Thanks you, i have the error yet :
ZipArchive::extractTo(): Permission denied in /var/www/ims/ims/lib/PHPDocx/classes/AutoLoader.inc(2) : eval()'d code on line 2
But the pdf is generated (with a bad/incomplete layout :/)
I think, i'm going to buy this library version corporate now but you think i can get a better result than actually with generatePDF()
