IMG_INDF- Return an image NDF identifier
- Description:
- This subroutine returns an NDF identifier for an image. This
identifier may be passed to subroutines from the NDF library
(see SUN/33) to perform lower-level operations on the data which
cannot be done using IMG subroutines.
- Invocation:
- CALL IMG_INDF( PARAM, INDF, STATUS )
- Arguments:
-
-
PARAM = CHARACTER * ( * ) (Given)
-
Parameter name (case insensitive).
-
INDF = INTEGER (Returned)
-
NDF identifier for the image.
-
STATUS = INTEGER (Given and Returned)
-
The global status.
- Notes:
- The NDF identifier returned by this subroutine should be annulled
(e.g. using NDF_ANNUL) when it is no longer required. The IMG
system will not perform this operation itself.
- If this subroutine is called with STATUS set, then a value of
NDF__NOID will be returned for the INDF argument, although no
further processing will occur. The same value will also be
returned if the subroutine should fail for any reason. The
NDF__NOID constant is defined in the NDF_PAR include file.
