Can we set out-width and out-height for latex figures?

[shabbychef]

It seems that the options

#| out-width: "0.5\\textwidth"
#| out-height: "0.32\\textwidth"

have no effect on .pdf output: the figure is not half sized; when I save the intermediate .tex file, there are no "textwidth" in the doc, etc.
Is this expected? How should one set the output figure width in pdf output?

I noticed the same thing. This is a difference compare to using knitr in R Markdown.

out-width will be passed as width attributes. Example

![](test2_files/figure-pdf/unnamed-chunk-3-1.pdf){fig-pos='H' width=\\textwidth}

It seems pandoc does not support setting \textwidth passed in the width attributes. 🤔

Though you can use % units which Pandoc's deal with specially

#| out-width: "50%"
#| out-height: "32%"

\includegraphics[width=0.5\textwidth,height=0.32\textheight]{test2_files/figure-pdf/unnamed-chunk-3-1.pdf}

I think I'll open an issue about the latex string passed to width to see what we can do.
