PBMUPC

NAME

      pbmupc - create a Universal Product Code bitmap

SYNOPSIS

      pbmupc [-s1|-s2] <type> <manufac> <product>

DESCRIPTION

      Generates a Universal Product Code symbol.  The three arguments are: a
      one digit product type, a five digit manufacturer code, and a five
      digit product code.  For example, "0 72890 00011" is the code for
      Heineken.
      The -s1 and -s2 flags select the style of UPC to generate.  The
      default, -s1, looks more or less like this:
       ||||||||||||||||
       ||||||||||||||||
       ||||||||||||||||
       ||||||||||||||||
      0||12345||67890||5
      The other style, -s2, puts the product type digit higher up, and
      doesn't display the checksum digit:
       ||||||||||||||||
       ||||||||||||||||
      0||||||||||||||||
       ||||||||||||||||
       ||12345||67890||
      As presently configured, pbmupc produces a bitmap 230 bits wide and
      175 bits high.  The size can be altered by changing the defines at the
      beginning of the program, or by running the output through pnmenlarge
      or ppmscale.
