Is the size of the positioning markings adjustable? #40

Describe the option you are trying to implement I want to create QR code with smaller positioning markings (the 3 shapes on the top left and right and bottom left)

Is there any way to adjust the size of them and let the content grow a bit more?

Thanks for the library! Awesome job!

The size of positional eyes is defined by QR code standard - 7 dots. You can make its middle ball smaller/bigger and frame stoke thinner/thicker but not the size of it in general

Technically you can create custom shapes and use any size you want for it ignoring one that comes as a parameter, but there is no guarantee you would able to scan such a code

And in v2.0 alpha there is a magic function scale that you can apply to any shape and by combining it with .asBallShape() / .asFrameShape you can create nice scaled shapes with center pivot. But again this can negatively reflect on the functionality of this code

Understood, thank you very much for your replies! 🍻 The issue I had was data was too small so there were few dots and large positioning markings and it looked a bit weird. I've added some correction level so it generates more points and it pushed them a bit and scaled down, and looks better now. Good info you shared, I'll try to avoid it for now, just to make sure I'm not affecting functionality for aesthetics
