Thanks to Rolf van Gelder of CAGE we have a new improved version of the Processing library to handle QRCodes we released a while ago
Rolf implemented a couple of really useful new features:
PImage generateQRCode(String content, int width, int height)
allows you to generate a new QRCode directly, without having to use a service like Kaywa anymore.
and then, the function
String decodeImage(boolean tryHarder, PImage img)
allows you to decode a QRCode directly from a PImage instance, instead of having to rely on a graphical file saved somewhere.
You can download the new version of the library here:
and keep on whatching out for news on the main page of the library
Thank you Rolf!
