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
2a) Run makefontuni.php with the .ttf and .ufm filenames as argument:
$ php -q makefontuni.php myfont.ttf myfont.ufm
2b) or run makefontuni.rb with the .ttf and .ufm filenames as argument:
$ php -q makefontuni.rb 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
