ActionScript 3.0 :: Send A Bytearray Object To A Javascript Function?
Aug 11, 2009I need to be able to send a bytearray object to a javascript function or a java method, but I was wondering if I could do it using XMLHTTPRequest.
import asfiles.encoding.JPEGEncoder;import flash.display.Bitmap;import flash.display.BitmapData;import flash.external.[code]...
So I have a video that plays stream from a webcam,I will click a button and take a picture. I encode that picture using JPEGEncoder then I store it in a ByteArray.How do I send that data over to either a javascript function or a java class?I don't want to use the navigateToURL (URLRequest) method because that will redirect my page.Is there a way to send the data to a function while still staying on the same page?For example, make a asynchronous call to a javascript function or java method?
JavaScript :: Upload ByteArray Image On Facebook With SDK
Apr 14, 2012I'm trying to upload a photo on Facebook using Javascript SDK. In particular I generate a base64 encoded bytearray from my Actionscript3 app, I pass it to Javascript file using ExternalInterface, and from that I decode the bytearray and I try to upload to FB. But it give me this error:
{"error":{"message":"(#324) Requires upload file","type":"OAuthException","code":324}}
I tried to upload an image simply from url, and in that way it goes well! This is my Javascript code:

Php :: Flex - Send A FLV Format Data In ByteArray Using URLloader To A Script?
Dec 15, 2010Im creating flash game that have the functionality to capture/record its gameplay that can be viewed later by the user, like a replay.
As for now Im already able to record the game and write it into a flv format in a ByteArray variable.
What Im working right now is how to send that ByteArray(the video file) to a php script and save it to a web server.
I've run into the URLLoader in flash where it can send the data and php will receive it thru the POST method. Unfortunately, the ByteArray containing the flv data must be first correclty encoded for php to read it. I figured this out from the example in the net where it does the same thing only that it is only sending a JPEG ByteArray instead of a FLV format using the JPEGENCODER.
Is there any existing class like the JpegEncoder for FLV format or any Video formats? Or any work around like creating the encoder my self?
here is my current code to send the ByteArray
//send byteArray to a php script
var request:URLRequest = new URLRequest(url);
request.method = URLRequestMethod.POST;

Flex :: Resizing Image From A Decoded ByteArray?
Oct 20, 2009I am trying to display a bytearray as a resized image. The Image is displaying correctly, but the sizing is off. Let me explain.
First I have the image data encoded so I need to decode the image data
// Instantiate decoder
var decoder:Base64Decoder = new Base64Decoder();
// Decode image data
[Code]....
This works. The image is displayed correctly. However, if I hardcode the image (img) height the resized image is shown correctly, but within a box with the original image's dimensions.
For example, if the original image has a height of 300px and a width of 200px and the img.height property is set to 75; the resized image with height of 75 is shown correctly. But the resized image is shown in the upper left corner of the img container that is still set to a height of 300px and a width of 200px. Why does it do that? And what is the fix?
The best way to illustrate the problem is by placing the image inside a VBox and show the borders of the VBox. From the code block above, if I change the image height and set the image to maintain aspect ratio (which by default is set to true but I add it here for completeness). the problem becomes clear.
// Display image
var img:Image = new Image();
img.height = 75; // Hardcode image height (thumbnail)
img.maintainAspectRatio = true;

Flex :: Have Image Bind To Bytearray Rather Than Bitmapasset Or Bitmap
Feb 15, 2011I have an object that stores the compressed ByteArray version of an image (jpg or png). I want to keep it that way as the bytearray is about 30x smaller than the Bitmap it creates. The problem I run into is when I want to bind an image to this byte array. I can't really bind it to bytearray, because it requires a BitmapAsset as a source. Is there a way I can load a BitmapAsset from a bytearray but still bind to the bytearray when a new image is available?

May 11, 2010I'm currently working on a small project. The user is supposed to draw/do a puzzle within flash, and also fill out a form with his details and comments.
When clicking the send-button, the image should be sent along with the form as an email.
I already know how to send the image as an email via php, and I know how to send a form as an email via php, BUT - I can't seem to do it together.
I've googled a bit and I found out that I cannot pass both the bytearray (from the image) and the form-data as URLVariables at the same time.
One way I got it to work is by passing the values from the form-data as a part of the URLRequest (and then use $_GET in the .php-file), but this has limitations as it can only pass 100 characters. As the user should be able to comment on his work, using GET with its limitations isn't an option.
Php :: Send An Actionscript ByteArray As A POST Variable (within Facebook)
Dec 18, 2010I would like to use Flash to send a ByteArray (of a PNG image) to a php file, in a facebook application. Is there a way to do this by sending the ByteArray as just one POST variable instead of as the entirety of the POST data?
There was a nearly identical question here: How can I send a ByteArray (from Flash) and some form data to php? but the problem is different; instead of smuggling other variables in other parts of the request, the image itself has to be sent as just a variable because Facebook commandeers the post data and puts in its own junk.
If not, can I send the image in some form other than a byteArray?
ActionScript 3.0 :: Send ByteArray To Flash Without Using Php_amf Extension
Oct 3, 2010I'm working on a Flash tool that needs to send some data in the form of a flash.utils.ByteArray instance to PHP (amfphp service class) and get that data back from the amfphp service as flash.utils.ByteArray instance. Now I can do all of these with the php_amf extension enabled on the local WAMP server. And the tool works fine. But how can I achieve this without the php_amf extension? I'm deploying on a shared hosting server and I don't have access to the php.ini and also the dl() function of PHP is disabled for security reason. With the extension disabled, I can send the ByteArray instance to PHP and save the data to DB. But the problem arises when I try to retrieve the data from DB, create a ByteArray instance (amfphp helper class) with the data and send back to Flash. I'm guessing here that proper AMF message is not being constructed because of the absence of the php_amf extension.
View 1 RepliesPhp :: Send More Than One 'stream' Of Jpeg ByteArray Data In A Single URLRequest And Output 2 Images?
Jan 25, 2011I have an AS3 swf which users can upload jpg images to my EC2 instances which sit behind and Elastic Load Balancer. The jpg images are converted into bytearray data and sent using URLLoader.load(URLRequest)I make 2 calls when uploading, one to upload a large version, then another to upload a thumbnail version. A PHP script to which the bytearray data is uploaded converts this to a file using file_put_contents($destination,$GLOBALS["HTTP_RAW_POST_DATA"])Is it possible to combine these two requests into a single request which contains both the bytearray data for the large and thumbnail images and 'split' the HTTP_RAW_POST_DATA to create 2 files at the server. This would be better than uploading the bytearray for the large version then using something like ImageMagick to resize the resulting image into a thumbnail which I realise is another option.

