2010.09.10 16:13 "most libtiff utilities failing with multi-image tiffs", by Duane Evenson
I'm creating a bunch of multi-image tiffs from my scanner using HP Solution Center. tiffsplit and most other utilities fail with some tiffs. tiffdump is the only utility that works on all the files. The error I get is 'Error fetching data for field "BitsPerSample".' Imagemagick's convert is able to split the files, although it is very slow. I'd like to use the more speedy libtiff utilities. Does anyone know what the problem is? Here is the results of my tests looking for a common denominator. The bad files are clumped together when sorted by file size. Between 2 GB and 2.6-3.5 GB, the libtiff ulities fail. Still, there are three OK files with even larger sizes than the bad ones, so size may not be the problem.
