[vtkusers] suggestion for a tweak in Cxx example: ReadAllPolyDataTypes.cxx / ReadAllPolyDataTypesDemo.cxx

[Heller M.O.]

Dear all,

I used the ReadAllPolyDataTypes.cxx example to create a little command-line tool for file conversion and noted that a small change may make the example code more robust against funny filenames i.e. filenames including multiple dots.

I think it could help to make the example a tad more robust if
line 70 of the ReadAllPolyDataTypes.cxx file was changed from:

std::string extension = vtksys::SystemTools::GetFilenameExtension(std::string(fileName));

to:

std::string extension = vtksys::SystemTools::GetFilenameLastExtension(std::string(fileName));


It took me as an absolute Cxx idiot a while to figure out what the problem was and how to address it.
(A similar change may also be useful for the ReadAllPolyDataTypesDemo.cxx example)

Best wishes, Markus
