Image loading problem

[bluemagica]

private function getImage():void
            {
                fr.addEventListener(Event.SELECT,imgLoad);
                fr.addEventListener(Event.COMPLETE,imgExtract);
                fr.browse([new FileFilter("Images(*.png,*.jpg,*.bmp)","*.png;*.jpg;*.jpeg;*.bmp")]);
            }           
            private function imgLoad(e:Event):void
            {
                fr.load();
            }
            private function imgExtract(e:Event):void
            {
                var img_br:ByteArray = new ByteArray();
                img_br = fr.data as ByteArray;
               
                var loader:Loader = new Loader();
                loader.addEventListener(Event.COMPLETE,imgDisplay);
                loader.addEventListener(IOErrorEvent.IO_ERROR,imgLoading);
                loader.loadBytes(img_br);
                pathtxt.text = "Loading "+img_br.length+" : "+loader;
            }
            private function imgLoading(e:IOErrorEvent):void
            {
                pathtxt.text = "here";
                //imgProgress.setProgress(e.bytesLoaded,e.bytesTotal);
            }
            private function imgDisplay(e:Event):void
            {
                image = e.currentTarget.loader.content as Bitmap;
                imgPreview.addChild(image);
                pathtxt.text = fr.name;               
            }

When I run the above, it doesn't seem to trigger the imgDisplay or imgLoading functions(imgLoading was supposed to be progress event, but I changed it for testing).....it seems, the eventListeners are not working, any idea?

What is fr? File Reference?

When I did this in my current application, I had to take a step back and research because personally I think I'm the last known developer still using the stock Flash CS4 IDE instead of Flex. I came across more than one article talking about how bug-ridden FileReference.load() was so I took a different approach. Use a File.browse() to get your local path, and then revert to a URLRequest to load the actual image. I can't show you a work example, but I can pull bits and pieces from my current project:

		private function loadLocalPrev(event:MouseEvent) {
			var localRef:File;
			localRef = new File();
			localRef.addEventListener(Event.SELECT, selectHandler);
			localRef.browse([new FileFilter("Images (*.jpg, *.jpeg, *.gif, *.png)", "*.jpg;*.jpeg;*.gif;*.png")]);
		}

        private function selectHandler(event:Event):void {
			trace("Loading image: " + event.target.nativePath);			
            if (event.target.nativePath != null) {
				loadSinglePrev( event.target.nativePath);
			} else {
				new Alert(_stage, _newMoviePic.x, _newMoviePic.y, _newMoviePic.width, _newMoviePic.height, false, false, "Data Required", "You must select a file.");
			}
        }

		private function loadSinglePrev(url:String) {
			trace("Loading image: " + url);
			for (var i = 0; i< _newMoviePic._previews.length; i++) {
				_newMoviePic.removeChild(_newMoviePic._previews[i].img);
			}
			_newMoviePic._previews = [];
			var img:Image = new Image(_newMoviePic, 126, 195, false);
			img.loadImage(url, doNothing);
			img._id = 0;
			img.x = 105;
			img.y = 172;
			_newMoviePic.addChild(img);
			var o:Object = {};
			o.img = img;
			o.id = 0;
			o.url = url;
			_newMoviePic._previews.push(o);
			img.doubleClickEnabled=true;
			img.addEventListener(MouseEvent.CLICK, selectPreview);
			img.addEventListener(MouseEvent.DOUBLE_CLICK, downloadAndfinalizeAdd);
			
		}

// this is from the Image class' loadImage() function
		public function loadImage(url:String, callback:Function = null) {
			var urlGet = new URLRequest(url);
			_imageloader.mouseEnabled=false;
			configureListeners(_imageloader.contentLoaderInfo);
			_imageloader.load(urlGet);
			this.addChild(_imageloader);
			if (_showProg) {
				this.addChild(_imageProgress);
			}
			_callBack = callback;
		}

Hopefully you can get the idea from there. Maybe it will help you, maybe it won't.

Nice Maplestory avatar by the way; been meaning to mention that for a while now.

umm, there is no nativePath. I don't know about air, but this is a web-app, and it seems I have no way to find the local path to the file from file reference.
http://www.adobe.com/devnet/flash/qu...nce_class_as3/
There it is said: "when the user has selected a file to open, there is no way to determine the local path where the file is located. Only the name of the file is available."
if I could get the path some way, then I think your solution will work!
And thanks, I like the avatar very much.....it matches me perfectly, lol!

And yes, fr is filereference!




I don't think the filereference is the problem though, cause as you can see from the path text line(well, you can't see, but assume), the file is being loaded, and I am getting the bytearray, so I guess parsing that bytearray through loadBytes is causing the problem somehow!

Ahh. Yet another unfortunate side-effect of pushing Flex/AIR into the same forum. You're using Flex on the web, and I'm using AIR locally.
