NAME

       Font::TTF::Segarr - Segmented array

DESCRIPTION

       Holds data either directly or indirectly as a series of arrays. This class looks after the set of arrays and masks the individual sub-
       arrays, thus saving a class, we hope.

INSTANCE VARIABLES

       All instance variables do not start with a space.

       The segmented array is simply an array of segments

       Each segment is a more complex affair:

       START
	   In terms of the array, the address for the 0th element in this segment.

       LEN Number of elements in this segment

       VAL The array which contains the elements

METHODS

   Font::TTF::Segarr->new($size)
       Creates a new segmented array with a given data size

   $s->fastadd_segment($start, $is_sparse, @dat)
       Creates a new segment and adds it to the array assuming no overlap between the new segment and any others in the array. $is_sparse
       indicates whether the passed in array contains "undef"s or not. If false no checking is done (which is faster, but riskier). If equal to 2
       then 0 is considered undef as well.

       Returns the number of segments inserted.

   $s->add_segment($start, $overwrite, @dat)
       Creates a new segment and adds it to the array allowing for possible overlaps between the new segment and the existing ones. In the case of
       overlaps, elements from the new segment are deleted unless $overwrite is set in which case the elements already there are over-written.

       This method also checks the data coming in to see if it is sparse (i.e. contains undef values). Gaps cause new segments to be created or
       not to over-write existing values.

   $s->tidy
       Merges any immediately adjacent segments

   $s->at($addr, [$len])
       Looks up the data held at the given address by locating the appropriate segment etc. If $len > 1 then returns an array of values, spaces
       being filled with undef.

   $s->remove($addr, [$len])
       Removes the item or items from addr returning them as an array or the first value in a scalar context. This is very like "at", including
       padding with undef, but it deletes stuff as it goes.

   $s->copy
       Deep copies this array

   $s->copy_seg($seg)
       Creates a deep copy of a segment

BUGS

       No known bugs.

NAME

       Font::TTF::Head - The head table for a TTF Font

DESCRIPTION

       This is a very basic table with just instance variables as described in the TTF documentation, using the same names. One of the most
       commonly used is "unitsPerEm".

INSTANCE VARIABLES

       The "head" table has no internal instance variables beyond those common to all tables and those specified in the standard:

	   version
	   fontRevision
	   checkSumAdjustment
	   magicNumber
	   flags
	   unitsPerEm
	   created
	   modified
	   xMin
	   yMin
	   xMax
	   yMax
	   macStyle
	   lowestRecPPEM
	   fontDirectionHint
	   indexToLocFormat
	   glyphDataFormat

       The two dates are held as an array of two unsigned longs (32-bits)

METHODS

   $t->read
       Reads the table into memory thanks to some utility functions

   $t->out($fh)
       Writes the table to a file either from memory or by copying. If in memory (which is usually) the checkSumAdjustment field is set to 0 as
       per the default if the file checksum is not to be considered.

   $t->XML_element($context, $depth, $key, $value)
       Handles date process for the XML exporter

   $t->update
       Updates the head table based on the glyph data and the hmtx table

   $t->getdate($is_create)
       Converts font modification time (or creation time if $is_create is set) to a 32-bit integer as returned from time(). Returns undef if the
       value is out of range, either before the epoch or after the maximum storable time.

   $t->setdate($time, $is_create)
       Sets the time information for modification (or creation time if $is_create is set) according to the 32-bit time information.

BUGS

       None known
