🎀 Font::TTF::Hmtx(3) — Horizontal Metrics 🎀

okay bestie, this is the User Contributed Perl Documentation page for Font::TTF::Hmtx(3) — yes, the horizontal metrics icon. let’s get into it 💅

✨ NAME ✨

Font::TTF::Hmtx — Horizontal Metrics

🌸 DESCRIPTION 🌸

It contains the advance width and the left side bearing for each glyph. Because of 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 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.

🔥 METHODS 🔥

⭐ $t->read

Reads the horizontal metrics from the TTF file into memory.

⭐ $t->numMetrics

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

⭐ $t->out($fh)

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

⭐ $t->update

Updates the lsb values from the xMin from the each glyph.

⭐ $t->out_xml($context, $depth)

Outputs the table in XML.

💀 BUGS 💀

None known. not me manifesting bugs, okay? 💀
