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
BUGS¶
No known bugs