View 1 RepliesRuby :: Image/ByteArray To SVG Conversion?
Nov 12, 2009I am wondering if it is possible to get a url to some image on google, say a square (jpg/png/gif), and process it into an SVG. Is this possible?
Right now I'm getting ByteArray data in Actionscript by making a URLRequest('image/on/google'), with dataFormat="binary". I don't think Actionscript could handle/do it, but maybe it could. I'm also good with Ruby, so perhaps is this possible with Ruby?
If so, any sample code/libraries to get started?
I guess another way to ask it is, how do I convert a Bitmap to a set of Vector Paths like Adobe Illustrator does?

ActionScript 3.0 :: Getting Image Dimensions From The ByteArray
Aug 19, 2011I have been searching in forums and I couldn't find an answer so I thought maybe I should ask.
I wrote a script that allows user to select a local file, which gets resized if it exceeds the width/height limits I specified, and finally this file gets uploaded to the server.
In documentation it writes the same max sizes for BitmapData and Loader:
Quote:
In AIR 1.5 and Flash Player 10, the maximum size for a loaded image is 8,191 pixels in width or height, and the total number of pixels cannot exceed 16,777,215 pixels. (So, if a loaded image is 8,191 pixels wide, it can only be 2,048 pixels high.) In Flash Player 9 and earlier and AIR 1.1 and earlier, the limitation is 2,880 pixels in height and 2,880 pixels in width.
So what I need is to check the file size (width and height) before I attempt to load the bytes of the file into a loader. I'm limited to the ByteArray that I get by the load of the file via a FileReference instance.
Has anybody seen a source where you can get that data out of a ByteArray prior to loading it into a DisplayObject?
ActionScript 3.0 :: ByteArray To Server-side Image
May 22, 2009I'm capturing an image from an swf and transmitting it as a byteArray to a php file. Everything seems OK in capturing and sending the data but the final image doesn't display and says it is corrupt.
I'm not sure if i need to do something to the byteArray or if there is something wrong on the php side that is causing the error?
I'm using stuff I've found on other posts and haven't tried JPGEncoder yet which is mentioned in some of those posts and examples. I thought it would be simple enough if it was just a getPixels() and wouldn't need JPGEncoder.
here is my AS3 code:

ActionScript 3.0 :: Capturing An Image BitMapData In ByteArray
Dec 19, 2010I'm trying to grab the BitMapData from an Image, convert it to JPG, and send it to a server where it will be written to a file. It "looks" like it works, the resulting .jpg is the right size and displays in an image viewer, but there is no picture... just an off-white background. Here's a code snippet:
imgTemp.addEventListener(FlexEvent.UPDATE_COMPLETE , imageLoadedHandler);
...
private function imageLoadedHandler(event:Event):void {
if (imgTemp.width == 0) return;
[Code].....
Then send "ba" to the server where it's written as a .jpg.
The data "looks" right when I receive it on the server, correct length, bits look the same.
ActionScript 3.0 :: Converting Image Into A Readable ByteArray?
Jul 19, 2011I'm trying to read out some BitMapData into some kind of readable output.
Reason for this is I'd like to trace out the ByteArray and hopefully cut and paste its details into an .as file and then compare it against another BitMapData Object or byteArray that is generated within the app.
Basically I want to compare differences between the two and report back how many pixels or something are different.
It might seem like a strange or approach.
I can create a BitMapData Object, it traces back as [object BitMapData] - so I thought awesome just loop through the Object... But looping through the Object traces nothing at all back out.
So I tried to create a ByteArray and then convert that to a string, but all I get is wierd 'y' chars with two dots on the top of the char.
I've left some code below,
Code:
public function GetAndCompareBitmapData(target:DisplayObject) {
var bd:BitmapData=new BitmapData(target.width,target.height);
trace("bitmapData "+ bd); // trace [object BitMapData]

ActionScript 3.0 :: Upload ByteArray As Image To Server?
Mar 7, 2012I'm trying to snap a bitmap image from within my application, and upload the bytes directly to my server to save as an image. I'm trying to same three separate images, three different sizes. I am able to do it twice, but as soon as it tries to save the third image, it throws a 2176 error...
ActionScript Code:
var url:String = 'myUploadURL';
var request:URLRequest = new URLRequest(url);
request.contentType = 'multipart/form-data';
[Code]....
I've tried a 3rd party class which wraps the byteArray and sends the data. This too works the first two but not the third.
Is it because I start by calling a function on mouseClick, that snaps the first bitmap then uploads, then snaps the second and uploads, then snaps the third and by the time it tries to upload, Flash assumes the function is 'too far away' from the mouseClick, and doesn't think it comes from user interactivity?
