Hi Stephan,

it has been a while since we last talked.
I suggested a new lossless code for usage within your TIFF library.
Neither PackPNM nor the popular JPEG2000 has been implemented by now.

Today I also want to suggest a new codec.

It is fast. It is free. It is open-sourced.

BCIF by Stefano Brocchi

The caveat is that it supports 24-bit color images only by now.

The author would be interested in adding BCIF to your TIFF library.
What do you think?

It seems that you might mixup a couple of things, so you're likely talking to the wrong person because I'm not providing a TIFF library, thus I'm not associated to the authors of libTIFF, for example.

What I do provide are libraries for JPEG 2000 and JPEG XR, but these aren't open source, but commercial libraries you can only buy from my industry partners.

This said, they also provide a tiff reader library, but in the net effect, whether this might or might not be included is entirely up to customer demand, i.e. it is unlikely that much work will be done if there is no demand from the user.

However, there *is* something that can be done, though in a completely different direction maybe. The JPEG has currently an open call for new coding techniques where your technology would probably be presented and discussed. Of course, then, we would need to do core experiment (which usually ends up that I do the core experiments ;-). Such experiments measure not only compression performance on our core test set, but also include complexity measures, robustness, possibility for multi-core implementations etc. If successful, a standardization then of course opens the door to customers, which in the end leads to implementation in products.

Thus, if you're interested, you're welcome to come to the next JPEG meeting, which will be in Berlin in July this year.

Please let me know what you think,

Thomas
