Hello,
Here is a reproducible example of the issue
curl --output background.jpg -L 'https://unsplash.com/photos/8OyKWQgBsKQ/download?force=true&w=1920'
echo "# Slide {data-background-image='background.jpg'}" > slide.md
echo "" >> slide.md
echo "Content" >> slide.md
# Not self contained
pandoc -t revealjs -s -o slide.html --metadata title="test" slide.md
# Self contained
pandoc -t revealjs --self-contained -o slide-self-contained.html --metadata title="test" slide.md
When using self-contained, the background image is no more working. Pandoc
encodes to data: but it seems reveal.js does not know how to handle it. It
split the encoded data: in two url component.
It seems like a change in reveal 4 as using the same slide.md file with
different version seems to break.
What I tried:
- Pandoc 2.9.2.1 : last one compatible with reveal.js 3 I believe
pandoc.exe -t revealjs --self-contained -o slide-self-contained.html --metadata title="test" -V revealjs-url=https://unpkg.com/reveal.js@3/ slide.md
Works as expected
- Pandoc 2.10: First to use reveal.js 4
pandoc.exe -t revealjs --self-contained -o slide-self-contained.html --metadata title="test" -V revealjs-url=https://unpkg.com/reveal.js@4/ slide.md
So it seems that something broke when upgrading.
Is this a known issue ?
Should I open an issue in Pandoc to track ? I believe this could be
something in reveal.js not handling correctly encoded data: field.
MANUAL still says (
https://pandoc.org/MANUAL.html#background-in-reveal.js-and-beamer)
Background images can be added to self-contained reveal.js slideshows and
to beamer slideshows.
But maybe self-contained and revealjs does not work well.
Thank you
