// Alcal: $font2cache modification
// This modification creates utf-8 fonts only the first time,
// after that it uses cache file which dramatically reduces execution time
if (!file_exists($fontfile.'.cached')){
// calculate $font first time
$subsetchars = array_fill(0, 512, true); // fill subset for all chars 0-512
$font = $this->_getTrueTypeFontSubset($font, $subsetchars); // this part is actually slow!
// and then save $font to file for further use
$fp=fopen($fontfile.'.cached','w');
$flat_array = serialize($font); //
fwrite($fp,$flat_array);
fclose($fp);
}
else {
// cache file exist, load file
$fp=fopen($fontfile.'.cached','r');
$flat_array = fread($fp,filesize($fontfile.'.cached'));
fclose($fp);
$font = unserialize($flat_array);
}
