virtual

Sets the x and y coordinates as well as the midpoint and sharpness of the control point corresponding to the index. Changing the y has no effect, it will always be 0.5

Implements vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

virtual vtkIdType vtkColorTransferControlPointsItem::AddPoint ( double * newPos )

virtual

Add a point to the function. Returns the index of the point (0 based), or -1 on error. Subclasses should reimplement this function to do the actual work.
