Dear Andrey,

Thanks for the fast response. I was using libtiff 3.5.7 on Solaris 8. I upgraded to libtiff 3.6.1. Same result.

However taking cue from your response that hinted of no similar problems that have been encountered in libtiff, I did some more checking. It turns out that netpbm's pnmdepth is the trouble maker. I used it as an intermediate step to achieve tiff color reduction to 4 colors. tiffsplit -> tifftopnm -> pnmdepth -> pnmtotiff -> tiffcp

Somehow it produces weird code (double error) that is viewable on multipaged tiffs (only the first page) but it is not viewable with single page tifs. I apologize for the noise I created. BTW do you know of any good opensource unix color reduction utility for tiffs (command line preferably)?

Thanks,
