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 Given a field description from the CWDATA section, creates an absolute entry in the fields associative array for the class 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 CWDATA block which has been run through CWTTF_Init_Fields A TrueType types equivalent of Perls CWunpack function. Thus CW$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 CWFUNIT, CWFWORD and CWUFWORD are not data types but units.

Returns array of scalar (first element) depending on context Given the fields table from CWTTF_Init_Fields writes out the instance variables from the object to the filehandle in TTF binary form. The TrueType equivalent to Perl's CWpack function. See details of CWTTF_Unpack for how to work the CW$fmt string. 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. 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 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.
