italic font on cairo devices in R 3.4
Hi Ilia, I'm running Arch Linux, R 3.4.0. Here's my test.pdf from your minimal example: https://ptpb.pw/HxsA.pdf It doesn't look pixelated to me... Here's a post that I wrote when I solved my last font problem in R, almost 2 years ago: https://stackoverflow.com/a/40940331/5087283 I had to install some Microsoft font packages, which is sad, because there are some perfectly good free fonts that R could be using instead. It could be considered a bug that R requires Microsoft fonts, at least by default. However, does this even fix your problem? I.e. if you install the corresponding Debian Microsoft font packages, does the text appear anti-aliased? Frederick

Hi all,
I have the following problem: Since R 3.4.0, italic fonts rendered on Cairo
devices appear pixelated. Here's a minimal example:
cairo_pdf('test.pdf')
plot(1:10, ylab=expression(italic(test)))
dev.off()
The same problem occurs with bolditalic, but not bold. I am using Debian
Stretch. Several friends tried the same on their machines, another Debian
machine has the same problem. On MacOSX the output was not pixelated, but it
wasn't italic either. Ubuntu 16.04.2 xenial works fine. My impression is
that R somehow can't find the proper font to use and falls back to something
weird. Ideas?
Note that I'm not subscribed to the list, so please CC me in replies.
Cheers, Ilia
