fig-dpi doesn't affect dpi in the revealjs format

[nilsreimer]

I love using Quarto to put together my slides for teaching statistics—but have one problem I can't figure out.

I use the revealjs format and include figures using the ggplot2 R package. For example, I might include the following code chunk:

#| echo: false
#| fig-width: 4.375
#| fig-dpi: 300
ggplot(data = NULL, aes(x = rnorm(10), y = rnorm(10))) +
  geom_point()

I find, however, that the figure in the generated .html presentation still has the default resolution (96 dpi). What am I doing wrong? How can I get a higher-resolution figure? I use RStudio on Windows 11 in case that is relevant.

Thank you in advance.

fig-dpi is not currently forwarded as a cell option. Try this:

---
format: revealjs
title: DPI test
fig-dpi: 300
---

```{r}
#| echo: false
#| fig-width: 4.375
library(ggplot2)
ggplot(data = NULL, aes(x = rnorm(10), y = rnorm(10))) +
  geom_point()
```

If I am not mistaken, one could use the knitr option for code cells, i.e., fig.dpi instead.
Although, it can easily get confusing.

Thank you! This solved my issue.
