gpr_inq_bitmap_proj_format(A) — Apollo Domain/OS SR10.4.1

GPR_$INQ_BITMAP_PROJ_FORMAT       GPR Calls        GPR_$INQ_BITMAP_PROJ_FORMAT


NAME
     gpr_$inq_bitmap_proj_format - returns the projection format for the
     specified bitmap.

FORMAT
     gpr_$inq_bitmap_proj_format (bitmap, projform, status)

DESCRIPTION
     This routine returns the projection format for the specified bitmap.

   Input Parameters
     bitmap
          The descriptor of the bitmap, in gpr_$bitmap_desc_t format.  This is
          a 4-byte integer that uniquely identifies the bitmap.

   Output Parameters
     projform
          A pointer to the projection format, which is in gpr_$proj_format_t
          format.  This data type is a record in Pascal, a structure in C, or
          an array in FORTRAN.  The projection format specifies which set of
          planes of the bitmap is active.

     status
          Completion status, in status_$t format.

NOTES
     Use this call to find the current projection format for the display bit-
     map.

     The concept of projections is only applicable to display bitmaps.

     To set the projection, call gpr_$initialize.

     To change the projection, call gpr_$allocate_projection.
