NAME

       Font::TTF::Vmtx - Vertical Metrics

DESCRIPTION

       Contains the advance height and top 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 vertical metrics are kept in two arrays by glyph id. The variable names do not start
       with a space

       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 TTF file into memory

   $t->out($fh)
       Writes the metrics to a TTF file. Assumes that the "vhea" has updated the numVMetrics from
       here
