virtual bool ipe::Curve::closed |
( |
|
) |
const [inline, virtual] |
Is this subpath closed?
Default implementation returns true
.
Reimplemented from ipe::SubPath.
const Curve * Curve::asCurve |

const [virtual] |
void Curve::save |
( |
Stream & |
stream |
) |
const [virtual] |
void Curve::draw |
( |
Painter & |
painter |
) |
const [virtual] |
Draw subpath (does not call drawPath()).
Implements ipe::SubPath.
void Curve::addToBBox |
( |
Rect & |
box, |

const Matrix & |
m, |

( |
const Vector & |
v, |
|
|
const Matrix & |
m, |
|
|
double |
bound | |
|
) |
| | const [virtual] |
Return distance from v to subpath transformed by m.
Implements ipe::SubPath.
void Curve::snapVtx |

const Vector & |
mouse, |
|
|
const Matrix & |
m, |

| | const [virtual] |
int ipe::Curve::countSegments |
( |
|
) |
const [inline] |
Return number of segments. This does not include the closing segment for a closed path.
Return segment.
If i is negative, elements from the end are returned. The closing segment of a closed path is not accessible this way (use closingSegment() instead)!
Returns the closing segment of a closed path.
Since the closing segment isn't actually stored inside this object, you have to provide a length-2 vector for the control points.
This method panics if the Curve is not closed.
void Curve::appendSegment |
( |
const Vector & |
v0, |
|
|
const Vector & |
v1 | |
|
) |
| | |
Append a straight segment to the subpath.
Append elliptic arc to the subpath.
Append quadratic Bezier spline.
void Curve::appendSpline |
( |
const std::vector< Vector > & |
v |
) |
|
void Curve::setClosed |
( |
bool |
closed |
) |
|
Set whether subpath is closed or not.
