Hi Jc,

I will get working on this and let you know when it is ready.

Thanks,

Hi Jc and David,

I think one reasonable solution would be to backport vtkScalarsToColors, but not backport vtkScalarBarActor. Instead we modify vtkScalarBarActor slightly to handle the new annotation functionality in vtkScalarsToColors. Then in slicer, we keep several sets of vtkStringArrays around and switch them in vtkScalarsToColors when needed. This way when we transition to vtk6.0, there will be minimal changes.

Thanks,

Kevin

I would not backport vtkScalarBarActor, but you could backport vtkScalarsToColors pretty easily and use it to store color names... that's where they are stored in VTK6.
