[Insight-developers] IO Question

[Luis Ibanez]

Hi Kent,

Does your reader relies on an external library ?

if not,
 you could safely put it in Insight/Code/IO

if, on the other hand, it depends on a library,
you may want to consider putting this library
in Insight/Utilities, and still placing the main
reader IO class in Insight/Code/IO

This is more or less  what DICOM, PNG and
MetaImage do.

It may be difficult to factorize behavior between
readers producing images as output and those
producing other ITK objects.  It is probably easier
for now to get your reader in the repository and
after that double check if there is any common
functioinality that can be factorized.
