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
