Cover image is not shown in explorer

Question

Hi guys, I've already got a new lap which runs W7 ultimate (x64) and Adobe Reader X 10.1.3 but the cover image (the first page) of PDF fiels is not shown in Window's Explorer. Any hints?.
Thanks in advance,

Answer 1

try to flush the image.
   image.flush():
   g.drawImage(image, 0, 0, null);
or try
   Toolkit.getDefaultToolkit().prepareImage(image, -1, -1, null);
    g.drawImage(image, 0, 0, null);
If the image isn't displayed, just try a new paint after a while (for example after 1 second).
Another way is to implement the ImageObserver interface who can announce you with the imageUpdate() method when the entire image is loaded:
   public boolean imageUpdate(Image img,int info,int x,int y,int width,int height)
     if(info & ALLBITS)
       //the image is entirely loaded....
   }
