# Gimp.Image.prototype.metadata_save_filter

    function metadata_save_filter(mime_type: String, metadata: Gimp.Metadata, flags: Gimp.MetadataSaveFlags, file: Gio.File): Gimp.Metadata {
        // Gjs wrapper for gimp_image_metadata_save_filter()
    }

Filters the metadata retrieved from the image with [method@Gimp.Image.metadata_save_prepare], taking into account the passed flags.

*Note: There is normally no need to call this function because it's already called by [class@ExportProcedure] after the `run()` callback.*

Note that the image passed to this function might be different from the image passed to `Gimp.Image.prototype.metadata_save_prepare`, due to whatever file export conversion happened in the meantime

This can be used as an alternative to core metadata handling when you want to save metadata yourself and you need only filtering processing.
