Horizontal Metrics

INSTANCE VARIABLES

advance
An array containing the advance width for each glyph

lsb
An array containing the left side bearing for each glyph


METHODS

$t->numMetrics

Calculates again the number of long metrics required to store the information here. Returns undef if the table has not been read.
