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||
