How to create a QR Code Version 14 (73x73modules)

Hi Matthias

This looks like a relatively easy patch to make. Probably adding min version and max version optional parameters which default to 1 and 40 then using those in the loop to find the min version at line 1525 of the script. Then you just use 14,14 for the parameters.

It would be great if you would open an enhancement report and if so inclined contribute the patch in case others hit the same requirement.

Cheers

Monte

But is there a way to create just version 14 codes regardless of the number of character? Maybe with a modified library?
