[vtkusers] HELP! LookupTable

[Ali Calvert]

Hi, sorry if its a stupid question but I have the following bit of code:

vtkImageMapToColors map
 map SetInputConnection [reader GetOutputPort]
 map SetLookupTable [reader GetLookupTable]
 map SetOutputFormatToRGBA

I want to be able to find a colour at say index 180 so I could use the
GetColor method from vtkLookupTable.
However, the problem i am having is that the lookuptable has no name
therefore i cannot call the GetColor method.

Driving me a bit mad!

I would appreciate any help at all.

Thanks to all.
