I would like to cross-reference an image which I include with the markdown ![caption with spaces](path/to/image.png)
syntax.
I would like to be able to cross-reference this image as \@ref(fig:caption-with-spaces)
.
I am using bookdown::pdf_document2
.
Is this possible?

.If you'd like a keep everything in pure Markdown, but don't want to add identifiers manually, you can use a pandoc Lua filter:
Use by adding a
pandoc_args
parameter to your output settings:
