public function COMPLETEListener(e:Event){
myBitmap = e.target.loader.content;
}

public function destroy(){
if(myBitmap is Bitmap){
myBitmap.bitmapData.dispose();
}
}

works fine for me load some big image and see the difference in the taskmanager

should work!

var loader:Loader = new Loader();
addChildAt(loader,1);

btn1.addEventListener(MouseEvent.CLICK, getFile);
btn2.addEventListener(MouseEvent.CLICK, getFile);

btn1.dispatchEvent(new MouseEvent(MouseEvent.CLICK)); //loads first file

function getFile(e:MouseEvent):void {
removeChild(loader);
addChildAt(loader,1);
var file = “mc” + e.target.name.substr(3) + “.swf”;
loader.load(new URLRequest(file));

var mem:String = Number( System.totalMemory / 1024 / 1024 ).toFixed( 2 ) + ‘Mb’;
trace( mem );
}

sorry

var len:int = _loader.length;
for ( var i:int ; i < len ; i++ )
{
var l:Loader = Loader(_loader.pop());
if(l.contentLoaderInfo.childAllowsParent && l.contentLoaderInfo.content is Bitmap){
(l.contentLoaderInfo.content as Bitmap).bitmapData.dispose(); // remove bitmap from memory
}

l.unload();
removeChild(l);
l = null;
}

_loader = null;
_loader = new Array();
}
}
}

to compile it create a fla file with this class as documentClass and to simpleButtons called btn1 and btn2 , and change the file name.

i load the same image 100 times and try the method i found here, i’m working on a macbook pro and in the activity monitor i checked that the memory for the firefox goes up in about 130 Mb, and when the clean method is executed the memory goes down about 50 MB, and it stays there. the whole memory is not cleaned.

if someone finds code errors please let me know . this issue is affecting my projects.

bye

Did you invoke dispose after Event.COMPLETE or unload() ?

[...] http://www.dreaminginflash.com/2007/10/22/memory-leak-in-as3-loader-class/ [...]

when running Simulate Download in Flash IDE, got eeror:
Error: Error #2099: The loading object is not sufficiently loaded to provide this information.
at flash.display::LoaderInfo/get childAllowsParent()
at com.cfour.app.afl.mural::PopupWindow/disposeImage()
at com.cfour.app.afl.mural::PopupWindow/closeHandler()

trace(li) got null.

Why?
