[Insight-developers] Proposal: Add more streaming IO with a base class

[Luis Ibanez]

Hi Brad,

This is great !,

A nice example of code reuse.

Writing an Insight Journals sound like a good idea to me.

Particularly because it will document the class and the design
for any future developers.

You could simply submit the same tests that you already have
in ITK, and state that the code is in the toolkit already and that
the paper is provided as a technical report for future developers.

This will be extremely useful as we go converting other ImageIO
classes to support streaming.


       Luis
