title: How to export high resolution image in Java
body: <p>I tried to take a snapshot of a JFrame and then export the image.  The DPI was only 72dpi, and I would like to know how to increase the resolution.  </p>
  
  <p>I followed the <a href="https://stackoverflow.com/questions/321736/how-to-set-dpi-information-in-an-image">link</a> to set DPI of an image, but it does not really export a higher quality image...  It seems to only change the meta-data of the image file, not actually increase the quality of the export.  </p>
  
  <p>How can I export the image with an actual higher resolution then 72 dpi?</p>
