arcTo()

PathSpline::Builder & donner::svg::PathSpline::Builder::arcTo	(	const Vector2d &	radius,
		double	rotationRadians,
		bool	largeArcFlag,
		bool	sweepFlag,
		const Vector2d &	endPoint )

Add an elliptical arc to the path.

Parameters

radius	Radius before rotation.
rotationRadians	Rotation to the x-axis of the ellipse formed by the arc.
largeArcFlag	false for arc length <= 180, true for arc >= 180.
sweepFlag	false for negative angle, true for positive angle.
endPoint	End point.

circle()

PathSpline::Builder & donner::svg::PathSpline::Builder::circle	(	const Vector2d &	center,
		double	radius )

Draw a circle.

Parameters

center	Center of the circle.
radius	Radius.

closePath()

PathSpline::Builder & donner::svg::PathSpline::Builder::closePath

(

)

Close the path.

An automatic straight line is drawn from the current point back to the initial point of the current subpath.

curveTo()

PathSpline::Builder & donner::svg::PathSpline::Builder::curveTo	(	const Vector2d &	point1,
		const Vector2d &	point2,
		const Vector2d &	point3 )

Draw a bézier curve from the current point to point3, using point1 and point2 as anchors.

Parameters

point1	First control point.
point2	Second control point.
point3	End point of the curve.

ellipse()

PathSpline::Builder & donner::svg::PathSpline::Builder::ellipse	(	const Vector2d &	center,
		const Vector2d &	radius )

Draw an ellipse.

Parameters

center	Center of the ellipse.
radius	Ellipse radius, for both the x and y axis.

lineTo()

PathSpline::Builder & donner::svg::PathSpline::Builder::lineTo

(

const Vector2d &

point

)

Draw a line from the current point to a new point.

Parameters

point

End point of the line.

moveTo()

PathSpline::Builder & donner::svg::PathSpline::Builder::moveTo

(

const Vector2d &

point

)

Move the starting point of the spline to a new point, creating a new subpath.

If this is called multiple times in a row, subsequent calls will replace the previous.

Parameters

point

Point to move to.
