NAME

       Font::TTF::Anchor - Anchor points for GPOS tables

DESCRIPTION

       The Anchor defines an anchor point on a glyph providing various information depending on how much is available, including such information
       as the co-ordinates, a curve point and even device specific modifiers.

INSTANCE VARIABLES

       x   XCoordinate of the anchor point

       y   YCoordinate of the anchor point

       p   Curve point on the glyph to use as the anchor point

       xdev
	   Device table (delta) for the xcoordinate

       ydev
	   Device table (delta) for the ycoordinate

       xid XIdAnchor for multiple master horizontal metric id

       yid YIdAnchor for multiple master vertical metric id

METHODS

   new
       Creates a new Anchor

   read($fh)
       Reads the anchor from the given file handle at that point. The file handle is left at an arbitrary read point, usually the end of
       something!

   out($fh, $style)
       Outputs the Anchor to the given file handle at this point also addressing issues of deltas. If $style is set, then no output is sent to the
       file handle. The return value is the output string.

   $a->out_xml($context)
       Outputs the anchor in XML

NAME

       Font::TTF::Loca - the Locations table, which is intimately tied to the glyf table

DESCRIPTION

       The location table holds the directory of locations of each glyph within the glyf table. Due to this relationship and the unimportance of
       the actual locations when it comes to holding glyphs in memory, reading the location table results in the creation of glyph objects for
       each glyph and stores them here.  So if you are looking for glyphs, do not look in the "glyf" table, look here instead.

       Things get complicated if you try to change the glyph list within the one table.  The recommendation is to create another clean location
       object to replace this table in the font, ensuring that the old table is read first and to transfer or copy glyphs across from the read
       table to the new table.

INSTANCE VARIABLES

       The instance variables do not start with a space

       glyphs
	   An array of glyph objects for each glyph.

       glyphtype
	   A string containing the class name to create for each new glyph. If empty, defaults to Font::TTF::Glyph.

METHODS

   $t->new
       Creates a new location table making sure it has a glyphs array

   $t->read
       Reads the location table creating glyph objects (Font::TTF::Glyph) for each glyph allowing their later reading.

   $t->out($fh)
       Writes the location table out to $fh. Notice that not having read the location table implies that the glyf table has not been read either,
       so the numbers in the location table are still valid. Let's hope that "maxp/numGlyphs" and "head/indexToLocFmt" haven't changed otherwise
       we are in big trouble.

       The function uses the OUTLOC location in the glyph calculated when the glyf table was attempted to be output.

   $t->out_xml($context, $depth)
       No need to output a loca table, this is dynamically generated

   $t->glyphs_do(&func)
       Calls func for each glyph in this location table in numerical order:

	   &func($glyph, $glyph_num)

BUGS

       None known
