The methods of the **Curve** class are listed below. For a complete list of **Curve** class members, see the Curve Members topic.

Register | Register a CurveType In Drawing3d.Curves the following 2d-Curves are registered Register(1, typeof(Line)); Register(2, typeof(Arc)); Register(3, typeof(Bezier)); Register(4, typeof(QSpline)); Register(5, typeof(Nurbs2d)); Register(6, typeof(BSpline)); |

registerAliases | Register "alias"-names for some types. |

Changed | This method is called, when the curve is changed. It fires the event OnChanged |

Clone | Produces an exact copy of the curve by using the BinaryFormatter. So you have to mark a new instance of Curve with the attribute [Serializable]. |

Cross | Overloaded. Crosses the Curve with an other curve by crossing the interpolating polygonarray. |

Derivation | This abstract method must be overridden. It returns the first deriavation of the function defined in the method Value. All parameter t are taken from the interval [fromParam,toParam]. |

Distance | Overloaded. This method calculates the distance of a LineType to a Curve only in case, when the distance is smaller then MaxDist, otherwise big will be returned. You can imagine a cylinders with radius MaxDist around the Curve. If the line goes through the "curved" cylinder, then the distance will be calculated and returned. |

Equals (inherited from Object) | |

FindType | Gets the associated type of an ID |

GetCrossList | Get a CrossList, which contains the crossing points with another curve?. The parameter param1 and param2 in CrossItem are converted to a curve parameter. |

GetHashCode (inherited from Object) | |

GetMaxrect | Overloaded. Gets a minimal rectangle, which contains a curve, transformed by a transformation. |

GetType (inherited from Object) | |

InsertPoint | Inserts a point at the position, which is given by Param. |

Invert | Inverts the direction of the curve by exchange A and B resp. Atang and Btang |

LengthToParam | Converts a length to a param, which can be used in the method Value. |

LoadFromStream | Loads A an B. |

Parallel | Returns a leftside parallel xyArray to the curve, which has a distance of width. |

ParamToLength | Calculates the length of a part of the curve, which is given from 0 to the value param. |

SaveToStream | Saves A an B. |

SetBorder | Overloaded. Set the border of the curve to the new start- and endpoints of the curve, whose are near to _A and to_B |

Slice | This method trims the curve to the part between "from" and "to". The base-method sets fromParam = from and toParam = to. In general this is not the best solution. So it is better to override this method without calling to the base method. |

ToArray | This method fills values, calculated by the function Value in an array, starting at index. |

ToString (inherited from Object) | |

ToXYArray | Gets an array of Resolution+1 interpolationpoints. |

Transform | Transforms a Curve with the transformation given by m. The method in the base class is empty. So you have to override this function, if you want to transform a Curve. |

Value | This abstract method must be overridden. It returns the function for a value t. public xy Value(double t){ return new xy(cos(t), sin(t)); } public xy Drivation(double t){ return new xy(-sin(t), cos(t)); }This example implements an unit circle. |

Finalize (inherited from Object) | |

getA | This is the virtual Get-Method of A. By default it calls 'Value(fromParam)'. |

getAtang | This method is the getMethod of the Atang-property, which retrieves the start tangent. By default Derivation(fromParam) is returned. |

getB | This is the virtual Get-Method of B. By default, it provides 'Value(toParam)'. |

getBtang | This method is the getMethod of the Btang-property, which retrieves the Endtangent. By default Derivaion(toParam) is returned. |

GetMaxrect | Overloaded. Gets the smaller rectangle, which contains the curve. |

getVisible | virtual getmethod of the property Visible |

MemberwiseClone (inherited from Object) | |

setA | This method is the setMethod of the A-property, which retrieves the StartPoint. This method is abstract and has to be overridden. |

setAtang | This method is the setMethod of the Atang-property, which retrieves the starttangent. This method is an abstract one and has to be overridden. |

setB | This method is the setMethod of the B-property, which retrieves the EndPoint. This method is abstract and must be overridden. |

setBtang | This method is the setMethod of the Btang-property, which retrieves the end tangent. This method is abstract and has to be overridden. |

setVisible | Virtual setmethod of the property Visible |
