Steve, I don't have an authoritative answer, but I believe that Microsoft Document Imaging uses the "old jpeg" method and I don't think it is possible for libtiff to read and write this format. TIFF and JPEG is basically a nightmare because the original JPEG in TIFF specification was poorly done. A proper new specification was prepared by Tom Lane (in TTN2) and that is what libtiff uses. But some applications still use the old method - the most notable of which is the damn Wang / Microsoft document imaging thingy in windows. Curse it! This will be my last missive on old jpeg support till my blood pressure returns to normal. :-) Best regards, -- ---------------------------------------+-------------------------------------- I set the clouds in motion - turn up | Frank Warmerdam, warmerdam@pobox.com light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | Geospatial Programmer for Rent
