6 Font::TTF::Dumper - Debug dump of a font datastructure, avoiding
7 recursion on ' PARENT'

10 Font::TTF::Dumper;
11
12 # Print a table from the font structure:
13 print ttfdump($font->{$tag});
14
15 # Print font table with name
16 print ttfdump($font->{'head'}, 'head');
17
18 # Print one glyph's data:
19 print ttfdump($font->{'loca'}->read->{'glyphs'}[$gid], "glyph_$gid");

22 Font::TTF data structures are trees created from hashes and arrays.
23 When trying to figure out how the structures work, sometimes it is
24 helpful to use Data::Dumper on them. However, many of the object
25 structures have ' PARENT' links that refer back to the object's parent,
26 which means that Data::Dumper ends up dumping the whole font no matter
27 what.
28
29 The purpose of this module is to do just one thing: invoke Data::Dumper
30 with a filter that skips over the ' PARENT' element of any hash.
31
32 To reduce output further, this module also skips over ' CACHE' elements
33 and any hash element whose value is a Font::TTF::Glyph or
34 Font::TTF::Font object. (Really should make this configurable.)
