Detailed Description

Function Documentation

appendJoin()

void donner::svg::PathSpline::appendJoin	(	const PathSpline &	spline,
		bool	asInternalPath = false )

Append an existing spline to this spline, joining the two splines together.

This will ignore the moveTo comand at the start of spline.

Parameters

spline	Spline to append.
asInternalPath	True if the spline should be treated as an internal path, which means that markers will not be rendered onto its segments.

arcTo()

void donner::svg::PathSpline::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 of the x-axis of the ellipse.
largeArcFlag	False for arc length ≤ 180°, true for arc length ≥ 180°.
sweepFlag	False for negative angle, true for positive angle.
endPoint	End point of the arc.

circle()

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

Draw a circle (uses multiple curve segments).

Parameters

center	Center of the circle.
radius	Radius.

closePath()

void donner::svg::PathSpline::closePath

(

)

Close the path.

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

curveTo()

void donner::svg::PathSpline::curveTo	(	const Vector2d &	control1,
		const Vector2d &	control2,
		const Vector2d &	endPoint )

Draw a cubic Bézier curve from the current point to a new point.

Parameters

control1	First control point.
control2	Second control point.
endPoint	End point of the curve.

ellipse()

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

Draw an ellipse (uses multiple curve segments).

Parameters

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

lineTo()

void donner::svg::PathSpline::lineTo

(

const Vector2d &

point

)

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

Parameters

point

End point of the line.

moveTo()

void donner::svg::PathSpline::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.
