#Ttf font viewer code#

The parts of the code which haven't been implemented yet are: Post There is a lot of code here and plenty of scope. This is done to help ensure that any unexpected and unfreed values are brought to your attention so that you can bug us to keep the module updated properly otherwise the potential for memory leaks due to dangling circular references will exist. Once you've called this method, though, don't expect to be able to do anything else with the Font::TTF::Font object it'll have no internal state whatsoever.ĭeveloper note: As part of the brute-force cleanup done here, this method will throw a warning message whenever unexpected key values are found within the Font::TTF::Font object. Internally, we track things in a structure that can result in circular references, and without calling ' release()' these will not properly get cleaned up by Perl.

NOTE, that it is important that you call this method on any Font::TTF::Font object when you wish to destruct it and free up its memory. After calling this method, do NOT expect to have anything left in the Font::TTF::Font object. Releases ALL of the memory used by the TTF font and all of its component objects. May optionally take a list of table names in which case func is called for each of them in the given order. Calls the table in alphabetical sort order as per the order in the directory: &func($table, $name) $f->dirtyĭirties all the tables in the font $f->tables_do(&func )Ĭalls &func for each table in the font. The data structure in now consistent as a font (we hope).

Sends update to all the tables in the font and then resets all the isDirty flags on each table. Handles start messages from the XML parser. $f->out_xml($filename [, the font in XML format $f->XML_start($context, $tag, %attrs) Returns $f on success and undef on failure, including warnings.Īll output files must include the head table. This can be done by not including a in which case the subroutine will output all the defined tables in the font in alphabetical order. In many cases the user simply wants to output all the tables in alphabetical order. (This means that you cannot have non table information stored in the font object with key length of exactly 4) The list is checked to ensure that only tables that exist are output.

$f->out($fname [, a TTF file consisting of the tables in tablelist. Also reads the head and maxp tables immediately. This has been separated from the open function to allow support for embedded TTFs for example in TTCs. # force read of all glyphs (use read_dat to use lots of memory!) There should be no differences between the outputs of the two runs. Run it once and then again on the output of the first run. Here is the regression test (you provide your own font).

Font::TTF::Font->AddTable($tablename, $class).
