I have a quest,I want to save the mapcontrol(arcgis map control) to a
Image,Then send the Image to the webserver.
below the is code:
+++++++++++++++++++++++++++++++++++++++++++++
var width:Number  = map.width;
var height:Number  = map.height;
var bitmapData:BitmapData = new BitmapData(width, height);
bitmapData.draw(mapcontainer,new Matrix());	

var file:FileReference = new FileReference();
var jpg:JPEGEncoder = new JPEGEncoder();
var ba:ByteArray = jpg.encode(bitmapData);

var urlrequest: URLRequest = new URLRequest(uploadImgUrl + "?id="+appId);
urlrequest.method = URLRequestMethod.POST;
urlrequest.data = ba;
urlrequest.contentType = "application/octet-stream";
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE,finishCaptureUpload);
loader.load(urlrequest);
