Description Guenther M. Erhard 2009-10-25 12:21:42 UTC

Version:            (using KDE 4.2.4)
OS:                Linux
Installed from:    SuSE RPMs

Hi,

I've reported this bug already sometime ago and we thought that it is resolved now.
Because we have now a re-written code I think it is better to track this in a new bug report.

While testing the program I discovered that sometimes assigning or changing a color profile to a TIFF-16 worked and sometimes not. After a while I found out the cause:
If exiv2 0.17 (which is the lib version installed by default in kde) is used assigning the color profile works perfectly. Using version 0.18 or 0.18.2 (and recompiling libkexiv2 and digikam of course) is does not work. There is no difference whether exiv2 is installed via rpm or by compiling from source.

This is bad, because exiv2 0.17 does not support writing meta to TIFF.

This is why you need to report this problem in Exiv2 bugzilla.

Can you reproduce this problem to use Exiv2 command line program ? 

Can you post there the metadata contents of tiff file using exiftool, before and after to apply icc profile ?

Which version of digiKam you use ?

I don't know how to do this with exiv2.

We will revisit this one when #211758 is solved. May well be another symptom.

What's news about this file. Still valid ?
