gimp_image_metadata_save_prepare ()

GimpMetadata *
gimp_image_metadata_save_prepare (gint32 image_ID,
                                  const gchar *mime_type,
                                  GimpMetadataSaveFlags *suggested_flags);

Gets the image metadata for saving it using gimp_image_metadata_save_finish().

The suggested_flags are determined from what kind of metadata (Exif, XMP, ...) is actually present in the image and the preferences for metadata exporting. The calling application may still update available_flags , for instance to follow the settings from a previous export in the same session, or a previous export of the same image. But it should not override the preferences without a good reason since it is a data leak.

The suggested value for GIMP_METADATA_SAVE_THUMBNAIL is determined by whether there was a thumbnail in the previously imported image.
