[Insight-users] Possible bug in itkAnalyzeImageIO? : Gipl not being found

[Luis Ibanez]

Hi Raghavendra,

It looks like the GiplImageIO factory
is not being found.

Could you please double check the file

Insight/Code/IO

   itkImageIOFactory.cxx

and see if in line 99, the following
line is not commented out :


  ObjectFactoryBase::RegisterFactory( GiplImageIOFactory::New() );


This lines registers the Gipl reader/writer
in the factory mechanism.

(I'm assuming you are using ITK version 1.2)



Regards,



Luis
