Barcodes symbology

[WojTec]

I'm looking for barcades symbology like: Code 25 (all versions), Databar (all versions), Code 128, EAN 128, MSI and UK Plessey, post codes (Postnet, etc.), EAN-14, ITF-14, Telepen, Channel Code, LOGMARS.

What I need are encode tables (in binary format, because I'm confused if I see wide-narrow variant) and checksum algorithms. Any other routins I already have (reading and parsing input data, rendering, etc.).

I have informations about EAN 2/5/8/13, UPC, Code 39, Code 93 and some medical codes. And I'm interesting in others 1D.

I'm also interesting in 2D codes, but currently I want to learn about more 1D.

Could you share some informations? (Wikipedia is not trusted source in this case)

A good source is Turbopowers SysTools components at sourceforge. However, the information you are looking for is not presented on a silver platter. You actually have to dig into the code and understand it.

Yeah, this is problem, no informations, just sources (btw: all I saw are bad written). But how these guys wrote their code if zero descriptions?

I'm downloading SysTools :)

Ahoj, you get the standardization documents, e.g. from ISO.

I just got Telepen, but it's completely not clear :(

Jürgen Schlottke has one of the (the ?) best Barcode components for Delphi. If you buy his software, you'd get all the information you want. Again, as code, not on the silver platter.

As Union wrote, you have to purchase the definition (i.e. 'silver platter') from the ISO.

Where can I see component by this author?
