IPTC data not saved after Gimp editing
Fr@nk Stef@ni
Hello all,
I use a well thought image processing workflow
with many batch processing and scripts. Every time
I edit TIFF images (and probably others) in Gimp,
the IPTC data is thrown away by Gimp and will not
be saved in the resulting file.
This is bad .... but I have hope that someone here
knows a script or plugin or whatever to save IPTC data
in the image even after Gimp processing.
FWIF, it is *not* a solution to reopen processed
files with an EXIF/IPTC managing tool afterwards.
This would mess up an otherwise very efficient workflow.
The IPTC data is entered at the time of RAW processing
and transparently preserved throughout the whole workflow.
Except for the Gimp part :(
Any help appreciated!
TIA, Frank

is below an option?
1- extract all iptc to flat file with exiftool, before GIMP stage.
2- edit with GIMP
3- put IPTC info back in tiff file with exiftool, from flat file.

When I first thought about this workaround, I had the
impression that this is error prone and I had to keep
track of what I'm doing when hundreds of files are
involved.
But then again, I discovered that the exiftool part is
as easy as
exiftool -TagsFromFile original.tif edited.tif
so no additional (text) files are needed. In fact, all
writeable tags will be copyed this way and thus the
edited file (edited.tif) should refer rather the same
tags as the original version (original.tif).
This is not bad as I may write a wrapper script or
enhance the already existing scripts to check whether
certain tags are in a file. If they are not, I could
copy the tags from the original file.
Thanks for this helpful hint which leads me to the
right direction ... though it would be best if Gimp
itself cared for the tags it currently throws away.

Excellent! Thanks heaps for sharing!

exiftool -TagsFromFile original.tif -TagsFromFile edited.tif edited.tif
Rather that replacing the tags supplied by GIMP, the
above adds everything from the original to the edited
file.

I don't want Gimp to tag anything, so for my needs
copying everything from original.tif to edited.tif
works perfectly.
Just out of curiousity, do you know if and what tags
Gimp sets by itself, without telling the user?

You *should* want GIMP tags...

I use GIMP 2.7, which copies a full set of tags.
If you want to know what your particular version of GIMP
does, just run exiftool and a JPEG image you've written
with GIMP.

One quick addenda:
exiftool -overwrite_original -TagsFromFile original.tif edited.tif
otherwise you end up with edited.tif duplicated.

Which build of Gimp 2.7 are you using? And are you sure you are
getting IPTC keyword tags? I just tried 2.7.0 r28070 and it did not
seem to preserve the IPTC info.
