Font::TTF::Dumper(3pm) User Contributed Perl Documentation Font::TTF::Dumper(3pm)NAME
Font::TTF::Dumper - Debug dump of a font datastructure, avoiding recursion on ' PARENT'
SYNOPSIS
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.)

Font::TTF::Glyf - The Glyf data table
DESCRIPTION
This is a stub table. The real data is held in the loca table. If you want to get a glyf look it up in the loca table as
"$f-"{'loca'}{'glyphs'}[$num]>. It won't be here!
The difference between reading this table as opposed to the loca table is that reading this table will cause updated glyphs to be written
out rather than just copying the glyph information from the input file. This causes font writing to be slower. So read the glyf as opposed
to the loca table if you want to change glyf data. Read the loca table only if you are just wanting to read the glyf information.
This class is used when writing the glyphs though.
METHODS
$t->read
Reads the "loca" table instead!
$t->out($fh)
Writes out all the glyphs in the parent's location table, calculating a new output location for each one.
$t->out_xml($context, $depth)
Outputs all the glyphs in the glyph table just where they are supposed to be output!
$t->XML_start($context, $tag, %attrs)
Pass control to glyphs as they occur
$t->XML_end($context, $tag, %attrs)
Collect up glyphs and put them into the loca table
