micro Qr support

[edwardocano]

hi! do you plan to add micro qr to your library?

[nayuki]

Although I read the Micro QR Code section of the specification and understand the general effort needed to implement it, unfortunately the answer is no, for a variety of reasons:

• I have literally never seen a Micro QR Code out in the wild.
• The app I use (Android, Barcode Scanner, using ZXing library) doesn't seem to support scanning it.
• Micro QR has its own rules for stuff like the layout of function patterns, format bits, masks, error correction levels, supported segment modes. It requires a lot of custom code for little benefit. Whereas supporting QR Code versions 1 through 40 is pretty straightforward because they follow a pattern.

While we're on the topic of unpopular barcode formats, I've also skimmed the spec for the legacy QR Code Model 1. I would consider that an exercise to implement for historical completeness, just like Micro QR Codes - not for practical applications.

Note: On that same day that you asked this question about supporting Micro QR Codes, you also asked on a couple of other projects:

• micro qr x-hw/amazing-qr#71
• micro qr support lincolnloop/python-qrcode#201
• micro qr.  dlazaro66/QRCodeReaderView#181

Ok, thanks for your answare.
