Problems with decoding DataMatrix #407

Open mal-coder opened 3 years ago

mal-coder commented 3 years ago

Hi,

I'm having issues with decoding a particular type of data matrix codes - printed on climbing equipment. The scanner seems not to recognize it at all.

Did anyone encountered such problem and could advise how could I fix it?

Thanks in advance.

Regards

This is a new type of rectangular Datamatrix as published here https://www.e-d-c.info/en/projects/dmre-en.html The support for this is limited yet even among commercial barcode reading software. I would also be interested if this project could add support for the new rectangular Datamatrix barcodes

Filip made some changes here (link below) to read this QR as an inverted image and it works! The only problem left is that only from the zoomed in photo. When trying to get it from a life stream it seems to be too small (at least with my phones) :/ https://github.com/Applifting/zxing-js/pull/1
