  9.        *       Purpose:
  10.        *          This program takes an image file and
  11.        *          rounds if off by writing it to an new
  12.        *          file that has an even multiple of
  13.        *          rows and cols.

  17.        *          rtiff.c - read_tiff_image
  18.        *          gin.c - get_image_name
  19.        *          gpcips - get_parameters
  20.        *          numcvrt.c - get_integer
  21.        *          wtiff.c - create_allocate_tiff_file
