I'm trying to convert some tiff-images I receive after an scan and OCR operation. Unfortunately this doesn’t seem to work.
Apparently I have two problems:
1.Compression Scheme: Old-style JPEG
Some tiff-files have an unsupported compression: Old-Style JPEG
I can’t figure out how to get of that. Does anybody know a tool that remove-unpack- uncompress these images
2. Bits/Sample: 8
If I convert jpg to tiff (with imagemagick) and try to use compression, I can’t do this because I get a warning: Bits/sample must be 1 for Group 3/4 encoding/decoding.
Is there a method to reduce the bits/sample?
Can anybody help me out or at least show me some directions where to start looking?
