NAME

6       Font::TTF::Vmtx - Vertical Metrics
7

DESCRIPTION

9       Contains the advance height and top side bearing for each glyph. Given
10       the compressability of the data onto disk, this table uses information
11       from other tables, and thus must do part of its output during the
12       output of other tables
13

INSTANCE VARIABLES

15       The vertical metrics are kept in two arrays by glyph id. The variable
16       names do not start with a space

18       advance
19           An array containing the advance height for each glyph
20
21       top An array containing the top side bearing for each glyph
22

METHODS

24   $t->read
25       Reads the vertical metrics from the TTF file into memory
26
27   $t->out($fh)
