Provides access to members that control the import/export operations components of a spatial reference system. IPRJSpatialReference is same as IPRJSpatialReferenceGEN.
Members
| Name | Description | |
|---|---|---|
 |
ExportSpatialReferenceToPRJ | Exports the spatial reference to a buffer. |
|
ImportSpatialReferenceFromPRJ | Defines the spatial reference from the specified ESRISpatialReference buffer. |
 |
PRJSpatialReferenceSize | The number of bytes required to hold the persistant representation of the spatial reference. |
IPRJSpatialReference.ExportSpatialReferenceToPRJ Method
Exports the spatial reference to a buffer.
Public Sub ExportSpatialReferenceToPRJ ( _
ByRef str As String, _
ByRef cBytesWrote As Integer _
)
public void ExportSpatialReferenceToPRJ (
ref string str,
ref int cBytesWrote
);
Description
Converts a spatial reference object into a PRJ file. A PRJ file stores the coordinate system information for a coverage, GRID, or TIN.
A sample representation (reformatted for display) is below.

IPRJSpatialReference.ImportSpatialReferenceFromPRJ Method
Defines the spatial reference from the specified ESRISpatialReference buffer.
Public Sub ImportSpatialReferenceFromPRJ ( _
ByVal str As String, _
ByRef cBytesRead As Integer _
)
public void ImportSpatialReferenceFromPRJ (
string str,
ref int cBytesRead
);
Description
Converts a PRJ file into a spatial reference object. A PRJ file stores the coordinate system information for a coverage, GRID, or TIN.

Parameters
Remarks
Not implemented for the GeographicCoordinateSystem or ProjectedCoordinateSystem coclasses. Use the ISpatialReferenceFactory:CreateESRISpatialReferenceFromPRJ method instead.
IPRJSpatialReference.PRJSpatialReferenceSize Property
The number of bytes required to hold the persistant representation of the spatial reference.
Public ReadOnly Property PRJSpatialReferenceSize As Integer
public int PRJSpatialReferenceSize {get;}
Description
Returns the size in bytes needed for a string representation of a PRJ file. A sample represetation (reformatted for display) is below.
