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

GPR_$INQ_BITMAP_DIMENSIONS        GPR Calls         GPR_$INQ_BITMAP_DIMENSIONS


NAME
     gpr_$inq_bitmap_dimensions - returns the bitmap dimensions.

FORMAT
     gpr_$inq_bitmap_dimensions (bitmap_desc, size, hi_plane_id, status)

DESCRIPTION
     This routine returns the size and number of planes of a bitmap.

     A program can use the information returned by this call to retrieve the
     actual bitmap size.  This could be useful, for example, if the program
     specified a bitmap size that was too large for the display, causing a
     reduction in bitmap size.

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

   Output Parameters
     size Width and height of the bitmap, in gpr_$offset_t format.  This data
          type is 4 bytes long.

     hi_plane_id
          The identifier of the bitmap's highest plane, in gpr_$rgb_plane_t
          format.  This is a 2-byte integer.  To find the number of planes in
          the bitmap, add one to hi_plane_id.

     status
          Completion status, in status_$t format.
