Folks,

The new data formats and new predictor now (partially) supported by
libtiff (you should grab development version from CVS). "Partially"
means that you should not try the new predictor on big-endian hosts, I
must solve one technical issue before it will be possible. But on
little-endian boxes you can start playing. I should note that the new
predictor works very well, in some cases I have ~25% reduction of
image sizes over the plain LZW/ZIP methods.

Also it will be helpful to test libtiff output with the independent
application, so those who have CS2, are welcome to try this out.

Best regards,
Andrey
