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 out‐
12       put of other tables
13

INSTANCE VARIABLES

16       names do not start with a space

19           An array containing the advance height for each glyph
20
