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

[Raghavendra Chandrashekara]

Hi Luis,

There is a line registering the GiplImageIOFactory but it is on line 98,
this is the code:

void
ImageIOFactory::RegisterBuiltInFactories()
{
  static bool firstTime = true;

  static SimpleMutexLock mutex;
  {
    // This helper class makes sure the Mutex is unlocked
    // in the event an exception is thrown.
    MutexLockHolder<SimpleMutexLock> mutexHolder( mutex );
    if( firstTime )
      {
      ObjectFactoryBase::RegisterFactory( DicomImageIOFactory::New() );
      ObjectFactoryBase::RegisterFactory( MetaImageIOFactory::New() );
      ObjectFactoryBase::RegisterFactory( PNGImageIOFactory::New() );
      ObjectFactoryBase::RegisterFactory( VTKImageIOFactory::New() );
      ObjectFactoryBase::RegisterFactory( GiplImageIOFactory::New() );
      ObjectFactoryBase::RegisterFactory( AnalyzeImageIOFactory::New());
      firstTime = false;
      }
  }

}

Does it look correct to you? I'm using Release-1-2-0 also.

Thanks,

Raghavendra.
