New Plugin - QR Code generator

[EddyCurrent]

Lloyd, et al,

I realised about 3am that I had set the minimum width to 1 which is fine for metric but not inches.
Please find version 1.1 attached where the minimum width is now 0.01

Only the plugin file is attached here.

@Dave,

Thanks for the info, it's always a good idea to use methods that suit you best.

I knew about the QR code generator in Inscape, because I was playing around with a
microcontroller and a web cam to read QR codes and barcodes there’s a few other s too.
That was a few years ago now, what I do remember is that some android apps were far better
at recognising the codes than others, another thing is that the QR code I did above had no errors
at a certain size, but resized, the read error rate went up to 30%, Inkscape tells you what that error is, maybe your library
has this function too, this would help avoiding settling on a dimension that is hard to read.
So if you have trouble reading a code with your phone then resizing it may help a lot.

Just saw this cool plugin and gave it a try following the steps in the original post.  Mine doesn't show the Generate or Cancel buttons.    Debug level 4 doesn't show any errors.  What am I doing wrong?  (No Unblock button in DLL properties.)

CamBam v1.0 64bit, Win10 Home, 22H2.

Bubba,
Back in the early '80s, I wrote the low-level machine-language code to decode a 'light pen' output reading the then-popular Code-39.  I found it to be quite an adventure, and I learnt a lot about how to scale things (in M/L!) over periods of acceleration or deceleration of the read.  (Remember, these were hand-scanned, so speed varied, even across a short 'code'.)

I find what you're doing very interesting, and I have a question:  How do the black 'hatch' lines between adjacent white elements of the code affect its readability?  Do they affect it at all? Some?  A lot?

Not sure it is readable by the phone, but you can do the following:

- generate a QR code with square only
- select all squares > Draw/surfaces/fill
- with the surfaces that remain selected > join

now you get an unique "plain" surface objet without lines.

@annuello .. no idea for your problem .. works OK for me.
