PDF::API2::TTF::Utils - Utility functions to save fingers
Lots of useful functions to save my fingers, especially for trivial tables
The following functions are exported
Given a field description from the DATA
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 DATA
block which has been run
through TTF_Init_Fields
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
Given the fields table from TTF_Init_Fields
writes out the instance variables from
the object to the filehandle in TTF binary form.
The TrueType equivalent to Perl's pack
function. See details of TTF_Unpack
for how to work the $fmt string.
Calculates binary search information from a number of elements
Returns the UTF8 form of the 16 bit string, assumed to be in big endian order, including surrogate handling
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 blocks each 16 bytes wide
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. |
No known bugs
