Envelope.fromXY constructor
- required double xMin,
 - required double yMin,
 - required double xMax,
 - required double yMax,
 - SpatialReference? spatialReference,
 
Creates an envelope based on the x,y coordinates with a spatial reference.
If the values for min parameters are bigger than max parameters then they are re-ordered. The resulting envelope always has min less than or equal to max.
Parameters:
xMin— The minimal x-value.yMin— The minimal y-value.xMax— The maximum x-value.yMax— The maximum y-value.spatialReference— The spatial reference for the envelope.
