I'm using cairo_pdf() to generate a plot in R with nice fonts. It works fine if the font family I specify has basic weights named sensibly, e.g. "Arial" contains Arial Regular, Arial Bold, Arial Italic, Arial Bold Italic.
But is there a way to arbitrarily set the font for a given style? For example, in Hoefler Text I have Hoefler Text Black not Bold. Can I get cairo_pdf to use this weight for bold text?
I'm probably using a different OS than you but I'm wondering if there's a chance that this will succeed on a Linux box, although it doesn't succeed on my Mac. The font styles were determined with Mac-specific application, FontBook.app, but I imagine that you have fontforge or similar access to a way to determine needed names of styles.:
Cairo::CairoFonts( # for some reason I seem to need the `pkgname::` format
regular="Hoefler Text:style=Regular",
bold="Hoefler Text:style=Black",
italic="Hoefler Text:style=Italic",
bolditalic="Hoefler Text:style=Black Italic",
symbol="Symbol"
)
Cairo::CairoFontMatch("Hoefler Text:style=Black",verbose=TRUE)
cairo_pdf("test_bold.pdf", family="Hoefler Text")
plot(1,1, main=bquote(bold(test~fl~ligature)) )
dev.off()
The output on my machine appears to be in the 'Hoefler Text' family, but the style does not appear to be any different that the non-bold call. I thinking a Linux machine might have better luck.
Update: I used one of the "online font converters" found on an SO search to extract the 'Hoefler Text.ttc' (a TrueType collection) fonts into its components. I moved them into the /Library/Fonts/ directory. I looked at the output from Cairo::CairoFontMatch("HoeflerText:style=Black",verbose=TRUE) and saw that there it was seeing the ttc file so I moved the original ttc file to a non-Font directory and restarted R.
Now when I run:
cairo_pdf("test_bold.pdf", family="HoeflerText")
plot(1,1, main=bquote(bold(test~fl~ligature)) ); dev.off()
... and view in my PDF viewer I see a bold font as title. I am not sure if this is actually a result of a) remapping the fonts by R or if b) the viewer is now doing the proper lookup and had not been given the correct name by the cairo_pdf device. At any rate, I am now able to do the correct lookup:
> Cairo::CairoFontMatch("HoeflerText:style=Black",verbose=TRUE)

names(X11Fonts())does not bring up 'Hoefler Text' on my machine, but it's certainly possible that your machine is different. Why don't you review?cairo_pdfand?X11Fontsand then provide sufficient specifics so we can offer advice? I will hold off voting to close as "unclear" but only for a few hours. After that I will both downvote and vote to close. – IRTFMCairoFontsdoes for example. – jkeirstead
