Member Function Documentation

type()

SubPath::Type Ellipse::type ( ) const

virtual

Return type of this subpath.

Implements ipe::SubPath.

References ipe::SubPath::EEllipse.

asEllipse()

const Ellipse * Ellipse::asEllipse ( ) const

virtual

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

Reimplemented from ipe::SubPath.

matrix()

Matrix ipe::Ellipse::matrix ( ) const

inline

Return matrix that transforms unit circle to the ellipse.

Referenced by save().

save()

void Ellipse::save ( Stream &  stream ) const

virtual

Save subpath to XML stream.

Implements ipe::SubPath.

draw()

void Ellipse::draw ( Painter &  painter ) const

virtual

Draw subpath (does not call drawPath()).

Implements ipe::SubPath.

References ipe::Painter::drawArc().

addToBBox()

void Ellipse::addToBBox ( Rect &  box, const Matrix &  m, bool  cp  ) const

virtual

Add subpath to box.

Implements ipe::SubPath.

References ipe::Rect::addRect().

distance()

double Ellipse::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::Arc::distance().

snapVtx()

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

virtual

snaps to center of ellipse.

Implements ipe::SubPath.

snapBnd()

void Ellipse::snapBnd ( const Vector &  mouse, const Matrix &  m, Vector &  pos, double &  bound  ) const

virtual

Snap to boundary of subpath.

Implements ipe::SubPath.
