Font::TTF::Head(3)    User Contributed Perl Documentation   Font::TTF::Head(3)

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->minsize()
       Returns the minimum size	this table can be. If it is smaller than this,
       then the	table must be bad and should be	deleted	or whatever.

   $t->XML_element($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
