=head1 NAME
PDF::API3::Compat::API2::Basic::TTF::PCLT - PCLT TrueType font table
=head1 DESCRIPTION
The PCLT table holds various pieces HP-PCL specific information. Information
here is generally not used by other software, except for the xHeight and
CapHeight which are stored here (if the table exists in a font).
=head1 INSTANCE VARIABLES
Only from table and the standard:
version
FontNumber
Pitch
xHeight
Style
TypeFamily
CapHeight
SymbolSet
Typeface
CharacterComplement
FileName
StrokeWeight
WidthType
SerifStyle
Notice that C<Typeface>, C<CharacterComplement> and C<FileName> return arrays
of unsigned characters of the appropriate length

=head2 $t->read
Reads the table into memory thanks to some utility functions
=cut

$self;
}
=head2 $t->out($fh)
Writes the table to a file either from memory or by copying.
=cut
