DESCRIPTION

       Handles the Feature Parameters valus forCharacter Variants features

INSTANCE VARIABLES

       INFILE
	   The read file handle

       OFFSET
	   Location of the file in the input file

       Format
	   Table format - set to 0

       UINameID
	   The 'name' table name ID that specifies a string (or strings, for multiple languages) for a user-interface label for this feature

       TooltipNameID
	   The 'name' table name ID for tooltip text for the feature

       SampleTextNameID
	   The 'name' table name ID for sample text to illustrate the feature

       NumNamedParms
	   The number of named parameters

       FirstNamedParmID
	   The 'name' table name ID for the first named parameter

       Characters
	   An array holding the unicode values of the characters for which the feature provides glyph variants

METHODS

   $t->read
       Reads the Feature Params

   $t->out($fh)
       Writes the FeatureParams table to the output

   Font::TTF::Features::Sset->new()
       Creates a new FeatureParams object.  Values for INFILE and OFFSET canbe passed as parameters

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, don't 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
