I am building a form builder in Flex 4.5. For that I need help regarding uploading image at runtime such that any user can just simply place cursor on particular location on image and is able to upload any image from the local file system.

View 1 RepliesI'm using Flex 4.5 in a Mobile air for android application. So, Using the Camera/Camera roll [URL]I want to do a simple upload using amfphp Note: Since this is how you get pictures on devices, i cant use the filreference because it wants you to get the pictures using "browse" which cant be done on android or ios My plan is, after I select a picture or capture one with the camera, in the event I can get the local url to the picture that was taken like this:
[URL]
I'm putting this in the imageURL var (i'm assuming i should make it into a byte array to transfer it, im not exactly sure this is my first time making something like this)Here's how i'm taking that image, making it into a byte array, and using amfphp to send the upload to the server:
protected function upload_btn_clickHandler(event:MouseEvent):void
{
var request:URLRequest = new URLRequest(imageURL);
var urlLoader:URLLoader = new URLLoader(request);
[code]....
But i'm getting an error NetConnection.Call.BadVersion.This is the first time im trying something like this so im not even really sure if im going about it right. All the examples I find online go about using the fileReference class, but that seems to require me to use the "browse" method, and im on a mobile application that uses the camera and camera roll to grab pictures off the device, and im not sure how to incorporate that into the fileref class. I figured i could just get the byte array and send it to php myself and it should be just fine.
Using org.as3commons.reflect I can look-up the class name, and instantiate a class at runtime.I also have (non-working) code which invokes a method. However, I really want to set a property value. I'm not sure if properties are realized as methods internally in Flex.I have a Metadata class which stores 3 pieces of information: name, value, and type (all are strings).I want to be able to loop through an Array of Metadata objects and set the corresponding properties on the instantiated class.[code]I realize that I have to declare a dummy variable of the type I was to instantiate, or use the -inculde compiler directive. An unfortunate drawback of Flex.Also, right now there's code to account for typecasting the value to it's specified type.
View 1 RepliesI need to dynamically bind properties of components created at runtime. In this particular case please assume I need to use bindProperty. I don't quite understand why the following simplistic test is failing (see code). When I click the button, the label text does not change.
I realize that there are simpler ways to go about this particular example using traditional non-dynamic binding, but I need to understand it in terms of using bindProperty.

View 2 RepliesIn Flex, how to assign swf as image source at runtime, not embedding it.[Bindable] public var myImg:String;<mx:Image id="intImg" source="{myImg}" width="96%" height="96%" />In my application, I fetch image url dynamically from a web service call, and assign it to "myImg". But until I don't get the response from the web service call, I want to show a loader swf in image control above. I assigned something like:myImg = "assets/AS3.swf";and the path of swf is correct, but it doesn't show up.UPDATE:The code I've shown above works perfectly in a Flex 3 app but the swf does not show up in a Flex 4 app. Is it because Image control has dropped the support for swf in Flex 4 ?
View 3 RepliesI have an image component:
Code:
<mx:Image x="6" y="8" id="image" />
I'm allowing the user to choose some image and load it at runtime.
Code:
image.source = "../images/temp.jpg";
Why doesn't this do anything? I just see the little error icon like you see on a website when an image cannot be found. But I definitely have temp.jpg.
After browsing for the images, and selecting them. How can I display a preview of the image in the datagrid? I am able to display the file name, file size, but was unable to display the image. Below are the codes I have written, it is not a complete code but just enough to make it understandable.
// variables used
var list:Array = new Array();
var listDP:Array = new Array();

As far as I know, what I ask here isn't possible, but I thought I'd ask anyway in case I'm missing something.
Suppose you want to let users upload JPG images, and these images are scaled into smaller icons and the original images are always discarded and never required again. Is there any way that would commonly work in most modern browsers that would let the user select a single image on their hard drive, have that LOCALLY turned into a thumbnail and upload the created thumbnail to a server?
In a case where the server just needs a small image, it would be wasteful both in user time and server resources to proceed uploading the whole image, only to immediately discard it. It would be much better to just scale it on the client.
I can imagine three options. Just plain HTML/Javascript, using Flash or using Java. If this were possible with Flash, that would seem like the best option. But reading flash.net.FileReference documentation, it seems that you can upload a file from the HD yes, but you cannot look inside the file you are uploading. On the other hand, if you enable "can access local files" in Flash publishing options, it seems that you can then no longer access the net, so that doesn't work.
With HTML/Javascript, it is possible to load images and display them on a <canvas>, but if you try to access the pixels of these images, you get security violations, so that doesn't seem to work.
Java I hesitate to use, because only 96.52% of my users have it installed, and the file upload dialogs I have seen implemented in Java (at Facebook for example) have not worked well (unresponsive interface). I wonder though if Java is the only thing allowing resizing images from local HD?
I made a dynamic text field inside of a movie clip. I then dragged the scroll bar component over, and it worked, yeah! But they Im uploading a .txt file dynamically through the .swf The text displays and is selectable but it does not scroll. The scroll bar is there but doesn't work.

