I have a problem with the openseadragon. I cant convert the ndpi file into deep zoom image(dzi) and it cant directly open the ndpi image.
$file_name = '22R23003.ndpi';
$file = '22R23003';
$converter = new Oz_Deepzoom_ImageCreator();
$converter->create( '../uploads/'.$file_name,'../dzi/'.$file.'.xml');
