Re: [R] pdf font embedding --- again

Hi

I think there are two problems:

(i) You are specifying the font incorrectly. Try ...

# You might need to specify full paths to these afmfiles <- c("lbr.afm", "lbd.afm", "lbi.afm", "lbdi.afm", "lbms.afm"); # Set up the mapping for "lucida" font family postscriptFonts(lucida=postscriptFont("Lucida", metrics=afmfiles)) # Specify that the "lucida" font is to be used postscript(file="test.ps", family="lucida"); l<- 40:80;
plot(l,l,pch=l);
dev.off();

Should work for pdf() too.

This should put a reference to the appropriate font in the PostScript or   PDF file that R creates.

(ii) R does not embed font information. But you can, for example, use ghostscript to do it, as long as you tell ghostscript about the font too. You might have to set up a file 'FontMap' which looks something like ...

/Lucida (PATH_TO/lb___.pfb);

... (assuming that lb___.pfb is the name of the .pfb file for the Lucida font). Then try something like (NOTE that you have to specify GS_FONTPATH to tell ghostscript where your FontMap file is) ...

GS_FONTPATH=PATH_TO_FontMap gs -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sPAPERSIZE=a4 -sOutputFile=testembed.pdf test.pdf

This should give you a file with the font info embedded and then you should be able to include that in a LaTeX document.

Paul

p.s. Thanks for the segfault report. I will look at why that is happening.
