Corner radius for barcode data

[UVLabs]

Is it possible to create barcodes with corner radius like this?

Hi @UVLabs thank you for your suggestion. looks like a nice addition. I don't have the time to do this myself but I will mark this as an opportunity for contribution.

Hey @endroid, I would like to do this, also I would like to add possibility to change corner shape, to add an overlay if possible. What's the best place to start checking the code for such features to implement?

Hi @syntaxgirl you could create your own writer, like the ones created here https://github.com/endroid/qr-code/tree/master/src/Writer. As you can see in the PngWriter you can start by retrieving the matrix and then use that to build your drawing logic on. For the PNG writer this is a simple loop but for determining if you want round corners you probably want to check adjacent cells. Good luck!

I'm closing this ticket because of lack of input. However if anyone still wants to add this feature, feel free to reopen / make a PR.
