title: How can i change modal transparency in Flex
body: <p>I create a modal window with PopUpManager</p>
  
  <pre><code>_zoomImgPopUp = PopUpManager.createPopUp(this, Image, true) as Image;
  </code></pre>
  
  <p>When the modal window is opened, all background is gray and with blur.
  How can i change color, blur and transparency of background.</p>
  
  <p>I find this article 
  <a href="http://mprami.wordpress.com/2008/04/22/alert_popup_modal_transparancy_color_blur_changes/" rel="nofollow">http://mprami.wordpress.com/2008/04/22/alert_popup_modal_transparancy_color_blur_changes/</a></p>
  
  <p>but it is for "mx" application. I need something with "spark" components.</p>
  
  <p>UPD: Solved. It must be:</p>
  
  <pre><code>_zoomImgPopUp.setStyle("modalTransparency", 0);
  _zoomImgPopUp.setStyle("modalTransparencyBlur", 0);
  PopUpManager.addPopUp(_zoomImgPopUp, this, true);
  </code></pre>
