NAME
    Font::TTF::Ttc - Truetype Collection class

DESCRIPTION
    A TrueType collection is a collection of TrueType fonts in one file in
    which tables may be shared between different directories. In order to
    support this, the TTC introduces the concept of a table being shared by
    different TrueType fonts. This begs the question of what should happen
    to the ' PARENT' property of a particular table. It is made to point to
    the first directory object which refers to it. It is therefore up to the
    application to sort out any confusion. Confusion only occurs if shared
    tables require access to non-shared tables. This should not happen since
    the shared tables are dealing with glyph information only and the
    private tables are dealing with encoding and glyph identification. Thus
    the general direction is from identification to glyph and not the other
    way around (at least not without knowledge of the particular context).

INSTANCE VARIABLES
    The following instance variables are preceded by a space

    fname (P)
        Filename for this TrueType Collection

    INFILE (P)
        The filehandle of this collection

    The following instance variable does not start with a space

    directs
        An array of directories (Font::TTF::Font objects) for each sub-font
        in the directory

METHODS
  Font::TTF::Ttc->open($fname)
    Opens and reads the given filename as a TrueType Collection. Reading a
    collection involves reading each of the directories which go to make up
    the collection.

  $c->read
    Reads a Collection by reading all the directories in the collection

  $c->find($direct, $name, $check, $off, $len)
    Hunts around to see if a table with the given characteristics of name,
    checksum, offset and length has been associated with a directory earlier
    in the list. Actually on checks the offset since no two tables can share
    the same offset in a TrueType font, collection or otherwise.

  $c->DESTROY
    Closees any opened files by us

BUGS
    No known bugs, but then not ever executed!
