Hello Marius,

Hi Matt,

This change:
https://itk.org/gitweb?p=ITK.git;a=commitdiff;h=3e1d822985b9eb3548e4fb9891f6773452467a81
is breaking our code where we rely on the availability of the GenerateOutputInformation() function to read image info while avoiding to read the actual data. We use that information to select the correct reader from a list of instantiated readers.

I had a look, and indeed in the base class (ProcessObject) this function is protected, so I guess it qualifies as a bug that GenerateOutputInformation() was public previously. This change does break backward compatibility however.

Do you have a suggestion on how to fix this? I really would like to have functionality in the image readers that read the meta data only, and not the data itself.

Thanks for your advice,
Marius
