/**
 * GimpRunExportFunc:
 * @procedure:   the #GimpProcedure that runs.
 * @run_mode:    the #GimpRunMode.
 * @image:       the image to export.
 * @n_drawables: the number of drawables to export.
 * @drawables: (array length=n_drawables):   the drawables to export.
 * @file:        the #GFile to export to.
 * @metadata:    metadata object prepared for the mimetype passed in
 *               gimp_file_procedure_set_mime_types() if export_metadata
 *               argument was set in gimp_export_procedure_new().
 * @config:      the @procedure's remaining arguments.
 * @run_data: (closure): the run_data given in gimp_export_procedure_new().
 *
 * The export function is run during the lifetime of the GIMP session,
 * each time a plug-in export procedure is called.
 *
 * If a MimeType was passed in gimp_export_procedure_new(), then @metadata will be
 * non-%NULL and can be tweaked by the run() function if needed. Otherwise you
 * can let it as-is and it will be stored back into the exported @file according
 * to rules on metadata export shared across formats.
 *
 * Returns: (transfer full): the @procedure's return values.
 *
 * Since: 3.0
