       PDF::API3::Compat::API2::Basic::TTF::Utils - Utility functions to save

       Lots of useful functions	to save	my fingers, especially for trivial

       The following functions are exported

   ($val, $pos)	= TTF_Init_Fields ($str, $pos)
       Given a field description from the "DATA" section, creates an absolute
       entry in	the fields associative array for the class

   TTF_Read_Fields($obj, $dat, $fields)
       Given a block of	data large enough to account for all the fields	in a
       table, processes	the data block to convert to the values	in the objects
       instance	variables by name based	on the list in the "DATA" block	which
       has been	run through "TTF_Init_Fields"

   TTF_Unpack($fmt, $dat)
       A TrueType types	equivalent of Perls "unpack" function. Thus $fmt
       consists	of type	followed by an optional	number of elements to read
       including *. The	type may be one	of:

	   c	   BYTE
	   C	   CHAR
	   f	   FIXED
	   F	   F2DOT14
	   l	   LONG
	   L	   ULONG
	   s	   SHORT
	   S	   USHORT

       Note that "FUNIT", "FWORD" and "UFWORD" are not data types but units.

       Returns array of	scalar (first element) depending on context

   $dat	= TTF_Out_Fields($obj, $fields,	$len)
       Given the fields	table from "TTF_Init_Fields" writes out	the instance
       variables from the object to the	filehandle in TTF binary form.

   $dat	= TTF_Pack($fmt, @data)
       The TrueType equivalent to Perl's "pack"	function. See details of
       "TTF_Unpack" for	how to work the	$fmt string.

   ($num, $range, $select, $shift) = TTF_bininfo($num)
       Calculates binary search	information from a number of elements

       Returns the UTF8	form of	the 16 bit string, assumed to be in big	endian
       order, including	surrogate handling

       Returns the 16-bit form in big endian order of the UTF 8	string,
       including surrogate handling to Unicode.

   XML_hexdump($context, $dat)
       Dumps out the given data	as a sequence of <data>	blocks each 16 bytes

       Converts	a binary string	of hinting code	into a textual representation

   make_circle($f, $cmap, [$dia, $sb, $opts])
       Adds a dotted circle to a font. This function is	very configurable. The
       parameters passed in are:

       $f  Font	to work	with. This is required.

	   A cmap table	(not the 'val' sub-element of a	cmap) to add the glyph
	   too.	Optional.

	   Optional diameter for the main circle. Defaults to 80% em

       $sb Side	bearing. The left and right side-bearings are always the same.
	   This	value defaults to 10% em.

       There are various options to control all	sorts of interesting aspects
       of the circle

	   Number of dots in the circle

	   Number of curve points to use to create each	dot

       uid Unicode reference to	store this glyph under in the cmap. Defaults
	   to 0x25CC

	   Postscript name to give the glyph. Defaults to uni25CC.

	   Radius of each dot.

       No known	bugs
