[Insight-users] Re: A bug in ImageFileReader with complex

[Luis Ibanez]

Hi Martin,


Thanks for pointing this out.

You are right, the std::complex<> type cannot be used directly
as the pixel type for an image that is intended to be read into ITK.

The reason is that the ImageFileReader expect pixel types to have
number of traits defined. This pixel traits are to be defined in the
file:


        Insight/Code/IO/
           itkDefaultConvertPixelTraits.h


We just added the missing traits to this file, and committed the
changes to the CVS repository.


Please update your CVS checkout of ITK and let us know if you find
any further problems.


     Thanks



         Luis
