NDF_NEW
Create a new simple NDF
Description:
The routine creates a new simple NDF and returns
an identifier for it. The NDF may subsequently be manipulated with the NDF_ routines.
Invocation
CALL
NDF_NEW( FTYPE, NDIM, LBND, UBND, PLACE, INDF, STATUS )
Arguments
FTYPE = CHARACTER
(
)
(Given)
Full type of the NDF’s DATA component (e.g. ’_REAL’ or ’COMPLEX_INTEGER’).
NDIM = INTEGER (Given)
Number of NDF dimensions.
LBND( NDIM ) = INTEGER (Given)
Lower pixel-index bounds of the NDF.
UBND( NDIM ) = INTEGER (Given)
Upper pixel-index
bounds of the NDF.
PLACE = INTEGER (Given and Returned)
An NDF placeholder (e.g. generated
by the
NDF_PLACE routine) which indicates the position in the data system where the new NDF will
reside. The placeholder is annulled by this routine, and a value of NDF__NOPL will be returned (as
defined in the include file NDF_PAR).
INDF = INTEGER (Returned)
Identifier for the
new NDF.
STATUS = INTEGER (Given and Returned)
The global status.
Notes:
-
This routine creates a "simple" NDF, i.e. one whose array components will be stored in "simple" form
by default (see SGP/38).
-
The full data type of the DATA component is specified via the FTYPE argument and the data type of
the VARIANCE component defaults to the same value. These data types may be set individually with
the NDF_STYPE routine if required.
-
If this routine 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 routine should fail for any reason. In either event, the placeholder
will still be annulled. The NDF__NOID constant is defined in the include file NDF_PAR.
