NAME

6       Font::TTF::Hmtx - Horizontal Metrics
7

DESCRIPTION

9       Contains the advance width and left side bearing for each glyph. Given
10       the compressability of the data onto disk, this table uses information
11       from other tables, and thus must do part of its output during the out‐
12       put of other tables
13

INSTANCE VARIABLES

15       The horizontal metrics are kept in two arrays by glyph id. The variable
16       names do not start with a space
17
18       advance
19           An array containing the advance width for each glyph
20
21       lsb An array containing the left side bearing for each glyph
22

METHODS

26       Reads the horizontal metrics from the TTF file into memory
27
28       $t->numMetrics
29
30       Calculates again the number of long metrics required to store the
31       information here. Returns undef if the table has not been read.
32
33       $t->out($fh)
34
35       Writes the metrics to a TTF file. Assumes that the "hhea" has updated
36       the numHMetrics from here
37
38       $t->update
39
40       Updates the lsb values from the xMin from the each glyph
