NDF_SIZE - Determine the size of an NDF   

Description:
The routine returns the number of pixels in the NDF whose identifier is supplied (i.e. the product of its dimensions).

Invocation:
CALL NDF_SIZE( INDF, NPIX, STATUS )

Arguments:
INDF = INTEGER (Given)
NDF identifier.
NPIX = INTEGER (Returned)
Number of pixels in the NDF.
STATUS = INTEGER (Given and Returned)
The global status.

Notes:
  • If this routine is called with STATUS set, then a value of 1 will be returned for the NPIX argument, although no further processing will occur. The same value will also be returned if the routine should fail for any reason.
