Hi Kevin, I feel your pain! Having been through this one before ...
It doesn't work quite as one (well, myself in any case) would expect on first
look.
Even when feeding in an already complete byteArray, you still have to listen
for the load Complete event.
Up until that event, loader.content remains null.
_jpgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,jpgCompleteHandler);
try something like this (it could do with an IoError event listener as
well,perhaps?) :
private var _ldr:Loader
private function myTest():void{
//get ByteArray from Image Component content
var testBM:Bitmap = testImg.content as Bitmap;
var myByte:ByteArray = new
JPEGEncoder().encode(testBM.bitmapData);
//convert ByteArray to Bitmap
_ldr = new Loader();
_ldr.addEventListener(Event.COMPLETE,bitmapLoaded);
_ldr.loadBytes(myByte);
}
private function bitmapLoaded(event:Event)
{
_ldr.removeEventListener(Event.COMPLETE,bitmapLoaded)
//reset source
myImage.source = _ldr.content;
}
(Personally I like to keep a permanent reference to the loader, rather than
casting it from the event.target)
Alex, I think it does work as it's meant to, but I would really like to have a
means to do the same byteArray > bitmapData conversion synchronously without
the listener.
If anyone can help with that, then please let me know!
Also, I did have some difficulty with the docs in this respect, a small sample
like the above would help greatly imho.
Jim.
