advance

An array containing the advance height for each glyph

top

An array containing the top side bearing for each glyph

METHODS

$t->read

Reads the vertical metrics from the file into memory

$t->out($fh)

Writes the metrics to a file. Assumes that the "vhea" has updated the numVMetrics from here

None known
