|  Public Types inherited from ipe::SubPath | |
| enum | Type { ECurve, EEllipse, EClosedSpline } | 
Subpath consisting of a sequence of CurveSegment's.
| Curve::Curve | ( | ) | 
Create an empty, open subpath.
| 
 | virtual | 
Return type of this subpath.
Implements ipe::SubPath.
| 
 | inlinevirtual | 
| 
 | virtual | 
Return this object as an Curve, or else 0.
Reimplemented from ipe::SubPath.
| 
 | virtual | 
Save subpath to XML stream.
Implements ipe::SubPath.
| 
 | virtual | 
Draw subpath (does not call drawPath()).
Implements ipe::SubPath.
Add subpath to box.
Implements ipe::SubPath.
Return distance from v to subpath transformed by m.
Implements ipe::SubPath.
| 
 | virtual | 
Snap to vertex.
Implements ipe::SubPath.
| 
 | virtual | 
Snap to boundary of subpath.
Implements ipe::SubPath.
| 
 | inline | 
Return number of segments. This does not include the closing segment for a closed path.
| CurveSegment Curve::segment | ( | int | i | ) | const | 
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)!
| CurveSegment Curve::closingSegment | ( | Vector | u[2] | ) | const | 
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.
Append a straight segment to the subpath.
Append elliptic arc to the subpath.
Append quadratic Bezier spline.
| void Curve::appendBezier | ( | const Vector & | v0, | 
| const Vector & | v1, | ||
| const Vector & | v2, | ||
| const Vector & | v3 | ||
| ) | 
Append cubic Bezier spline.
| void Curve::appendSpline | ( | const std::vector< Vector > & | v | ) | 
Append B-spline curve.
| void Curve::setClosed | ( | bool | closed | ) | 
Set whether subpath is closed or not.
