NAME
       PDF::API2::Basic::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 (PDF::API2::Basic::TTF::Font objects) for each sub-font in the
           directory

METHODS
       PDF::API2::Basic::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!
