mono fonts (was RE: [Rd] RE: [R] SAS or R software)
Ah, I'm using Exceed Hummingbird 7.1 as the X server.... It does have fixed width fonts, and it is happy with variable width fonts up to this extreme .... A little more fiddling shows that this succeds with a linux based X11 server, and that even plot(1,1) par(family="mono",cex=8) text(1,1,"foo") segfaults. I've tested values of cex. Anything above 2.1249 seems to segfault. -G> -----Original Message----- > From: Prof Brian Ripley [mailto:ripley@stats.ox.ac.uk] > Sent: Monday, December 20, 2004 4:39 PM > To: Warnes, Gregory R > Cc: Paul Murrell; R-Devel > Subject: mono fonts (was RE: [Rd] RE: [R] SAS or R software) > > > [Please update the subject line, folks!] > > We need to know the device in use here ... and only a few > support this > mechanism. > > If it is X11(), I suspect the problem is in what fonts are available, > since cex=8 is pretty extreme.

Anything above 2.1249 seems to segfault.The X11 device works pretty hard to find a font to use and if it really can't find anything it should throw an error, not segfault. Are you able to debug this and see where it is failing? (I'm using Xwin32 and for large font size requests that can't be satisfied I get the intended behaviour which is warnings that a smaller font is being substituted) Paul>>-----Original Message----- >>From: Prof Brian Ripley [mailto:ripley@stats.ox.ac.uk] >>Sent: Monday, December 20, 2004 4:39 PM >>To: Warnes, Gregory R >>Cc: Paul Murrell; R-Devel >>Subject: mono fonts (was RE: [Rd] RE: [R] SAS or R software) >> >> >>[Please update the subject line, folks!] >> >>We need to know the device in use here ... and only a few >>support this >>mechanism. >> >>If it is X11(), I suspect the problem is in what fonts are available, >>since cex=8 is pretty extreme.
