[vtkusers] Does VTK support loading MRC files ?

[Lassi Paavolainen]

Hi Marcus and Ashika,

BioImageXD has vtk reader for MRC file format available at:
http://bioimagexd.svn.sourceforge.net/viewvc/bioimagexd/bioimagexd/trunk/vtkBXD/Processing/vtkMRCReader.cxx?revision=1690
http://bioimagexd.svn.sourceforge.net/viewvc/bioimagexd/bioimagexd/trunk/vtkBXD/Processing/vtkMRCReader.h?revision=1690

We have used it without problems to read several mrc files. I've only had 
one file that it currently reads wrongly since vtkMRCReader doesn't handle 
different byte orderings at the moment. Format itself doesn't specify 
that, but its easy to conclude that from values read from MRC file. I plan 
to make that small change to reader soon.

Unfortunately its GPL licensed, but I think we can re-license it as BSD if 
needed.

Cheers,
Lassi Paavolainen
