Font::TTF::Hmtx(3) User Contributed Perl Documentation Font::TTF::Hmtx(3)

Font::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

Reads the horizontal metrics from the TTF file into memory

Calculates again the number of long metrics required to store the information here. Returns undef if the table has not been read.

Writes the metrics to a TTF file. Assumes that the "hhea" has updated the numHMetrics from here

Updates the lsb values from the xMin from the each glyph

Outputs the table in XML
