Oct 1, 2009I've looked at FileReferenceList and see how to get a list of files from the user's computer.

Is this possible or is FileReferenceList the best/only option?

What I would like to do is get the image dimensions for validation purposes BEFORE the image is received by the server. I know it is possible to check for file size.

View 2 RepliesValid Strategy For Secure Image Upload From Flash Client?
Apr 27, 2010I'm creating a flash application that will post images to a url for saving to disk/display later. I was wondering what are some suggested strategies for making this secure enough so that the upload is verified as coming from the application and not just some random form post. Is it reliable enough to check referring location realizing that I don't need bulletproof security, or perhaps setting authentication headers is a better strategy even though it seems unreliable from what I have read. The application and the server script will reside on the same domain and is in java - is there a way to check for a 'session' or something like that?
Another thought I had was some sort of simple hashed key type system, I could hard-code a key into the flash application and pass something to the server based on that - the server would also know this key and be able to verify if the value passed was based on that? The app is a public app, so authenticating users is not an option. After more research I am thinking about using a hard coded salt key on both ends, then sending an MD5 hash of the base64 encoded image bytearray+salt to be matched on the server side.
Upload Binary (audio) Data From A Flash Client To .NET Server (WCF/REST/HTTP)?
May 5, 2010I originally tried to capture, encode and upload the audio using Silverlight, but because of the lack of suitable client-side encoding options, I'm now giving Flash a shot (Flash has baked-in support for encoding to Speex).I think I've figured out how to capture and encode the audio... But now what was easy in Silverlight, is the challenge in Flash.My server-side is .NET: MVC2-I'm open to receiving the audio in whatever manner is best- REST, WCF..So that's my question: How could one upload binary data from Flash, to a .NET server-side endpoint

View 1 RepliesActionScript 3.0 :: FileReference.load() -> Loader.loadBytes() - Allow A User To Upload An Image From Their Machine To Be Displayed On A Website?
Jan 22, 2011The purpose of this is too allow a user to upload an image from their machine to be displayed on a website. The code's pretty straight forward and i have it all working fine, but have come across an issue. When certain portrait images are selected to be loaded and displayed, they get rotated at some point in the process and become landscape? There doesn't appear to be any consistency to the way they are rotated. Some are clockwise, some counter clockwise.
The one thing i've noticed though, is that it doesn't appear to be an issue with images that have been re-saved (so simply taken into photoshop and then saved without any modification), only images that are the original source of an image taken by a digital camera? This has got me wondering whether there's a possible issue with flash reading the meta data of the source image? The attached zip file contains the source code and swf, a selection of images from 2 different camera's and a modified image.
Just to note, due to the dimensions of the images, in the source code the bitmap is scaled to 0.1 so that the result can be clearly seen. I've tested this without the scaling and the image still gets rotated. There's a trace in the Event.COMPLETE handler of the Loader.loadbytes() method and you can see from this that the width and height of the loaded image have been switched? Note - due to the size of the zip file (4.6MB) because of the images, i've put them up on my server for download instead.[URL]

ActionScript 3.0 :: Speed Test For Looping Through Array
Dec 23, 2009On the PHP site it was advised to do for loops in a certain way that I have not seen on any recommendations for AS3. I think I found about a 10 times speed increase and I thought I better check that I was not missing something (?) before going through my code and changing it. Very simple and fairly self explanatory (in the faster one the array.length is not calculated every time I think):
Code:
import flash.utils.getTimer;
var time:Number;
var myarray:Array = new Array();
myarray.length=2000000;
time=getTimer();

Get Video Dimensions Before Upload Client-side?
Feb 8, 2011I have an upload form for an video. The user clicks browse and selects a file. How can I get the video dimensions the moment the user selects the file (before the file is even uploaded to the server). It obviously has to be something client-side with maybe javascript/jquery or flash/flex (prefer js//jquery though), but can either of them do this?
View 1 RepliesActionscript 3 :: Calculating The Current Upload Speed (or Throughput)?
Jun 28, 2010I am uploading files using the upload() method of the FileReference class. I want to display the current connection speed and I was wondering what was a good way to do that.
My current technique is to use a Timer every 1 mili second such as follows:
var speed:Function = function(event:TimerEvent):void {
speed = Math.round((currentBytes - lastBytes) / 1024);
lastBytes = currentBytes;
}
var speedTimer:Timer = new Timer(1000);
speedTimer.addEventListener(TimerEvent.TIMER, uploadSpeed);
and currentBytes gets set into the ProgressEvent.PROGRESS. This technique seems imprecise. I was wondering what other ways I could use to calculate the upload speed while uploading and display it in real time.
Javascript :: File Compression Before Upload On The Client-side
Dec 4, 2011Basically I'll be working with large XML files (approx. 20 - 50 MB). These files needs to be uploaded on a server.I know it isn't possible to touch the files with javascript, nor to implement HTTP compression on the client-side.
My question is that if any solution exists (flash / action script) that compresses a file and has a javascript API? The scenario is this:

View 2 RepliesActionScript 3.0 :: Create A Resizing Script For A Client That Is Allowing Users To Upload Photos?
Sep 24, 2009I'm trying to create a resizing script for a client that is allowing users to upload photos through their site. SInce most of the photos will be huge this will help in performance. I've had some experience in the saving of a jpeg from Flash but I'm stuck with the scaling. I'm saving the uploaded file to the server. Reloading it into a movie clip, resizing it based on my desired sizes and then saving it back to the server in its new size. When I'm resizing I'm just using the scale properties to resize the loaded large image. When I get my bitmap data of the scale mc it's not taking the data from the scaled clip it's taking the data from the unscaled mc. So my data is basically the upper left hand corner of the original image instead of the whole image.
I've tried nesting the movie clips so that the top clip isn't scaled.I've tried duplicating the data from the scaled clip into a new non scaled clip and that doesn't work either.I've tried not using scale and just using width and height, doesn't work either.