I asked a similar question before but didnt get a definite answer! Basically I just want to know if its possible to have a standalone SWF file which allows the user to browse there computer and load an image into the SWF to view it (in AS2)? Ive researched this FileReference class but it seems that requires servers and what not. I only want to upload the image to the SWF, not to an external server?
View 2 RepliesI want to give the users the ability to set the background color or choose image to make it background (Tile, Center and Strentch). I tried couple of things with no luck such as trying to chaing a Skin object and assign it.and tried something like:
FlexGlobals.topLevelApplication.setStyle("backgroundColor",uint(chosenColor));
I'm looking for some flash based plug-in which allows me to display an image as soon as the user selects it in the file dialog.I looked at swfupload but couldn't find any way to display the image selected.. no handle on file path or contents as far as I could find.
View 1 RepliesFor the past few hours I've been trying to figure out a way to add a watermark to an image file before uploading it using the FileReference.upload(); method. The uploading works already. I just have to figure out how to get a small watermark (PNG image with alpha-transparency) on the lower right of the image file. Another thing is, I don't want to modify the source file. I just want to add the watermark on upload.
What approach would you recommend for this type of setup? I also can't seem to find any pre-made classes already that I can use for this certain thing. Is this not a very common task? And no I can't use server-side (PHP) to do the watermarking because I'm communicating directly to a service's API, not through my server.
I am writing an app for android devices, it uses the CameraRoll class to retreive images from the gallery. It then catches the raw bytearray data and encodes it into a base64 string, then sends the string via httppost to a server that decodes the string and saves the file.Every part of this is fine except one detail, the images are corrupt when they are saved on the server. Except one thing that makes things weirder, when I load these corrupt jpg images into a flash app they work just fine.Previously I have made apps that uses the Camera class to take photos in the app, and this works fine, the reason I am using cameraroll is because I want to be able to get high quality images, which is not possible using the regular camera -> bitmapdata.draw -> jpegencode -> send method.The code is basically thi

i am currently creating a software, i need to upload images form my HDD to server. i can do this with FileReference Object. with this code i can select file.
var f:FileReference;
f.browse(); // for selecting file (object)
and after that i will send that FileReference object to a PHP file and i upload via that PHP file.
but i want to upload file without using FileReference Class i am using File Class on Air 1.0 on Flash, and that class can provide full url of image from my HDD like: D:My Documentsimage01.jpg
there is any way to upload this file on my HDD to server without using browse() class for selecting file on Flash with PHP?
or is there one way to convert File Class (AIR) to FileReference?

I need to upload an image to a SWF, however I can't use ActionScript for it because the client wants drag-and-drop capability. I figure that I can make the upload button cause a popup, where there is JavaScript for drag-and-drop. The SWF allows for some photo manipulation, so the image needs to be uploaded, and be in the SWF for that use. how can I make that image accessible to the SWF file?
View 1 RepliesI've developed a Flash quiz app for facebook, which calls for a php script silently upon completion. The php script's function is to generate an image from the POST data sent by the flash, and then post it to the user's wall.That would be all neat and dandy, but for some reason the image never gets uploaded, probably because when i call it, it's like [URL] and the facebook SDK script inside gets an Oauth error, probably because it is not embedded in their canvas.
If I'd like to have my php script generate an image and upload it to the fb wall, then how should I call it from the flash?This is the AS2 code I'm using currently:
callRemoteFile = function(ourVariable:Number) {
var result_lv:LoadVars = new LoadVars();
result_lv.onLoad = function(success:Boolean) {

Fatal error: Uncaught OAuthException: Invalid OAuth access token signature. thrown in /home/a01223445/public_html/appfolder/base_facebook.php on line 1039
If I view the same php through facebook canvas it works perfectly. My problem is: The canvas will show the flash and I want the php to silently be evaluated while the flash is running.

var jpgSource:BitmapData = new BitmapData (container_mc.width, container_mc.height);
jpgSource.draw(container_mc);

And how can i say to image_mc to load the jpeg at the center of image_mc's axis. So that when i flip the image, the image will flip vertically at the center?
is it possible to upload an image from local computer to online flash application, but without actual uploading it to a server, just in memory. Need to load picture, make some manipulations, print it from flash and forget.thrashing the server with loads of photos is worst scenario.
