PDF::API2::Basic::TTF::Vmtx(3)
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
BUGS
None known
