Good. For Phatch we use pyexiv2 in two ways: lazily for batch processing (eg adding geodata, writing one tag, ...) or dumping all properties for the image inspector. >> - Does metadata.copy also copy previews? > > No. It optionally copies EXIF, IPTC and XMP metadata, but not the previews.

For Phatch we do our tests with Arabic characters: http://bazaar.launchpad.net/~stani/phatch/trunk/files/head:/tests/input/ It helped us to discover a lot of bugs. > For IPTC tags, see also the related > https://bugs.launchpad.net/pyexiv2/+bug/461847. > >> We are finishing the Phatch 0.2.* releases (our last stage is Windows >> and Mac installers) and for Phatch 0.3 we will use this.

Well as Phatch will be available on Windows and Mac, it should get even more testing audience ;-) >> Olivier, I don't know if you looked to the Phatch image inspector but >> it is a GUI frontend to pyexiv2 ;-) It allows you to edit metadata in >> a grid for images individually or collectively (by row). > > I remember looking at it when it was in its early stages of prototyping.

Ha great, thanks for the offer! I'll keep it in mind. I hope you won't regret.
