Font::TTF::Hdmx - phpMan

NAME
    Font::TTF::Hdmx - Horizontal device metrics

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

INSTANCE VARIABLES
    Individual metrics are accessed using the following referencing:

        $f->{'hdmx'}{$ppem}[$glyph_num]

    In addition there is one instance variable:

    Num Number of device tables.

  METHODS
  $t->read
    Reads the table into data structures

  $t->out($fh)
    Outputs the device metrics for this font

  $t->minsize()
    Returns the minimum size this table can be. If it is smaller than this,
    then the table must be bad and should be deleted or whatever.

  $t->tables_do(&func)
    For each subtable it calls &sub($ref, $ppem)

  $t->XML_element($context, $depth, $key, $value)
    Outputs device metrics a little more tidily
