The output for QRCode is displayed in view with $report->run()->render(); is output as a canvas image.

Is there a way to request output in a file format that can be saved?

Or second option, is there a way to capture the canvas image so that it can be saved?

Thanks.

I am using the script straight out of your documentation and example including "format" => "png", as you described.

Output comes as data:image/png;base64, with a long string of characters that has to be captured in javascript because it is contained in a windows DOM widget, then stripped of the prefix and saved, which I never completely got. In short, if you want to save the image in it's current format, it is a lot of work to convert to a saved file.

Here is the output straight off the PNG on your example page:

I am looking for an option to write directly to a file such as qrc-my-link.png then I can save the file on my server, and call it from database whenever needed.

Is standard practice to simply output for viewing every time it is called? I am giving my customers the option to choose one of three sizes to use in their advertising.
