NAME
       PDF::API2::Basic::TTF::Coverage - Opentype coverage and class definition objects

TITLE
       PDF::API2::Basic::TTF::Coverage - Opentype coverage and class definition objects

DESCRIPTION
       Coverage tables and class definition objects are virtually identical concepts in OpenType.
       Their difference comes purely in their storage. Therefore we can say that a coverage table
       is a class definition in which the class definition for each glyph is the corresponding
       index in the coverage table. The resulting data structure is that a Coverage table has the
       following fields:

       cover
           A boolean to indicate whether this table is a coverage table (TRUE) or a class
           definition (FALSE)

       val A hash of glyph ids against values (either coverage index or class value)

       fmt The storage format used is given here, but is recalculated when the table is written
           out.

       count
           A count of the elements in a coverage table for use with add. Each subsequent addition
           is added with the current count and increments the count.

METHODS
       new($isCover [, vals])

       Creates a new coverage table or class definition table, depending upon the value of
       $isCover. if $isCover then vals may be a list of glyphs to include in order.  If no
       $isCover, then vals is a hash of glyphs against class values.

       read($fh)

       Reads the coverage/class table from the given file handle

       out($fh, $state)

       Writes the coverage/class table to the given file handle. If $state is 1 then the output
       string is returned rather than being output to a filehandle.

       $c->add($glyphid)

       Adds a glyph id to the coverage table incrementing the count so that each subsequent
       addition has the next sequential number. Returns the index number of the glyphid added

       $c->out_xml($context)

       Outputs this coverage/class in XML
