Open url request from PopUpManager

Question

Hi,
I have a function which opens a new browser window with the result of a URL request (an image). I wonder if  I can do the same but with a window "embedded" in the flash application.
I saw there is a class called PopUpManager. I understood that I have to create a new component ("popup") with the data for the new window. The problem is that I don't know how to pass the result of the URL request to that popup component.
Is it possible at all? Is there any other alternative?
Regards,
Manolo

Hi there
Yep cool with the PopUpManager.centrePopUp.
As for saving an image.  You can save graphics from Flex by specifiying a rectangular region you want to save.  You can save the selected region out as a jpg or a png using the encoders.  In the example below I have saved out an image. 
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
     import mx.graphics.codec.JPEGEncoder;
     import flash.utils.ByteArray;
     private function saveImage():void {
          var bitmapData:BitmapData = new BitmapData(myImage.contentWidth, myImage.contentHeight);
          bitmapData.draw(myImage);    
          var jpeg:JPEGEncoder = new JPEGEncoder();
          var byteArray:ByteArray = jpeg.encode(bitmapData);
          var file:FileReference = new FileReference();
          file.save(byteArray,'TestImage.jpg');
]]>
</mx:Script>
<mx:Image id="myImage" x="78" y="33" width="283" height="180" source="http://www.maniacworld.com/amazing-cars.jpg"/>
<mx:Button x="78" y="236" label="Button" click="saveImage()"/>
</mx:Application>
Note you need to be compiling for Flash PLayer 10 in your Flex compiler settings as that allow you to read and write local files.
Hope it helps
