 * @short_description: Generic Export Options
 *
 * A class holding generic export options.

 * Note: right now, GIMP does not provide any generic export option to
 * manipulate, and there is practically no reason for you to create this
 * object yourself. In Export PDB procedure, or again in functions such
 * as [func@Gimp.file_save], you may just pass %NULL.
 *
 * In the future, this object will enable to pass various generic
 * options, such as ability to crop or resize images at export time.
