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($font->{'head'}, 'head');
# Print one glyph's data:
print ttfdump($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.)
