NAME
Font::TTF::Dumper - Debug dump of a font datastructure, avoiding
recursion on ' PARENT'
SYNOPSIS
use Font::TTF::Dumper;
# Print a table from the font structure:
print ttfdump($font->{$tag});
# Print font table with name
print ttfdump($font->{'head'}, 'head');
# Print font table with name and other options
print ttfdump($font->{'head'}, 'head', %opts);
# Print one glyph's data:
print ttfdump($font->{'loca'}->read->{'glyphs'}[$gid], "glyph_$gid");
DESCRIPTION
Font::TTF data structures are trees created from hashes and arrays.
When trying to figure out how the structures work, sometimes it is
helpful to use Data::Dumper on them. However, many of the object
structures have ' PARENT' links that refer back to the object's parent,
which means that Data::Dumper ends up dumping the whole font no matter
what.
The main purpose of this module is to invoke Data::Dumper with a filter
that skips over the ' PARENT' element of any hash.
To reduce output further, this module also skips over ' CACHE' elements
and any hash element whose value is a Font::TTF::Glyph or
Font::TTF::Font object. (Really should make this configurable.)
If $opts{'d'}, then set Deepcopy mode to minimize use of
crossreferencing.
