## Constructor & Destructor Documentation

## ◆ ClosedSpline()

ClosedSpline::ClosedSpline | ( | const std::vector< Vector > & | v | ) |

## Member Function Documentation

## ◆ type()

SubPath::Type ClosedSpline::type | ( |  | ) | const
| virtual

Return type of this subpath.

Implements ipe::SubPath.

References ipe::SubPath::EClosedSpline.

## ◆ asClosedSpline()

const ClosedSpline * ClosedSpline::asClosedSpline | ( |  | ) | const
| virtual

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

Reimplemented from ipe::SubPath.

## ◆ beziers()

void ClosedSpline::beziers | ( | std::vector< Bezier > & | bez | ) | const

References ipe::Bezier::closedSpline().

## ◆ save()

void ClosedSpline::save | ( | Stream & | stream | ) | const
| virtual

Save subpath to XML stream.

Implements ipe::SubPath.

References ipe::size().

## ◆ draw()

void ClosedSpline::draw | ( | Painter & | painter | ) | const
| virtual

Draw subpath (does not call drawPath()).

Implements ipe::SubPath.

References ipe::Painter::closePath(), ipe::Painter::curveTo(), and ipe::Painter::moveTo().

## ◆ addToBBox()

void ClosedSpline::addToBBox | ( | Rect & | box,
|  | const Matrix & | m,
|  | bool | cp
| ) |  | const
| virtual

## ◆ distance()

double ClosedSpline::distance | ( | const Vector & | v,
|  | const Matrix & | m,
|  | double | bound
| ) |  | const
| virtual

Return distance from v to subpath transformed by m.

Implements ipe::SubPath.

References ipe::Ellipse::distance().

## ◆ snapVtx()

void ClosedSpline::snapVtx | ( | const Vector & | mouse,
|  | const Matrix & | m,
|  | Vector & | pos,
|  | double & | bound,
|  | bool | cp
| ) |  | const
| virtual

Snap to vertex.

Implements ipe::SubPath.

## ◆ snapBnd()

void ClosedSpline::snapBnd | ( | const Vector & | mouse,
|  | const Matrix & | m,
|  | Vector & | pos,
|  | double & | bound
| ) |  | const
| virtual
