NAME

       Font::TTF::Utils - Utility functions to save fingers

DESCRIPTION

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

FUNCTIONS

       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
	   v	   Version number (FIXED)

       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

   TTF_word_utf8($str)
       Returns the UTF8 form of the 16 bit string, assumed to be in big endian order, including surrogate handling

   TTF_utf8_word($str)
       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 wide

   XML_outhints
       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.

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

       $dia
	   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

       numDots
	   Number of dots in the circle

       numPoints
	   Number of curve points to use to create each dot

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

       pname
	   Postscript name to give the glyph. Defaults to uni25CC.

       -dRadius
	   Radius of each dot.

BUGS

       No known bugs

NAME

       Font::TTF::Ttc - Truetype Collection class

DESCRIPTION

       A TrueType collection is a collection of TrueType fonts in one file in which tables may be shared between different directories. In order
       to support this, the TTC introduces the concept of a table being shared by different TrueType fonts. This begs the question of what should
       happen to the ' PARENT' property of a particular table. It is made to point to the first directory object which refers to it. It is
       therefore up to the application to sort out any confusion.  Confusion only occurs if shared tables require access to non-shared tables.
       This should not happen since the shared tables are dealing with glyph information only and the private tables are dealing with encoding and
       glyph identification. Thus the general direction is from identification to glyph and not the other way around (at least not without
       knowledge of the particular context).

INSTANCE VARIABLES

       The following instance variables are preceded by a space

       fname (P)
	   Filename for this TrueType Collection

       INFILE (P)
	   The filehandle of this collection

       The following instance variable does not start with a space

       directs
	   An array of directories (Font::TTF::Font objects) for each sub-font in the directory

METHODS

   Font::TTF::Ttc->open($fname)
       Opens and reads the given filename as a TrueType Collection. Reading a collection involves reading each of the directories which go to make
       up the collection.

   $c->read
       Reads a Collection by reading all the directories in the collection

   $c->find($direct, $name, $check, $off, $len)
       Hunts around to see if a table with the given characteristics of name, checksum, offset and length has been associated with a directory
       earlier in the list.  Actually on checks the offset since no two tables can share the same offset in a TrueType font, collection or
       otherwise.

   $c->DESTROY
       Closees any opened files by us

BUGS

       No known bugs, but then not ever executed!
