        subroutine ftg2di(ounit,group,nulval,dim1,nx,ny,
     &                    array,anyflg,status)

C       Read a 2-d image of i*2 values from the primary array.
C       Data conversion and scaling will be performed if necessary
C       (e.g, if the datatype of the FITS array is not the same
C       as the array being read).

C       ounit   i  Fortran output unit number
C       group   i  number of the data group, if any
C       nulval  i*2  undefined pixels will be set to this value (unless = 0)
C       dim1    i  actual first dimension of ARRAY
C       nx      i  size of the image in the x direction
C       ny      i  size of the image in the y direction
C       array   i*2  the array of values to be read
C       anyflg  l  set to true if any of the image pixels were undefined
C       status  i  returned error stataus
