Today I discovered one of the leading producers of OldStyle JPEG (COMPRESSION=6) - Pixel Translations (www.pixtran.com). When I contacted them to ask why they continue to produce this stype of JPEG compressed TIFF when Adobe had documented COMPRESSION=7 method almost a year ago, they replied:

"Compression type 7 does not adhere to the latest TIFF specification (version 6.0) for JPEG data. We support the JPEG compression format type 6 from that specification."

It's in the interest of all libtiff users that we get producers of OldStyle JPEG to update their broken software. How about sending an nice email to support@pixtran.com asking them to update their software to Adobe TIFF Technical Note 2 specifications.
