Flex Mobile - Resize Image and send to server with blazeds

[chris_d_k <ck...@christiankiefer.de>]

I have taken a photo with the camera roll and I am able to display it :

        private function imageSelected(e:MediaEvent):void
        {
            var mediaPromise:MediaPromise = e.data;
            this.mpLoader = new Loader();
            this.mpLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,
onMediaPromiseLoaded);
            this.mpLoader.addEventListener(IOErrorEvent.IO_ERROR,
onMediaPromiseLoadError);
            this.mpLoader.loadFilePromise(mediaPromise);
        }

        private function onMediaPromiseLoaded(e:Event):void
        {
            var mpLoaderInfo:LoaderInfo = e.target as LoaderInfo;
            mpLoaderInfo.removeEventListener(Event.COMPLETE,
onMediaPromiseLoaded);
            mpLoaderInfo.loader.removeEventListener(IOErrorEvent.IO_ERROR,
onMediaPromiseLoadError);

            imageDisplay.width = CONTENT_WIDTH;
            imageDisplay.height = (CONTENT_WIDTH / mpLoader.width) *
mpLoader.height;
            imageDisplay.source = mpLoaderInfo.loader;
        }

I have a button and when I press it I want to send the image scaled
(proportionally to 1000px) to the server (we use BlazeDS). What's the best
way to achive this?

Hi Chris,

well I use a similar approach, but do the resizing on the server. But regarding your question towards BlazeDS. I am using this in production by storing the image data in ByteArrays and using these to sent stuff back to the server. That's working fine for my part.

I've done the client-side resizing using this approach:

Had worked fine, so just give it a try.

Chris
