Raphael's plan, which makes sense to me, is that the metadata editor and metadata accessor functions will work exclusively with XMP, and that file plug-ins will translate between XMP and other metadata formats (IPTC, EXIF, DICOM, etc) on loading or saving, using interface functions supplied by the metadata system. So the interface functions xxx_metadata_store_exif() and xxx_metadata_generate_exif() only come into play when loading or saving a file with exif data. Fortunately the Adobe XMP specification completely defines the translation between EXIF data and XMP data, so the EXIF->XMP->EXIF round trip can be done without losing any information. > Hmm, so if I open an image, do some color corrections, but do not > rotate it, the orientation tag is supposed to change?

It *is* what the spec says, and it seems to me that the only reasonable assumption is that if the user looks at the image before saving it, what the user sees is what the user wants. I admit that for non-interactive use this might not always be the most desireable thing, and perhaps it is worth thinking about whether that should (or could) be handled differently. -- Bill ______________ ______________ ______________ ______________ Sent via the CNPRC Email system at primate.ucdavis.edu _______________________________________________ Gimp-developer mailing list Gimpfirstname.lastname@example.org http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer
