Below code will always show me a transparent png with white background:-
private var cameraRoll:CameraRoll = new CameraRoll();
protected function browseForImage(event:MouseEvent):void
{
if( CameraRoll.supportsBrowseForImage )
{
cameraRoll.addEventListener( MediaEvent.SELECT, onImageSelect );
cameraRoll.browseForImage();
}
}
private var imageLoader : Loader;
private function onImageSelect( event:MediaEvent ):void
{
var imagePromise:MediaPromise = event.data;
imageLoader = new Loader();
imageLoader.opaqueBackground = null;
if( imagePromise.isAsync )
{
imageLoader.contentLoaderInfo.addEventListener( Event.COMPLETE, imageLoaded );
imageLoader.loadFilePromise( imagePromise );
}
}
private function imageLoaded( event:Event ):void
{
var myLoaderInfo:LoaderInfo = event.target as LoaderInfo;
var tempBitmapData : BitmapData = new BitmapData(myLoaderInfo.width, myLoaderInfo.height,true,0x00000000);
tempBitmapData.draw(myLoaderInfo.loader);
myImage.source = new Bitmap(tempBitmapData);
}

While the code below always shows me the transparent png:-
private var imageLoader : Loader;
protected function button1_clickHandler(event:MouseEvent):void
{
imageLoader = new Loader();
imageLoader.opaqueBackground = null;
imageLoader.contentLoaderInfo.addEventListener( Event.COMPLETE,onImageLoaded);
imageLoader.load(new URLRequest("Any Tranparent Image url here"));
}
private function onImageLoaded( event:Event ):void
{
var myLoaderInfo:LoaderInfo = event.target as LoaderInfo;
var tempBitmapData : BitmapData = new BitmapData(myLoaderInfo.width, myLoaderInfo.height,true,0x00000000);
tempBitmapData.draw(myLoaderInfo.loader);
myImage.source = new Bitmap(tempBitmapData);
}
myImage is a bitmap image in both the cases.
