title: How can I convert a PDF file to an image?
body: <p>I'm giving users the ability to upload an image to my Air app, then displaying this image in an image control. But I need to allow for PDF uploading in the same manner, so I need to convert the PDF to an image. I only care about the first page of the PDF they upload for now. </p>
  
  <p>What I'm doing is:
  1) User browses for a file with the file reference control
  2) User chooses the image or PDF to upload
  3) I encode said image to base64 and store it
  4) I then load from that base64 with something like:</p>
  
  <pre><code>public function decodeImage(b64String:String):void{
    var decoder:Base64Decoder = new Base64Decoder();
    decoder.decode(b64String);
    var imgLoader:Loader = new Loader();
    imgLoader.loadBytes(decoder.toByteArray());
    imgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,decodedImageLoaded);
  }
  
  private function decodedImageLoaded(event:Event):void{
    var imgLoader:Loader = (event.target as LoaderInfo).loader;
    var bmp:Bitmap = Bitmap(imgLoader.content);
    imgLoader.removeEventListener(Event.COMPLETE, decodedImageLoaded);
    var img:Image = new Image();
    img.source = bmp;
    this.addChild(img);
  }
  </code></pre>
  
  <p>This method is working great for .gif, .jpg, and .png. At some point in my process, probably the initial upload I need to convert the first page of a PDF to a png so that I can use the rest of this process. </p>
  
  <p>I welcome any ideas with the sole requirement being that it has to be a part of the Air app, I can't use something like ImageMagick that runs on a server, but I could use a component that I can compile in to the finished product.</p>
