) - the ’fontfile’ parameter MUST include the absolute path along with the filename! If you only supply a relative path, the function will find the font file but for some reason it will return an array filled with ZEROS!
while ($file = $dir->read()) {
if(strstr($file,'.ttf') ) { // include only .ttf files
$fontstmp[] = $this->dir_font.'/'.$file;
}
}
// prefix font file name with absolute path $text_font = dirname($_SERVER['DOCUMENT_ROOT'].$_SERVER['SCRIPT_NAME']). '/ttf/' . $text_font;
Your modified veriword file solved my problem too!

I had no problem with the zip; strange. Anyway, here is a patch of his changes, so as not to paste the whole thing:
Could someone please paste the modified veriword code into a message here. The .zip file is empty for me no matter how I access it, and I have no clue what’s been done to veriword.php.
