Saving Syntax Incorrect?

[ Edited ]

Hey Everyone,

 

When trying to save an image through use of a ByteArray I'm getting a "Error #2038: File I/O Error." error...

 

Is my syntax incorrect?

 

 

var loader:Loader = (e.target as LoaderInfo).loader;
			
var bitmapData:BitmapData = new BitmapData(loader.width, loader.height);
var jpgEncoder:JPGEncoder = new JPGEncoder(80);
var imgData:ByteArray = jpgEncoder.encode(bitmapData);
			
var imgFileToSave:File = File.applicationStorageDirectory;	
imgFileToSave.addEventListener(Event.COMPLETE, imageFileDidSave);
			imgFileToSave.addEventListener(IOErrorEvent.IO_ERROR, function(e:IOErrorEvent):void
{
     trace(e.toString());
});
imgFileToSave.save(imgData, "Image.jpg");

 *scratches head*

hey,

 

i havent tested it out but at first glance this line:

 

 

imgData.draw(loader);

 

seems out of place and premature? imgData is defined later. dont know if that was a typo though.

 

Edit: at a second glance it seems that line should be:

 

bitmapData.draw(loader);

 

good luck!

 

Edit #2: just saw your reply. i'll keep testing!

Re: Saving Syntax Incorrect?

This is from a screen capture code of mine.  Adapt as needed.

 

private function SaveImage( view : DisplayObject ) : void
{  
    var jpg_encoder : JPEGEncoder = new JPEGEncoder( 100 );  
      
    var img: ImageSnapshot = ImageSnapshot.captureImage( view, 0, jpg_encoder );

      
    var download_file_ref : FileReference = new FileReference();
    download_file_ref.save( img.data, "image.jpg" );
}

 If this does not help or you still get an error, try it in AIR.  If OK in AIR, then it is a simulator issue.

Re: Saving Syntax Incorrect?

yea it's fine in AIR which is why I'm confused... must be a simulator issue

Try not saving in the application storage directory.  Use my little example to save the file.  It may be a a tighter sandbox on the simulator.  Really should not be able to browse that directory anyway.

 

var download_file_ref : FileReference = new FileReference();
    download_file_ref.save( img.data, "image.jpg" );

You may want to report that to the BB issues database.

JRab, it's not too complex, like I said it works fine on AIR

jtegen : I think I'm going to

 

private function fetchImage():void
{			
        var urlLoader:URLLoader = new URLLoader();
	urlLoader.addEventListener(Event.COMPLETE, htmlDidLoad);
			
	urlLoader.addEventListener(IOErrorEvent.IO_ERROR, function(e:IOErrorEvent):void
	{
	var alertDialog:AlertDialog = new AlertDialog();
				alertDialog.dialogSize = DialogSize.SIZE_SMALL;
				alertDialog.message = "Sorry, a valid internet or data connection could not be made! Please check your connection and try again later.";
			});
			
			var request:URLRequest = new URLRequest("http://www.somewebsite.com/");
			urlLoader.load(request);
		}
		
		private function htmlDidLoad(e:Event):void
		{
			var htmlData:String = String(e.target.data);
			var htmlRegData:Array = htmlData.match(/someregex/);
			var imageURLData:String = htmlRegData[0];

			var htmlPrefix:String = "http://www.somewebsite.com";
			
			var imgFileToSave:File = File.applicationStorageDirectory;	
			
			
			if (!imgFileToSave.resolvePath(imageURL.substring(28, imageURL.length)).exists)
			{
				imageURL = htmlPrefix.concat(imageURLData);
				
				var loader:Loader = new Loader;
				var imgReq:URLRequest = new URLRequest(imageURL);
				loader.load(imgReq);
				
				loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageDidLoad);
				loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, function():void
				{
					var alertDialog:AlertDialog = new AlertDialog();
					alertDialog.dialogSize = DialogSize.SIZE_SMALL;
					alertDialog.message = "Sorry, the internet connection has been lost! Please check your connection and try again later.";
				});
			}
			else
			{
				var alertDialog:AlertDialog = new AlertDialog();
				alertDialog.dialogSize = DialogSize.SIZE_SMALL;
				alertDialog.message = "somestuff";
			}
		}
