Add a class ZXing (this is the open source QR-code library we use, credits go to everyone involved in that). Add a static method with this signature QRImage(width:Integer; height:Integer; value:String):Image – and then you have access. In the application (a returns and reclamation system) where this was used first we added a derived attribute like so:

QRCode: Blob , DerivationOcl = ZXing.QRImage(300,300,’https://yourserver/Turnkey/AngularApp#/ToolInfo/’+self.Guid.asstring)
