Control points for vtkColorTransferFunction.
virtual bool UsingLogScale()
Returns true if control points are to be rendered in log-space.
static vtkColorTransferControlPointsItem * New()
Creates a piecewise control points object.
virtual vtkIdType RemovePoint(double *pos)
Remove a point of the function.
virtual void GetControlPoint(vtkIdType index, double *point) const
Returns the x and y coordinates as well as the midpoint and sharpness of the control point correspond...
virtual void SetControlPoint(vtkIdType index, double *point)
Sets the x and y coordinates as well as the midpoint and sharpness of the control point corresponding...
virtual vtkIdType AddPoint(double *newPos)
Add a point to the function.
virtual void DrawPoint(vtkContext2D *painter, vtkIdType index)
virtual void ComputeBounds(double *bounds)
