Truetype and Opentype font in pdf device

Thanks for the reply. I got that there is no general way to generate PDF with ttf or otf fonts. Thanks, it's enough. Also, cario_pdf is useful (I'm using OSX). But I found it cannot correctly(?) work with CJK.
The Mac OS X (why do Mac users not know the name of their OS?) implementation of cairographics is rather limited, because of font issues. CJK works fine (I am told by Chinese and Japanese users) with cairographics on other OSes.
I will play with them some more.

Deal all, I want to know if truetype or opentype fonts are available in pdf device (i.e., pdf() or dev.copy2pdf()), and if so, how to do it?
They are not in general available in PDF, the language. ?The cairo-based device embed individual glyph information from such fonts (perhaps as vectors and perhaps as bitmaps).
Now I can do as followings:
1. convert ttf to afm using ttf2afm, e.g.: $ ttf2afm Impact.ttf >
Impact.afm
2. put the afm file in $R_HOME/library/grDevices/afm
3. register a new type1 font: pdfFonts(Impact=Type1Font("Impact",
rep("Impact.afm", 4), encoding = "TeXtext.enc"))
4. specify the fontfamily in gpar: grid.text('hello grid world',
gp=gpar(fontfamily="Impact"))
but obviously, it is better if truetype or opentype fonts are directly
available without conversion to type1 font.
But you would still need to make the font available to your PDF viewer/printer, and in general that does need coversion (to a font type supported in PDF or to bitmaps/vectors).
Also, I found that Cairo package can handle truetype or opnetype font. However, the package seems not to support fontfamily, hence I cannot use it through gpar.
Have you not considered the built-in and fully featured cairo_pdf device? ?(Not Windows, but you didn't tell us your OS.)
Does anyone know about this topic? Thank you in advance. -- Kohske Takahashi <takahashi.kohske at gmail.com> Research Center for Advanced Science and Technology, The University of ?Tokyo, Japan. http://www.fennel.rcast.u-tokyo.ac.jp/profilee_ktakahashi.html
