Use:          CALL PGSIMI(INTP)

              INTP    The interpolation mode (INTEGER).

                        0 - no interpolation is performed
                        1 - bilinear interpolation

              Both pixel devices (e.g. the Ggi plot device) and PostScript
              image devices are supported. In the case of PostScript
              devices, interpolation is implemented in the PostScript
              language, which is not in all cases optimal. E.g. when
              a color map with discontinuities is used, or when BLANKs
              are present, results will be different.
