Font::TTF::Utils - Utility functions to save fingers
Lots of useful functions to save my fingers, especially for trivial tables
The following functions are exported
($val, CW$pos) = TTF_Init_Fields ($str, CW$pos)
Given a field description from the DATA section, creates an absolute entry
in the fields associative array for the class
TTF_Read_Fields($obj, CW$dat, CW$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
A TrueType types equivalent of Perls unpack function. Thus $fmt consists of
type followed by an optional number of elements to read including *. The type
may be one of:
v Version number (FIXED)
Note that FUNIT, FWORD and UFWORD are not data types but units.
Returns array of scalar (first element) depending on context
CW$dat = TTF_Out_Fields($obj, CW$fields, CW$len)
Given the fields table from TTF_Init_Fields writes out the instance variables from
the object to the filehandle in TTF binary form.
CW$dat = TTF_Pack($fmt, CW@data)
The TrueType equivalent to Perls pack function. See details of TTF_Unpack
for how to work the $fmt string.
($num, CW$range, CW$select, CW$shift) = TTF_bininfo($num)
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 <data> blocks each 16 bytes wide
Converts a binary string of hinting code into a textual representation
make_circle($f, CW$cmap, [$dia, CW$sb, CW$opts])
Adds a dotted circle to a font. This function is very configurable. The
parameters passed in are:
There are various options to control all sorts of interesting aspects of the circle
Font to work with. This is required.
A cmap table (not the val sub-element of a cmap) to add the glyph too. Optional.
Optional diameter for the main circle. Defaults to 80% em
Side bearing. The left and right side-bearings are always the same. This value
defaults to 10% em.
Number of dots in the circle
Number of curve points to use to create each dot
Unicode reference to store this glyph under in the cmap. Defaults to 0x25CC
Postscript name to give the glyph. Defaults to uni25CC.
Radius of each dot.
No known bugs
