B4A Library [B4X] barcodeGenerator - Cross platform Barcode code generator

codeBarGenerator is a class that generates barcodes.

It is written in B4X and is compatible with B4A, B4i and B4J.

At the moment the class only generates barcode in EAN13, UPC-A and CODE128-B format, you can modify the class and improve it even more.

Versions

V1.02 - barcode in CODE128-B.
V1.01 - barcode in UPC-A.
V1.00 - barcode in EAN13.

Hi Lucas Siqueira!
Are you planning to add more formats?
Here is my contribution (code refactored).

Congratulations on the adjustments. I haven't tested them yet, but I know you always create spectacular codes.

You have complete freedom to create new barcode patterns.

Before I go search, can you point to me where do you get the logic to generate the barcodes?

I remember it was on Wikipedia, maybe I looked at something else on the internet too, but I'm not sure.

CODE128-B - https://en.wikipedia.org/wiki/Code_128
EAN13 - https://en.wikipedia.org/wiki/International_Article_Number
UPC-A - https://en.wikipedia.org/wiki/Universal_Product_Code

Lol completely coincidentally I was just regenerating a loyalty card barcode this evening to print out a nice sharp copy for a friend to use, and it occurred to me that the same online barcode generator could be used by your service as a safety net, or to supply barcodes that you haven't yet implemented in code:

https://barcode.tec-it.com/barcode.ashx?data=2796273991234&code=EAN13&dpi=142&imagetype=Png

After I'd printed out a copy of the barcode, I remembered that I still have the previous (expired) credit card with the same loyalty barcode on the back, so my friend's going to use that instead, and thus my printing and trimming efforts were unnecessary anyway.

A while back, I was working on a library that generated all kinds of barcodes using Canvas, improving the generation and display process based on existing work on the forum.

Barcodes - QR Codes, PDF417, Aztec Codes, Code11, Code39, Code93, EAN8, EAN13, and Code128

This is my first attempt at B4J. Have not tried to do anything special to the layout etc. The aim was to get back the correct binary strings to draw Code11, Code39, Code93, EAN8 and EAN13 barcodes with. All the code are in the main module as well as modules for each of the types of barcodes. The...

This reminded me of a PHP library?

Thanks.
When I free I will see if I can add other formats.
