CentOS 7.0 - man page for font::ttf::head (centos section 3)

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.

   $t->XML_element($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
