pdf font embedding --- again

Hi Paul:

I very much appreciate your spending the time to help me here, and I 
hope we will get a nice how-to document from this for other 
novices---or at least a google-able record in the r-help archive.

* The following is working R code to embed fonts, such as the lucida 
font family:

  afmfiles <- c("/usr/share/texmf/fonts/afm/yandy/lubright/lbr.afm",
              "/usr/share/texmf/fonts/afm/yandy/lubright/lbd.afm",
              "/usr/share/texmf/fonts/afm/yandy/lubright/lbi.afm",
              "/usr/share/texmf/fonts/afm/yandy/lubright/lbdi.afm",
              "/usr/share/texmf/fonts/afm/yandy/lumath/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="lu1.ps", fonts="lucida");
  l<- 40:80;

  plot(l,l,pch=l);
  dev.off();

* The resulting file lu1.ps knows about Lucida fonts, e.g.,

$ grep LucidaBright-Demi lu1.ps
%%+ font LucidaBright-Demi
%%+ font LucidaBright-DemiItalic
%%IncludeResource: font LucidaBright-Demi
/LucidaBright-Demi findfont
%%IncludeResource: font LucidaBright-DemiItalic
/LucidaBright-DemiItalic findfont

but is also still includes the Helvetica font family, even though my 
intent is to get rid of them.


* In the same local directory, I have a Fontmap file (note 
capitalization; thank strace!), which is

/LucidaBright (/usr/local/share/texmf/fonts/type1/yandy/lbr.pfb);
/LucidaBright-Demi (/usr/local/share/texmf/fonts/type1/yandy/lbd.pfb);
/LucidaBright-Italic (/usr/local/share/texmf/fonts/type1/yandy/lbi.pfb);
/LucidaBright-DemiItalic 
(/usr/local/share/texmf/fonts/type1/yandy/lbdi.pfb);
/LucidaNewMath-Symbol 
(/usr/local/share/texmf/fonts/type1/yandy/lbms.pfb);


* I can now execute ghostscript,

$ gs   -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sPAPERSIZE=a4 
-sOutputFile=testembed.pdf lu1.ps

which seems to indicate that the Fontmap file was found.  (Adding a 
"-GS_FONTPATH=." to point to the local directory is not necessary.)

* Alas, the output still does not have my Lucida fonts:

$ pdffonts testembed.pdf

name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
Helvetica                            Type 1C      yes no  no      10  0


Also, looking at either lu1.ps or testembed.pdf with previewers shows 
that I am still using Helvetica fonts, not Lucida fonts.  so something 
is still missing somewhere.  (I also tried creating a pdf file directly 
under R, and though it gives me no error, and although the resulting 
pdf file claims to reference both helvetica and lucida fonts [and 
others], upon viewing, I can see that there are only helvetica fonts 
visible; no lucida fonts.)

further help and advice would still be appreciated.

Regards,

/iaw

  Right, the fonts are referred to in the PostScript or PDF file, but no 
font information is embedded. Now we move to the second problem I 
mentioned, embedding the fonts. Can you try using ghostscript? (see my 
first post)
