Quoting Jean-Yves Le Ridant <jean-yves.leridant@culture.gouv.fr>: > This lack of reference reader/writer/viewver is why I said to Joris > about trying ICCLAB ( I understand that ITULAB is "great"). Are these standards too new to be adequately documented? Are they controlled by patent-enforcing companies which are aggressive litigators? I DID try to find some reference images as well as a complete specification, but didn't find much at all. > The difference being only in the ab rescaling, > from a codec point of view, the process is the same.

I understand. It seems that the standard is too new and emergent to be very useful outside a very limited scope. I'm puzzled as to why it was embraced and adopted by the facsimile hardware vendors. Designing a "modern" facsimile system without computer-based documents management and processing firmly in mind seems mentally deranged. =R=
