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
