Detailed Description

This class implements the OdGi equivalent of an OdDbPolyline or "lightweight" polyline.

Remarks

Instances of this class are used to pass lightweight polyline data through the Teigha vectorization framework.

Member Function Documentation

elevation()

virtual double OdGiPolyline::elevation ( ) const

pure virtual

Returns the elevation for this entity.

getArcSegAt() [1/2]

virtual void OdGiPolyline::getArcSegAt ( unsigned int  index, OdGeCircArc2d &  arc  ) const

pure virtual

Returns the arc segment starting at the specified index.

getArcSegAt() [2/2]

virtual void OdGiPolyline::getArcSegAt ( unsigned int  index, OdGeCircArc3d &  arc  ) const

pure virtual

Returns the arc segment starting at the specified index.

getBulgeAt()

virtual double OdGiPolyline::getBulgeAt ( unsigned int  index ) const

pure virtual

Returns the bulge value for a specified point.

getConstantWidth()

virtual double OdGiPolyline::getConstantWidth ( ) const

pure virtual

Returns the constant width for this entity.

getDbPolyline()

virtual OdRxObjectPtr OdGiPolyline::getDbPolyline ( ) const

pure virtual

Returns the original OdDbPolyline object from which this OdGiPolyline was created.

getLineSegAt() [1/2]

virtual void OdGiPolyline::getLineSegAt ( unsigned int  index, OdGeLineSeg2d &  ln  ) const

pure virtual

Returns the line segment starting at the specified index.

getLineSegAt() [2/2]

virtual void OdGiPolyline::getLineSegAt ( unsigned int  index, OdGeLineSeg3d &  ln  ) const

pure virtual

Returns the line segment starting at the specified index.

getPointAt()

virtual void OdGiPolyline::getPointAt ( unsigned int  index, OdGePoint2d &  pt  ) const

pure virtual

Returns a specified point from this entity.

getWidthsAt()

virtual void OdGiPolyline::getWidthsAt ( unsigned int  index, double &  startWidth, double &  endWidth  ) const

pure virtual

Returns the start and end widths for a specified point.

hasPlinegen()

virtual bool OdGiPolyline::hasPlinegen ( ) const

pure virtual

Returns the PLINEGEN flag for this entity. If PLINEGEN is true, linetype generation will be patterned across the entire polyline, rather than being done for each segment individually.

hasWidth()

virtual bool OdGiPolyline::hasWidth ( ) const

pure virtual

Returns true if the vertices in this entity contain start and end width data, false otherwise.

isClosed()

virtual bool OdGiPolyline::isClosed ( ) const

pure virtual

Returns true if this polyline is closed, false otherwise.

normal()

virtual OdGeVector3d OdGiPolyline::normal ( ) const

pure virtual

Returns the normal vector for this entity.

numVerts()

virtual unsigned int OdGiPolyline::numVerts ( ) const

pure virtual

Returns the number of vertices in the entity.

ODRX_DECLARE_MEMBERS()

OdGiPolyline::ODRX_DECLARE_MEMBERS

(

OdGiPolyline

)

segType()

virtual SegType OdGiPolyline::segType ( unsigned int  index ) const

pure virtual

Returns the segment type at the specified index.

thickness()

virtual double OdGiPolyline::thickness ( ) const

pure virtual

Returns the thickness for this entity.
