[Insight-users] exceptions with metaImage

[Stephen R. Aylward]

Thanks for pointing this out.

We are very happy with the metaImage file format (for images, spatial 
objects, scenes, etc.); however, the code we are using to read/write in 
that format is quite "outdated."

Thanks for creating the bug report.  It is about time we update the C++ 
implementation for metaIO.  We can add exceptions, improve the 
programming style and improve the documentation.   It may be awhile 
before this happens, so in the meantime perhaps we can solve your 
problems with the temp solution that you suggested.

Let me see if I can find a volunteer to do this...

Thanks,
Stephen
