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||
