[Insight-users] error in DiscreteGaussianImageFilter

[Ruben Schilling]

Hi all,

if not an error, it is at least completely misleading:

When you try to give an "unsigned int" templated image to the  
DiscreteGaussianImageFilter (well, the itk manpages seem to at least  
not forbid that) you get an awkward (!) error message saying (on my  
OS X system):

terminate called after throwing an instance of 'itk::ExceptionObject'
   what():  /Users/schillin/InsightToolkit-3.2.0/Code/Common/ 
itkMultiThreader.cxx:368:
itk::ERROR: MultiThreader(0x4020e00): Exception occurred during  
SingleMethodExecute
Abort trap


I found out by chance, that using an image templated over the type  
"float" produces the desired outcomes. The error message should  
clearly be more explicit, simply because it would save a programmer a  
great deal of time of error backtracking. I spent my time first  
looking for thread errors (which I really use in my program).
