[vtkusers] Tcl and vtkLocal

[Stephen Reilly]

I had wondered about the "info commands" part before, so had completely left
out the statement and used the following (quite unsafe) code:

#vtkLocal.tcl start
package require vtk

::vtk::load_component vtkLocalTCL
package provide vtkLocal 4.0
#Finish

I know it would be quite bad to use this in the real world, but I had been
trying to see why the library wasn't loading. This, however, also gives rise
to the message (as does changing the "vtkAnyImageFilter" to
"vtkImageColouration"):
::vtk::load_component: vtkLocalTCL could not be found.

I know that the library builds correctly as, if I add it to the vtkPatented
build, I can use it. I think that for the time being this hack will have to
be enough for me.

Thanks for taking the time to help me out with this. I know it is a fiddly
question, and the answer is probably staring me right in the face.

Thanks again,
Stephen

vtkAnyImageFilter
