Hello,

I have  idea to generate QR codes from http links, by script.

Links will be wriiten as a text lines in a txt or doc file.

Help me please how to start coding the script. Where in API should i look for the methods and properties ? In which suite the QRcode engines egsist?

The QRcode itself is EPS, placed ino a frame, how to first generate the QR by javascript ?

My favorite documentation I always use is here:

Thank you for any suggestions

Marcin

No need for external libraries.

You'd create or reuse an EPS page item, then invoke its create ... QRCode () method matching your type, e.g.

https://www.indesignjs.de/extendscriptAPI/indesign14/#EPS.html#d1e240502__d1e242534

The document has the same set of create methods, the QR code is then loaded into the place gun for manual place.

That's as far I remember it from some AppleScript experiments.

No time to try, but as it is a method of all page items, would you not just invoke it on an empty rectangle?

And now I've tried it. It is indeed very easy: if you have a handle to an existing rectangle, you can immediately call its own createHyperlinkQRCode method, and the only argument it needs is the URL itself. (Unless you want to change the color etc., but see grefel's documentation for that.)

A one-line test shows this creates the exact same QR code as when done through the interface. In the image below, the left is a QR code generated with the menu option "Generate QR Code", type Web Link, and the right a blank rectangle that, when selected, gets filled with the same URL using the magic line

app.selection[0].createHyperlinkQRCode ("https://www.indesignjs.de/extendscriptAPI/indesign14/#EPS.html#d1e240502__d1e242534");
