Detailed Description

A subpath of a Path.

A subpath is either open, or closed. There are two special kinds of closed subpaths, namely ellipses and closed B-splines.

Member Function Documentation

virtual Type ipe::SubPath::type ( ) const [pure virtual]

Return type of this subpath.

Implemented in ipe::Ellipse, ipe::ClosedSpline, and ipe::Curve.

bool SubPath::closed ( ) const [virtual]

Is this subpath closed?

Default implementation returns true.

Reimplemented in ipe::Curve.

const Ellipse * SubPath::asEllipse ( ) const [virtual]

Return this object as an Ellipse, or 0 if it's not an ellipse.

Reimplemented in ipe::Ellipse.

const ClosedSpline * SubPath::asClosedSpline ( ) const [virtual]

Return this object as an ClosedSpline, or 0 if it's not a closed spline.

Reimplemented in ipe::ClosedSpline.

const Curve * SubPath::asCurve ( ) const [virtual]

Return this object as an Curve, or else 0.

Reimplemented in ipe::Curve.

virtual void ipe::SubPath::save ( Stream stream) const [pure virtual]

Save subpath to XML stream.

Implemented in ipe::Ellipse, ipe::ClosedSpline, and ipe::Curve.

virtual void ipe::SubPath::draw ( Painter painter) const [pure virtual]

Draw subpath (does not call drawPath()).

Implemented in ipe::Ellipse, ipe::ClosedSpline, and ipe::Curve.

virtual void ipe::SubPath::addToBBox ( Rect box,
const Matrix m,
bool  cp 
) const [pure virtual]

Add subpath to box.

Implemented in ipe::Ellipse, ipe::ClosedSpline, and ipe::Curve.

virtual double ipe::SubPath::distance ( const Vector v,
const Matrix m,
double  bound 
) const [pure virtual]

Return distance from v to subpath transformed by m.

Implemented in ipe::Ellipse, ipe::ClosedSpline, and ipe::Curve.

virtual void ipe::SubPath::snapVtx ( const Vector mouse,
const Matrix m,
Vector pos,
double &  bound 
) const [pure virtual]

Snap to vertex.

Implemented in ipe::Ellipse, ipe::ClosedSpline, and ipe::Curve.

virtual void ipe::SubPath::snapBnd ( const Vector mouse,
const Matrix m,
Vector pos,
double &  bound 
) const [pure virtual]

Snap to boundary of subpath.

Implemented in ipe::Ellipse, ipe::ClosedSpline, and ipe::Curve.
