How can I export a QR code image with additional text below it?

I have an application that needs to support QR codes and I am analysing different solutions. Since I am already using kendo in the application I though I should test it. However when I tried with an example I saw that the code generated is not the same as the other QR code generators out there on the internet. All that I tested resulted in the same image, however the telerik resulted in a different image.

What QR code does it generate?

the text I used was "ABC123456789" on

https://racoindustries.com/barcodegenerator/2d/qr-code/

https://www.qrstuff.com/

https://ro.qr-code-generator.com/

https://www.the-qrcode-generator.com/

and all generated the same image but the https://demos.telerik.com/aspnet-core/qrcode/api generated a different image.

Is there a configuration that will generate the same code like the others code generators

High

we would like to add qr codes to our information boards to link to additional language versions of the information. Now it would be nice if we could add a text to the pdf exported from the qr code widget to indicate the language it links to.

Is there a way to inject a line of text e.g. below the qr code?

Regards

Alex

Hello

I'm working with the KendoQRCode Widget that is working fine! I'm also using the exportPDF/SVG/Image functions that all do a great job! 

Now I would like to send several created QRCodes (defined in KendoQRCode Widgets) to a single PDF file, so the user can print them all by one PDF file (see attachment). I don't know if that is possible at all so I tried several things. The closest I came to do that:

...
var qrCode = $("#qrcode").getKendoQRCode(); // Existing QRCode Widget
var draw = kendo.drawing;
 var root = new draw.Group();
var code = qrCode.exportSVG({ paperSize: "A4", landscape: false }).done(function(data) {
  root.append(data);
});
 
draw.exportPDF(root, { paperSize: "A4", landscape: true }).done(function(data) {
    kendo.saveAs({
    dataURI: data,
    fileName: "qrcodes.pdf"
  });
 });
..

The exportImage function does not throw an error but the QRCode is not in the generated PDF file. Using the function exportSVG throws an error: "TypeError: e.transform is not a function. (In 'e.transform()', 'e.transform' is undefined)".

So I wonder how do I send several QRCodes coming from the KendoQRCode Widget(s) into a single PDF file (if possible)? The KendoQRCode Widgets are all displayed in the page and therefore programmatically accessible.

Regards

It is possible to generate QRCode from server side using Kendo.Mvc.UI.QRCode?
I need to generate the QRCode for a web service that will be called from a desktop application.

I have built a small application using qrcode generation.

I have followed the examples, that are all great but miss only one thing:

All of them uses kendo.all.min.js as inclusion, and of course this is not a good choice for a web application because of performance issues.

I would like to have a list of the single javascript files I need for each widget, without the need to include kendo.all.js.

Is it possible to have a single file list for qrcode?

Simply using kendo.dataviz.qrcode.min.js is not enough and code is not generated.

Kind regards

Hi there,

Is IE 8 supported by the QR Code control? We're currently using scripts from version 2013.2.918 and we get this warning:

 Warning: KendoUI DataViz cannot render. Possible causes:
- The browser does not support SVG, VML and Canvas. User agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)
- The kendo.dataviz.(svg|vml|canvas).js scripts are not loaded 

Followed by an error in our qr code min file:
SCRIPT5007: Unable to set property 'children' of undefined or null reference 

Just wanted to confirm if this is expected based on the version we're using. IE 9 and up works just fine. Thanks.
