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 USHORTNote 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

No known bugs
