To embed TrueType fonts (.TTF) files, you need to extract the font metrics and 

build the required tables using the provided utility (/fonts/ttf2ufm). 

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 included 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 or makefontuni.rb.

Setting up a Truetype font for usage with UFPDF:

  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_ruby.php with the .ttf and .ufm filenames as argument:

      $ php -q makefontuni_ruby.php myfont.ttf myfont.ufm

  3) Copy the resulting .rb, .z and .ctg.z file to the TCPDF font directory.

  4) Rename php font files variations for bold and italic using the following schema:

    	[basic-font-name]b.rb for bold variation

    	[basic-font-name]i.rb for oblique variation

    	[basic-font-name]bi.rb for bold oblique variation

  5) Rename the name of the font in the first line of each .rb file:

      TCPDFFontDescriptor.define('dtlargotitalic') do |font|

     becomes:

      TCPDFFontDescriptor.define('dtlargoti') do |font|
