Font::TTF::Head - The head table for a TTF Font
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".
The "head" table has no internal instance variables beyond those common to all tables and
those specified in the standard:
The two dates are held as an array of two unsigned longs (32-bits)
Reads the table into memory thanks to some utility functions
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
Updates the head table based on the glyph data and the hmtx table
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.
Sets the time information for modification (or creation time if $is_create is set)
according to the 32-bit time information.
