NAME
PDF::API3::Compat::API2::Basic::TTF::Utils - Utility functions to save fingersDESCRIPTION
Lots of useful functions to save my fingers, especially for trivial tablesFUNCTIONS
The following functions are exported($val, $pos) = TTF_Init_Fields ($str, $pos)
Given a field description from the "DATA" section, creates an absolute entry in the fields associative array for the classTTF_Read_Fields($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
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 elementsTTF_word_utf8($str)
Returns the UTF8 form of the 16 bit string, assumed to be in big endian order, including surrogate handlingTTF_utf8_word($str)
Returns the 16-bit form in big endian order of the UTF 8 string, including surrogate handling to Unicode.XML_hexdump($context, $dat)
Dumps out the given data as a sequence of <data> blocks each 16 bytes wideXML_outhints
Converts a binary string of hinting code into a textual representationmake_circle($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.
