PDF::API2::Resource::Font::CoreFont - Module for using the 14 PDF built-in Fonts.
=head1 SYNOPSIS
#
use PDF::API2;
#
$pdf = PDF::API2->new;
$cft = $pdf->corefont('Times-Roman');
#
=head1 METHODS
=over
=item $font = PDF::API2::Resource::Font::CoreFont->new $pdf, $fontname, %options
Returns a corefont object.
=cut
=pod
Valid %options are:
I<-encode>
... changes the encoding of the font from its default.
See I<perl's Encode> for the supported values.
I<-pdfname> ... changes the reference-name of the font from its default.
The reference-name is normally generated automatically and can be
retrived via $pdfname=$font->name.
