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 identifica‐
tion. Thus the general direction is from identification to glyph and
not the other way around (at least not without knowledge of the partic‐
ular 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 ear‐
lier 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!
