NAMEFont::TTF::Utils - Utility functions to save fingersDESCRIPTIONLots of useful functions to save my fingers, especially for trivial tablesFUNCTIONSThe 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 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 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, $dat)Dumps out the given data as a sequence of <data> blocks each 16 bytes wideXML_outhintsConverts a binary string of hinting code into a textual representationmake_circle($f, $cmap, [$dia, $sb, $opts])Adds a dotted circle to a font. This function is very configurable. The parameters passed in are:
There are various options to control all sorts of interesting aspects of the circle
