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.

Understood.

And photoshop for exemple, perfectly load and display ICCLAB jpegintiff files, with various subsamplings.

But only 8 bits depth... :-(((

Ouch. Adobe is usually pretty good about supporting formats, at least with decoding them.

I have some I can place somewhere in cyberspace.

Excellent, excellent. Merci beaucoup, mon ami généreux.

a "jpegintiff CIELAB affair" for any purpose other that what PhotoShop can do ( in turn save a monochrome file with a well defined calibrated L grayscale ) is basically... hazardous.

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.
