Provides access to members that control the import/export operations components of a spatial reference system. This interface has been deprecated and IESRISpatialReferenceGEN should be used.
This interface can be used by developers who are familiar with the Projection Engine format for persisting string representations of these components. The ESRISpatialReferenceSize property returns the number of bytes required to hold the projection engine string representation of object implementing this interface. This number is guaranteed to be large enough but may be larger than needed. The number returned from ExportToESRISpatialReference is the exact number of bytes used in the buffer to hold the string. The example code, which demonstrates how to use this method, expects that a valid SpatialReference object has already been created.
The ImportFromESRISpatialReference method defines a spatial reference from its Projection Engine string representation. If you open up a PRJ file in Notepad that contains the string description of a ProjectedCoordinateSystem, you will see something like (but as a single line):
PROJCS["Test",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984", SPHEROID["WGS_1984",6378137,298.257223]],PRIMEM["Greenwich",0], UNIT["Degree",0.0174532925199433]],PROJECTION["Mercator"], PARAMETER["false_easting",1000000],UNIT["Foot",0.3048]]
|ESRISpatialReferenceSize||The number of bytes required to hold the persistant representation of this spatial reference component.|
|ExportToESRISpatialReference||Exports this spatial reference component to a buffer.|
|ImportFromESRISpatialReference||Defines this spatial reference component from the specified ESRISpatialReference buffer.|
