Vertical metrics
Overview
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
