[cairo] Newbie questions on fonts

I have just started using cairo. I have followed the thread
in the cairo archives of late December 2006 on "Problems
compiling Cairo..doesn't detect fontconfig/freetype
installation" and, in particular, I installed into a
private directory (say /home/myhome/cairo) on a Mac OS X machine:
I have put /home/myhome/cairo/lib on my DYLD_LIBRARY_PATH and
/home/myhome/cairo/lib/pkgconfig on my PKG_CONFIG_PATH as well as
putting /home/myhome/cairo/bin on my PATH.
1.) Just what are the "toy" fonts? What font database is
being used for those? When I execute:
cairo_select_font_face (cr, "serif",
cairo_show_text (cr, "Text");
I do not get an Italic font, but just the normal font.
2.) Installing fontconfig creates an /etc/fonts directory (I wish
the documentation of fontconfig was specific about that) and
lists some font directories in the fonts.conf file in
that directory. There are some fonts in /Library/fonts
that I would like to access and the directory
/Library/fonts is not listed in fonts.conf. The directive
in fonts.conf says not to edit that file but put local
changes in a 'local.conf' file which I did by inserting:
in an xml file created using the fonts.conf file as a template.
I was hoping that this would then give me access to the
fonts in /Library/Fonts using the font name in a
cairo_select_font_face call with the font name as the second
argument. But a subsequent call to cairo_show_text
just gives me the default serif font.
Should the above work? Is my assumption correct that cairo
is looking at the files in /etc/fonts to find its fonts?
Since the above did not work, I put the line
in fonts.conf, but that did not work either.
3.) Since the above did not work, I tried accessing the fonts
directly using the calls:
error = FT_Init_FreeType( &library );
error = FT_New_Face( library,
"/Library/Fonts/ArialHBBold.ttf", 0, &face );
font_face = cairo_ft_font_face_create_for_ft_face(face,0);
I did not get any error returns, but a show_text call just
Any help will be appreciated.
