) -> Self

Add a line from pen to a point.

• bx X-position of end point.
• by 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 A (current pen position), B (control point), and C (spline end point).

• bx X-position of control point.
• by Y-position of control point.
• cx X-position of end point.
• cy Y-position of end point.

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 A (current pen position), B (first control point), C (second control point) and D (spline end point).

• bx X-position of first control point.
• by Y-position of first control point.
• cx X-position of second control point.
• cy Y-position of second control point.
• dx X-position of end point.
• dy Y-position of end point.

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 build(self) -> Path2D

Build path from specified operations.
