 P -- Loaded and on-disk path mismatch.

IMO, this comes from the fact that the image overflows vertically.

I've successfully produced a pdf by reducing the image height. For instance, out.height=450 has worked for me.

Is there any way to pass arguments to the chrome printer to not clip the images? given that the html does manage to keep them in the slides.

Thanks.

I don't think that the problem can be solved by passing some options to pagedown::chrome_print(): I get the same behavior when I print manually the pdf with Chrome depending on the options.

IMO, the culprit is this CSS rule that collides with remark's scaling algorithm. When the top padding is removed, the image is well printed.

Nice css sleuthing ! Thanks
