Making a single page landscape in a portrait document

[newzealandpaul]

I am authoring a PDF report with Quarto (papersize: a4, documentclass: article) and would like to know the best way to make a single page (with a mermaid diagram) portrait.

I am currently archiving it with

\newpage
\KOMAoptions{paper=landscape,pagesize}
```{mermaid}
...
```
\newpage
\KOMAoptions{paper=portrait,pagesize}

But this has two problems.

The first is that I lose page numbers on the landscape page.

The second problem is that it removes/overwrites the YAML header's geometry settings for the entire document.

I had to resort to adding the following in my header.tex

\usepackage[top=20mm,left=30mm,heightrounded ]{geometry}

Is there a better way of making a single page landscape in a portrait article? Or is this something I should make a feature request for.

I don't have any first hand experience with this though a couple of ideas:

1. The geometry package does support \newgeometry and \restoregeometry commands which could allow you to alter page geometric for a single page and then restore the old geometry.

2. You could experiment with packages like pdflscape package, which creates an environment that emits landscape pages... (https://ctan.math.washington.edu/tex-archive/macros/latex/contrib/pdflscape/pdflscape.pdf)

I just installed the quarto pre-release 1.6.23 and landscape come out-of-the-box, see: #10581,
else you can use the extension from which it originates edvinsyk/quarto-landscape]
