The prototype for gimp_metadata_encode_xmp() seems inconsistent to the pattern
of the other functions you listed. I would have expected it to be:
gboolean
gimp_metadata_encode_xmp (gint32 image_ID,
guint *xmp_size,
const gchar **xmp_block);
Example of use:
- An image containing both XMP and EXIF information is loaded
- Call gimp_metadata_encode_exif (image, exif_size, exif_block) to
load the EXIF block into the gimp metadata parasite.
- Call gimp_metadata_encode_xmp (image, xmp_packet) to merge the XMP
information into the gimp metadata parasite. If some properties are
present in both XMP and EXIF (this is very likely), the old EXIF
information is overwritten: XMP always takes precedence.
Are you proposing in step 2 of your "Example of use" above that it be done
automatically in the file load plug-ins? I think that would make sense. Any
XMP/EXIF data for an image should be converted to parasites on file load and
coverted back to XMP/EXIF data on file save.
