PDF::API2::TTF::Hmtx - Horizontal Metrics
Contains the advance width and left 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
The horizontal metrics are kept in two arrays by glyph id. The variable names do not start with a space
advance | |
An array containing the advance width for each glyph | |
lsb | |
An array containing the left side bearing for each glyph |
