G'day all,
I am using Cairo to produce output graphics (mainly png), but don't
seem to be able to figure out how to stop the text being rendered in
italics.
This is a known issue in how freetype+fontconfig cannot agree on the
right traits in some cases if font suitcases are involved on some
versions of OS X. You can force the default fonts to specific names
using CairoFonts, e.g. the following is known to work:
CairoFonts
("Arial:style
=Regular","Arial:style=Bold","Arial:style=Italic","Helvetica","Symbol")
If that doesn't help, make sure you have Arial enabled or use a
different font.
Cheers,

I am using 10.6.2, and R version 2.10.1 Patched (2010-02-01 r51089).
Using this produces the output as I anticipated (with upright text)
png('outputs/reports_by_province2.png')
barplot(outbreaks.summary$Provinces,names.arg=outbreaks.summary
$Year, ylab='Number of provinces reporting outbreaks', cex.axis=1,
cex.names=1) -> tmp
Using this produces a nicer image (the transparent background is
important), but the text is all italicised
Cairo(950,450, 'outputs/reports_by_province.png')
barplot(outbreaks.summary$Provinces,names.arg=outbreaks.summary
$Year, ylab='Number of provinces reporting outbreaks', cex.axis=1.2,
cex.names=1.2) -> tmp
I can change the family, ie :
par('family')
[1] "serif"
but Cairo doesn't seem to respect it (I'm actually wanting Helvetica
so it doesn't matter), but I can't fix the font (and I note from the
docs:
fonts see pdf, ignored, Cairo automatically detects and embeds fonts
)
So I'm wondering if it is just my installation, a known issue or
I've missed the workaround (using CairoFonts hasn't changed it).
Are you sure? Please try the above.
cheers
Beb
