  The bar codes

OPENBARCODES project



Here, all is under GPL - GNU license , open source and completely free...


Version francaise

I had to get interested in bar codes for working reasons. Surprise ! there is nothing free on the net, it seems awfully intricate and we consider to have to buy a heap of special tools. In fact, after studying some scattered documentation all becomes very easy. I have made my tests with a basic materiel : HP laserjet 6L printer to 300dpi, Canon S600 inkjet printer and hand bar codes DC 200 (The first price from JR informatique). In the following pages I will provide you all the software parts... free as usual.!
There is heaps of bar code types, I have only chosen a few types :

3 of 9 code(Also named code 39)

Very simple, alphanumeric and ideal for a personnal use

EAN13 code (Also named Gencod)

Without this code the great distribution maybe would not be so large !
(UPC-A and EAN8 are also in this page)

128 code(Also named EAN 128)

A complex code which can encode all the alphabet in a very concise mode.

2 of 5 interleaved code
 

A numeric code which is used by EAN in ITF14 code.

PDF417 code

A two dimensionnal bar code which can encode more than 1000 bytes.

Datamatrix code

A two dimensionnal bar code which can encode more than
2000 characters on a very small array.

WORK IN PROGRESS

OPENBARCODES project

It's a zip file gathering the whole of the downloads available on the pages of the different symbologies (sources whithout installer) but also the encoding functions in  a DLL written in C++
