you have to take the snap shot of your canvas first
<mx:Canvas id="mycanvas"/>
<mx:Button click="makebyteArray()"/>
/**
* for sending bitmap data on the server u have to make the ByteArray
of that
* bitmap data by png encoder
*/
private function makebyteArray():void
{
var objBitmapData:BitmapData = takeSnapshot(mycanvas);
var pngData:ByteArray = PNGEnc.encode(objBitmapData);
}
/**
* pass ur canvas reference to this function it will return the
bitmapdata.
*/
private function takeSnapshot(source:IBitmapDrawable):BitmapData
{
var imageBitmapData:BitmapData = ImageSnapshot.captureBitmapData
(source);
return imageBitmapData;
}
now you can send this pngdata to the server
