Use the Hydrate static function method to create the object from its dehydrated form. The dehydrated form consists of a hash containing the object’s properties and values. The Hydrate and Dehydrate methods let you store the object state in memory and restore it later.

Representing an object as a hash is necessary for running ENVI analytics with the ENVI Task Engine.

See the ENVIHydrate function if you are creating a general IDL routine that will restore multiple object types.

For additional information, see "What are Hydrate and Dehydrate routines used for?" in the ENVI API Programming Guide.

This method is only available with the classified ENVI DoD plug-in.


Result = ENVINITFCSMRasterSpatialRef.Hydrate(DehydratedForm, ERROR=value)

Return Value

The result is a reference to a new object instance of the spatial reference.






Required. A string value of NITFCSMRasterSpatialRef indicating what object type the hash represents.


A long64 value specifying the number of lines of the source parent NITF file.


A long64 value specifying the number of samples (pixels) per image line of the source parent NITF file.


An encoded string containing all the sensor model state information.



Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See Manage Errors for more information on error handling in ENVI programming.
