To embed TrueType fonts (.TTF) files, you need to extract the font metrics and 
build the required tables using the ttf2ufm utility. 

TTF2UFM is a modified version of Mark Heath's TTF 2 PT1 converter 
(http://ttf2pt1.sourceforge.net/) by Steven Wittens <steven@acko.net> 
(http://www.acko.net/blog/ufpdf).

ttf2ufm, is not bundled with the Moodle distribution, but it is available with
the standard TCPDF distribution (http://tcpdf.sourceforge.net/):

 - Source code is avaialable in in /ttf2ufm-src. 
 - The /fonts/ttf2ufm folder contains a compiled Windows binary. 

TTF 2 UFM is identical to TTF 2 PT1 except that it also generates a .ufm file 
for usage with makefontuni.php.


Setting up a Truetype font for usage with TCPDF:
  1) Generate the font's .ufm metrics file by processing it with the provided 
     ttf2ufm program (modified ttf2pt1). For example:
     $ ttf2ufm -a -F myfont.ttf
  2) Run makefontuni.php with the .ttf and .ufm filenames as argument:
     $ php -q makefontuni.php myfont.ttf myfont.ufm
  3) Copy the resulting .php, .z and .ctg.z file to the TCPDF font directory.
