2.0

  • migrated QR generator library to use Endoird QR-code instead of PHP QR Code (which is no longer in active development)
  • added the ability to change the color of the QR Code's foreground and background
  • added the ability to make the QR Code's background transparent
  • changed the size settings (this was neccessary due the changing QR libraries)
  • general code cleanup and documentation

    1515This allows you to continuously reuse your QR codes on printed or linked marketing material... you can change the destination you're sending your users to without ever having to change the artwork you're using to promote it.
    1616
    17 This plugin is the second incarnation of the QR Code Redirect plugin.  It was developed to be self contained after the Google Chart API deprecated its QR Code generation service.  Instead of relying on a third party service to generate the QR code, this plugin uses the PHPQRCode library by Dominik Dzienia, and stores the QR image on your website.
     17This plugin uses the Endroid QR-Code PHP library.
