pbmupc - create a Universal Product Code PBM image
pbmupc
[-s1 | -s2] type manufacturer product
This program is part of Netpbm(1).
pbmupc generates an image of 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.
pbmupc produces an image 230 bits wide and 175 bits high. If you want a different size run the output through pamscale.
In addition to the options common to all programs based on libnetpbm
(most notably -quiet, see
Common Options
), pbmupc recognizes the following
command line options:
The -s1 and -s2 options 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||
