NAMEFont::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");
DESCRIPTIONFont::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.
