Font::TTFMetrics encapsulates the font metrics of a true type font
file. A true type font file contains several tables which need to
be parsed before any useful information could be gathered about
the font. There is the excellent module for parsing TTF font in
CPAN by Martin Hosken, Font::TTF. But in my opinion the use of
Font::TTF requires intimate knowledge of TTF font format. This
module was written to support the use of TTF in Pastel 2D graphics
library in Perl. Three factors prompted me to write this module:
first, I required a fast module to access TTF file. Second, all
the access required was read-only. Last, I wanted a user friendly,
higher level API to access TTF file.
