LaTeX, as far as I know, does not support TrueType fonts. TrueType
fonts are something which is more specific to Windows and MacOS than
you think because these fonts are not necessarily available in Linux
systems due to licensing and patent encumberement reasons (for more
info, see: http://en.wikipedia.org/wiki/TrueType).
As far as I know, correct me if I'm wrong, TrueType fonts look better
on screen but the Postscript Type 3 fonts used by LaTeX should work
better in printed output. Maybe an in-between option would be to use
Postscript Type 1 fonts?
Using TrueType fonts in LaTeX is more than just installing the fonts
in the system that compiles the PDF, LaTeX needs information related
to the fonts in order to include them when generating a Postscript
version of the document. If we were to do this that would mean that
the system building the PDFs would have to be tailored-made, since
this cannot be implemented in the (automated) building system I
introduced in SNV. You have a (good) overview of LaTeX font
processing, if interested in
http://www-h.eng.cam.ac.uk/help/tpl/textprocessing/fonts.html.
I will try to investigate (using these tips:
http://www.radamir.com/tex/ttf-tex.htm) how to make the PDFs with
TrueType fonts. I remember (and indeed, found in my mailbox) that we
had this same conversation almost two years ago when I provided PDF
versions of the books. Unfortunately, I have not been able to pursue
this further, let's see if this summer...
Upon reviewing, I found this source:
http://dsanta.users.ch/resources/type1.html, describes the issues with
LaTeX and Truetype fonts. An alternative might be to generate the PDF
versions from the Postscript version in a Windows system. Maybe Ingo
can provide you with the PostScript versions and you can convert them
in your system with Adobe Distiller to see how it turns out.
It looks to me that we several options right now regarding fonts in the PDF:
1- Do nothing, use the fonts used by LaTex / pdf2ps and see if users
complain about them
2- Change the building system so that it use Type 1 Postscript fonts
instead of Type 2
3- Generate the PDFs using TrueType fonts on Linux, which might mean
having a dedicated setup (not easy to replicate) for building PDFs
4- Generate the PDFs usign TrueType fonts with a combination of Linux
(to generate the Postscript version) and Windows (to generate the PDF
versions using Adobe's Distiller?).
5- Do nothing, publish both Postscript and PDF versions at the site so
that users have an option (they could do PS->PDF conversion if they
wanted to themselves)
Right now, I would favor doing the last option so as to not delay PDF
publication, which is a very common request from our users. Opinions?
