   ByVal mode As Integer, _
   ByVal dSize As Double _
) As Integer

Parameters

prjOut

The named Coordinate Reference System to create, or replace.

prjIn

The named Coordinate Reference System to copy.

mode

The units of dSize. This parameter must be set to 0, which means that dSize is specified in metres.

dSize
