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.

       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 pnmscale.

OPTIONS

       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||
