[vtkusers] vtkPointPicker and Tcl interface,..

[Miguel Angel Rodriguez Florido]

	Hi vtkusers,

	I've done a simple example with a tcl procedure that reads a tiff image 
(vtkTIFFReader) and a vtkPointPicker joined to the vtkTkRenderWidget 
where I display this image.

	The picker works well, but when I tried to access to any information of 
the image (i.e. "puts [myImage GetCenter]" or "puts [myImage 
GetDimensions]) in the tcl function associated to the picker (Mypicker 
AddObserver EndPickEvent PickRegion) I got this message:
----------
Generic Warning: In 
/usr/local/vtk-5.1.0/VisualizationToolkit-5.1.0/Common/vtkTclUtil.cxx, 
line 723
Error returned from vtk/tcl callback:
PickRegion
  at line number 1
----------
without any more information, so its so difficult to trace what's happening.

Any idea?.

Thank you very much in advance.
