Auto size and how to set it

[MicheleNutmeg]

Hi guys,
I've seen that in release 0.9.0 it has added support for auto selecting qrcode size up to 40 but I've also seen that the default size is 4.

what value should I use for the size property to auto select the size?

if this code is setting an auto size RQRCode::QRCode.new("http://github.com/") then when is the default value used?

Cheers

The default value is not used any longer. If you exclude the size the code will use the smallest possible qrcode size.
