# Gimp.Image.prototype.metadata_save_prepare

    function metadata_save_prepare(mime_type: String, suggested_flags: Gimp.MetadataSaveFlags): Gimp.Metadata {
        // Gjs wrapper for gimp_image_metadata_save_prepare()
    }

Gets the image metadata for saving it using Gimp.Image.prototype.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.MetadataSaveFlags.thumbnail is determined by whether there was a thumbnail in the previously imported image.
