mono italic won't print??

[dmurdoch]

Here's a strange bug on my Mac:

doit <- function() {
  text <- c("mono 1", "mono 2", "mono 3", "mono 4")
  plot(1:4, 1:4, type="n")
  text(2, 1:4, text, family="mono", font=1:4)
  dev.off()
}

agg_png("test.png")
doit()

This produces this plot:

The same thing happens with other agg_* devices, but not the standard devices, e.g.

png("test.png")
doit()

produces this:

This seems related to r-lib/systemfonts#105, however ragg is using textshaping so maybe not...

I can reproduce and will investigate

[thomasp85]

No, this is definitely related. Freetype is throwing the same 130 error when trying to load the glyph - however, AGG simply ignores the glyph in this case so nothing is plottet

[thomasp85]

This will get fixed with r-lib/systemfonts#105

I'll close here as this is a systemfonts issue (though it really is a FreeType/Courier issue)
