==================================

.. py:method:: geodata.mask.Mask.find_inner_bound(layers: Optional[str] = None) -> tuple[float, float, float, float]

   Find the bounding box that's within specified layers.

   :param layers: The list of layers to find inner bound.
                  If not specified, select all layers in the object.
   :type layers: list

   :returns: A bounding box `(minx, miny, maxx, maxy)`
             that represents the bounding box that bound the joint region.
   :rtype: tuple[float, float, float, float]
