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 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 purpose of this module is to do just one thing: 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.)
