Inproper/misaligned PDF export

[ZimengXiong]

PDF is exported with too much right margin, distorting the slide.

I tried this on mac and couldn't reproduce it. Are you using presenterm 0.15.1? It may help to debug if you can do the following:

mkdir /tmp/output
presenterm -e examples/demo.md -c ~/.config/presenterm/config.yaml --export-temporary-path /tmp/output

Then attach the html and css files in /tmp/output.

I did a reinstall of presenterm 0.15.1 and cloned the demo repository again:

I realized I had a config set up in config.yaml:

       │ File: /Users/zimengx/.config/presenterm/config.yaml.bak
───────┼─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
   1   │ export:
   2   │   dimensions:
   3   │     columns: 120
   4   │     rows: 33
───────┴────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

So I ran again without the config, and the same issue still occurs. I have attached files without the config below

Note that the config file did not exist (-c flag path), so I touched an empty file at ~/.config/presenterm/config.yaml

index.html
styles.css
demo.pdf

[mfontanini]

I don't see anything strange, your output is the same as mine so I think this is something env specific that weasyprint/whatever browser context it uses to do the rendering is behaving differently. I wonder if running presenterm in docker would help. It's not ideal but it's may do it. You can do something like:

# mount your config file + the examples directory
docker run --rm -ti -v ~/.config/presenterm/config.yaml:/tmp/config.yaml -v ./examples:/tmp/examples ubuntu:latest

Then inside docker run:

apt update && apt install -y weasyprint wget
cd /tmp
wget https://github.com/mfontanini/presenterm/releases/download/v0.15.1/presenterm-0.15.1-x86_64-unknown-linux-musl.tar.gz
tar xvzf presenterm-0.15.1-x86_64-unknown-linux-musl.tar.gz
presenterm-0.15.1/presenterm -e /tmp/examples/demo.md -c /tmp/config.yaml

If this works, I could add a docker image that gets generated along with the release.

[ZimengXiong]

Yup, within the docker container it seems to work as expected. I will try to see what is irregular about my setup, I am running standard Chrome as my default browser.
