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. | |
