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.

References Ellipse().

◆ 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.

References matrix().

◆ 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.

◆ 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.
