Ooops, sorry, I was not clear enough : when I mentioned jpeg-6b, I was 
implicitly referring to libjpeg. I do agree with you 100%, standard 
librairies should be used thoroughly. Rewriting a JPEG lib from scratch 
would not make much sense considering that libjpeg or even libpng or libz 
(which I'm using in my own medical converter) are stable, portable, and 
maintained by teams.

What I was thinking of, is a vtkJpegCodec class as a object-oriented 
front-end for libjpeg.

Yep.
