>  Docs Center  >  ENVI API  >  ENVINITFCSMRasterSpatialRef::Dehydrate



The Dehydrate function method returns a hash describing this object. You can use this information in a later ENVI session to restore the object using the object’s static ::Hydrate method or the ENVIHydrate function.

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


Result = ENVINITFCSMRasterSpatialRef.Dehydrate(ERROR=value)

Return Value

This function method returns a hash containing the key/value pairs representing the current object state. You can build your own hash without instantiating an object. To see the required key/value pairs for the object see the object’s Hydrate method.





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.
