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

NAME

       Font::TTF::Post - Holds the Postscript names for each glyph

DESCRIPTION

       Holds the postscript names for glyphs. Note that they are not held as an array, but as indexes into two lists. The first list is the
       standard Postscript name list defined by the TrueType standard. The second comes from the font directly.

       Looking up a glyph from a Postscript name or a name from a glyph number is achieved through methods rather than variable lookup.

       This class handles PostScript table types of 1, 2, 2.5 & 3, but not version 4.  Support for version 2.5 is as per Apple spec rather than
       MS.

       The way to look up Postscript names or glyphs is:

	   $pname = $f->{'post'}{'VAL'}[$gnum];
	   $gnum = $f->{'post'}{'STRINGS'}{$pname};

INSTANCE VARIABLES

       Due to different systems having different limitations, there are various class variables available to control what post table types can be
       written.

       $Font::TTF::Post::no25
	   If set tells Font::TTF::Post::out to use table type 2 instead of 2.5 in case apps can't handle version 2.5.

       VAL Contains an array indexed by glyph number of Postscript names. This is used when writing out a font.

       STRINGS
	   An associative array of Postscript names mapping to the highest glyph with that name. These may not be in sync with VAL.

       In addition there are the standard introductory variables defined in the standard:

	   FormatType
	   italicAngle
	   underlinePosition
	   underlineThickness
	   isFixedPitch
	   minMemType42
	   maxMemType42
	   minMemType1
	   maxMemType1

METHODS

   $t->read
       Reads the Postscript table into memory from disk

   $t->out($fh)
       Writes out a new Postscript name table from memory or copies from disk

   $t->XML_element($context, $depth, $key, $val)
       Outputs the names as one block of XML

BUGS

       o   No support for type 4 tables
