Hi, Here is my code....
<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; styleName="plain"> <mx:Script> <![CDATA[ import mx.graphics.codec.PNGEncoder; import mx.rpc.events.ResultEvent; private var isDrawing:Boolean=false; private var x1:int; private var y1:int; private var x2:int; private var y2:int; private var drawColor:uint; private function doErase():void { canvas.graphics.clear(); } private function doMouseDown():void { x1 = canvas.mouseX; y1 = canvas.mouseY; isDrawing = true; } private function doMouseMove():void { x2 = canvas.mouseX; y2 = canvas.mouseY; if (isDrawing) { canvas.graphics.lineStyle(2, drawColor); canvas.graphics.moveTo(x1, y1); canvas.graphics.lineTo(x2, y2); x1 = x2; y1 = y2; } } private function doMouseUp():void { isDrawing = false; } private function doSave():void { var PNGEnc:PNGEncoder=new PNGEncoder(); var bd:BitmapData = new BitmapData(canvas.width,canvas.height); bd.draw(canvas); var ba:ByteArray = PNGEnc.encode(bd); } ]]> </mx:Script> <mx:Panel title="FlexPaint"> <mx:Canvas id="canvas" width="300" height="300" horizontalScrollPolicy="off" verticalScrollPolicy="off" mouseDown="doMouseDown()" mouseMove="doMouseMove()" mouseUp="doMouseUp()"/> <mx:ControlBar> <mx:ColorPicker change="drawColor = event.target.selectedColor"/> <mx:Button label="Erase" click="doErase()"/> <mx:Button label="Save Image" click="doSave()"/> </mx:ControlBar> </mx:Panel> </mx:Application> This is actually a sample code.... Actually the user can draw an image in the canvas by moving the mouse...Once after drawing the equation if he clicks on " Save Image " I call a function called doSave() where i convert it canvas data in to a bitmap and then convert it into a byte array using the PNGEncoder... Now i need a jsp file to capture the byte array decode it back store it in a file and save it in server.. the latter part storing it in server i will see to it.. What i need is 1) To pass the byte array from flex to jsp. 2)Capture it in jsp decode it and store it in a file...
