Barcode generator

Generates barcodes using the GNU barcode library.

File contains a barcode helper program (nice front-end for actual barcode graphics makers) and a php application for barcodes (using that helper program).

There is an online demo.

Barcode generator v1.3.4 - copyright (C) 1992,2002 Bisqwit (http://bisqwit.iki.fi/)
New versions and support at http://bisqwit.iki.fi/source/barcodetest.html
Usage:
    barcodehelper <stringtoencode> [encodingindex]

Encoding indexes are defined in /usr/include/barcode.h,
and should be as follows:

   0=any, 1=ean, 2=upc, 3=isbn, 4=code39,
   5=code128, 6=code128c, 7=code128b, 8=i25,
   9=raw code128, 10=codabar, 11=msi,
   12=plessey, 13=code93.
 (At least when this program was written.)

Output is text, and contains following lines:
  A <input>
  P <the barcode>
  T <text info>
  E <encoding name>
  X <width>
  M <margin>
 The barcode is a coded string that should be interpreted as follows:
    digit = width of bar/space (space is first)
    alphabet = width of bar (a=1,b=2,...) and also tells
               that there's no character below/above
    - = characters will be below
    + = characters will be above
 Text info is a coded string that contains groups of x:y:c
    where x is x-coordinate, y is y-coordinate and c is the
    character to be printed. Possibly prefixed with +/- as
    previously explained.
