Font::TTF::Hmtx - Horizontal Metrics


NAME

Font::TTF::Hmtx - Horizontal Metrics


DESCRIPTION

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


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

$t->out($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
