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 be-
ginning 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 de-
fault, -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||
