[Insight-users] DivideImageFilter and VectorImage

[Luis Ibanez]

Hi Emmanuel,

Thanks for pointing this out.

We have now updated the NumericTraits for the VariableLengthVector,
and added a test for the DivideImageFilter using a VectorImage
divided by a scalar image:

http://www.itk.org/cgi-bin/viewcvs.cgi/Testing/Code/BasicFilters/itkDivideImageFilterTest2.cxx?rev=1.1&root=Insight&view=log


We are still having some quircks with Visual Studio 6.0 though...
(Ah!, the joy of VS6.0 ...)


Please give it a try and let us know if you find any problem.


    Thanks


        Luis
