NAME

6       Font::TTF::Hdmx - Horizontal device metrics
7

DESCRIPTION

9       The table consists of an hash of device metric tables indexed by the
10       ppem for that subtable. Each subtable consists of an array of advance
11       widths in pixels for each glyph at that ppem (horizontally).
12

INSTANCE VARIABLES

14       Individual metrics are accessed using the following referencing:
15
16           $f->{'hdmx'}{$ppem}[$glyph_num]
17
18       In addition there is one instance variable:
19
20       Num Number of device tables.
21
22   METHODS
23   $t->read
24       Reads the table into data structures
25
26   $t->out($fh)
27       Outputs the device metrics for this font
28
29   $t->minsize()
30       Returns the minimum size this table can be. If it is smaller than this,
31       then the table must be bad and should be deleted or whatever.
32
33   $t->tables_do(&func)
34       For each subtable it calls &sub($ref, $ppem)
35
36   $t->XML_element($context, $depth, $key, $value)
37       Outputs device metrics a little more tidily
