NAME
Font::TTF::Hmtx - Horizontal Metrics
DESCRIPTION
Contains the advance width and left side bearing for each glyph. Given
the compressability of the data onto disk, this table uses information
from other tables, and thus must do part of its output during the
output of other tables
INSTANCE VARIABLES
The horizontal metrics are kept in two arrays by glyph id. The variable
names do not start with a space
advance
An array containing the advance width for each glyph
lsb An array containing the left side bearing for each glyph
METHODS
$t->read
Reads the horizontal metrics from the TTF file into memory
$t->numMetrics
Calculates again the number of long metrics required to store the
information here. Returns undef if the table has not been read.
$t->out($fh)
Writes the metrics to a TTF file. Assumes that the "hhea" has updated
the numHMetrics from here
$t->update
Updates the lsb values from the xMin from the each glyph
$t->out_xml($context, $depth)
Outputs the table in XML
BUGS
None known
