Tif to PDF conversion error

[stirfrey]

I have a large number of tif's that I'm trying to convert to PDF using a simple command
"convert file.tif file.pdf"
I'm doing this on an Ubuntu Linux system. After a period of time the command errors with the message below.

Bad value 0 for "RowsPerStrip" tag. `_TIFFVSetField' @ error/tiff.c/TIFFErrors/568.

Most of the pages are converted, but in the resulting PDF there are some pages missing. Most of the files I had to convert worked just fine, but I have about 30 or so that are all giving this same error. I've done some googling and digging in the forum but not been able to find any similar errors. What would cause this and is there a way to fix it?

Thanks,

IM uses libtif to process TIFF files. I suppose your tiff files do not conform to proper structure. You could try to edit them with EXIFTOOL. Tiff files should not have a 0 value for RowsPerStrip.
