QR-Codes from latex package {qrcode} are generated but are not clickable links

Description

I'm using latex and the qrcode package to generate qr-codes for my pdf outputs. It's very simple and just needs the following, which creates a qr-code and also makes the image of the code a clickable link to the same destination as the code:

\qrcode[hyperlink,height=0.5in]{http://www.ctan.org}

Creating the qr-code works fine, but the image is not a clickable link. This works in other documents but somehow quarto seems to remove/not add the link to the image.

Does anyone have an idea on how to fix this?

Could you share a small self-contained "working" (reproducible) example to work with, i.e., a complete Quarto document or a Git repository? Thanks.

Meanwhile, you can use keep-tex: true to investigate the LaTeX file produced by Quarto.

You can share a Quarto document using the following syntax, i.e., using more backticks than you have in your document (usually four ````).

````qmd
---
title: "Reproducible Quarto Document"
format: html
---

This is a reproducible Quarto document using `format: html`.
It is written in Markdown and contains embedded R code.
When you run the code, it will produce a plot.

```{r}
plot(cars)
```

The end.
````

Yes, this is a working example:

---
title: "qrTest"
format:
  pdf:
    include-in-header:
      - text: |
          \usepackage{qrcode}
editor: visual
---

This is ***markdown*** content, and here we switch to latex to generate the qr-code:

\qrcode[hyperlink,height=0.5in]{http://www.ctan.org}

This is ***markdown*** again.

I would say, it is likely a conflict with one of the LaTeX packages used in the template (from Pandoc).

I suggest you investigate this using keep-tex: true and moving \usepackage{qrcode} in the frontmatter/header of the tex file and rendering using a LaTeX engine.
