can't read needled data qr/matrix code (application in the field of industry)

[JaOe7536]

hi, I was wondering what would it take to make zxing-js able to read qr and data-matrix codes like the one below:

does someone has a similar case and want to coop for implementation?
thanks, jacob

Have you found any lib in any language capable of reading that?

not yet, but wouldn't it great to be the first? ;)

Sure it would be nice, haha. We can read some pretty strange QR codes, maybe with some configuration the lib can handle these too.

I will try to get information from the makers of these qr codes, especially if they have thought about compatibility with code readers... ;)

Have you tried scanning them with the DataMatrixReader?

I've tried it with the Multi-format (1D/2D) example - it seems that a code consisting of dots instead of squares does not get recognized.

What formats you choose for multi-format reader?

just the live preview example (https://zxing-js.github.io/library/examples/multi-camera/), the initialization is the same as we would do it in our use cases

I tried the ZXing Angular Scanner demo and it couldn't read it in my Xiaomi Mi 9 SE.

Is there any progress on this topic? I've got a case where we have DMC-codes which are "needled" in some sort. One rectangle in a DMC consists of 4 circles like in the picture below.

Hey! I did not investigate this issue yet, sorry.
