NAMEFont::TTF::Utils − Utility functions to save fingers
DESCRIPTIONLots of useful functions to save my fingers, especially for trivial tables
FUNCTIONSThe 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, $dat)Dumps out the given data as a sequence of <data> blocks each 16 bytes wide
XML_outhintsConverts a binary string of hinting code into a textual representation
make_circle($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 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.
