Reading QR images via Gemstone (server side Linux)

Ok, yesterday I posted a short message about creating QR codes on the server via Gemstone. In the afternoon I wanted to implement the reverse way: you have a picture on the server and you want to have the content of the QR code.

Actually here again under Ubuntu 14.04.x one has a package and a tool which does the main mart: “zbar-tools”.

Therefore simply: “sudo apt-get install zbar-tools” and after that installation you get a tool named “zbarimg” which does a simple “scan and decode bar codes from one or more image files”.

After that with MSKLibQREncode-MSK.5.mcz you get simple code to wrap this tool.
