Operation GM_Envelope
envelope (), in Class GM_Object
Documentation
The operation "envelope" shall return the minimum bounding box for this GM_Object. This shall be the coordinate region spanning the minimum and maximum value for each ordinate taken on by DirectPositions in this GM_Object. The simplest representation for an envelope consists of two DirectPositions, the first one containing all the minimums for each ordinate, and second one containing all the maximums. However, there are cases for which these two positions would be outside the domain of validity of the object's coordinate reference system. This operation is included here only as an interface, as applications may chose to implement in different manners.
