I use libtiffv3.6.1 with libtiff-lzw-compression-kit1.5 on MacOSX, and when I insert IPTC data with ImageMagick6.0.0 and run tiffinfo on my image I get:

TIFFReadDirectory: Warning, gc.tif: wrong data type 1 for "RichTIFFIPTC"; tag ignored.

Daniel,

I don't know anything about IPTC, but I would suggest using tiffdump to dump the contents of your file. It will give low level details of all fields that can be useful for debugging problems like this.

Putting a file demonstrating the problem somewhere people can download it (by http or ftp) would also be helpful if you want help diagnosing the problem.

Does anyone already had such a problem? On PC windows, it works fine.

"On PC windows" is not a very specific statement. I gather some windows application has no problem with the file? What application? Does it properly read the IPTC info? The message you see are all just warnings. I would expect a libtiff based application to read the image though the IPTC info might be ignored.

Best regards,
