| Summary | 0012113: vtkColorTransferFunction::SetNodeValue() doesn't refresh function range | ||||||||
| Description | vtkColorTransferFunction::SetNodeValue() doesn't update the current range. The new X of the control point can be outside of the current range, however the range is not updated. Solutions: +vtkColorTransferFunction::SetNodeValue() can call SortAndUpdateRange() +Expose vtkColorTransferFunction::MovePoint() (it updates correctly the range) to the public API. If the user knows he just want to move the point, then he can call MovePoint() instead. | ||||||||
| Steps To Reproduce | vtkColorTransferFunction* ctf = vtkColorTransferFunction::New(); ctf->AddHSVSegment(0., 0., 1., 1., 0.3333, 0.3333, 1., 1.); ctf->AddHSVSegment(0.3333, 0.3333, 1., 1., 0.6666, 0.666, 1., 1.); ctf->AddHSVSegment(0.6666, 0.6666, 1., 1., 1., 0., 1., 1.); ctf->GetRange(); -> [0., 1.] double firstPoint[6]; ctf->GetNodeValue(0, firstPoint); firstPoint[0] = -1.; ctf->SetNodeValue(0, firstPoint); // move the first point in 0. to -1. ctf->GetRange(); -> [0., 1.] should be [-1., 1.] | ||||||||
| Additional Information | A work around (time consuming) is to use AdjustRange() after calling vtkColorTransferFunction::SetNodeValue(). | ||||||||

vtkColorTransferFunction::RemovePoint() doesn't refresh the range neither. |
