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.
