  1. Found it ! It was indeed the cropping function & matrix : old code var icf:Bitmap = crop(t.x,t.y,t.width,t.height,ic); new code var icf:Bitmap = crop(t.x,t.y,t.width,t.height,h);
  2. Hello petervee, thanks for replying! The problem is not related to the export as PNG function : When I export I'm getting a transparent triangle. There is a difference in positioning between the preview version ("bt3"-button) and the exported PNG ("bt2"-button). I think greensock is right and it has to do with the matrix. Any help would be much appreciated
  3. Thanks for the reply, I'll have a try. Looks like heavy stuff tho
  4. Hello, I'm not experienced in AS3 and cannot make this work, can somebody see what I'm doing wrong ? The idea : - User uploads an image - Image is loaded into a container which is assigned to TransformManager - A triangular mask is applied to the image container - The result is the transformed image in triangular form which is exported The problems : - The transformation is not taken into account when exported - There's a difference in positioning between the preview version and the final image : crop function ? The code : stop(); import com.greensock.transform.TransformManager; import com.greensock.events.TransformEvent; import com.adobe.images.JPGEncoder; import com.adobe.images.PNGEncoder; import com.adobe.serialization.json.JSON; import flash.display.*; import flash.events.*; import flash.net.*; import flash.text.*; import flash.ui.*; import flash.utils.*; import mx.utils.Base64Encoder; // place holder var h:MovieClip = new MovieClip(); addChild(h); h.x = 0; h.y = 0; // place image container var ic:MovieClip = new MovieClip(); h.addChild(ic); // triangle movie var tb:triangle_base = new triangle_base(); addChild(tb); tb.x = (stage.stageWidth - tb.width) / 2; tb.y = (stage.stageHeight - tb.height) / 2; // mask triangle movie var t:triangle = new triangle(); h.addChild(t); t.x = (stage.stageWidth - t.width) / 2; t.y = (stage.stageHeight - t.height) / 2; t.visible = false; // loading_layer movie var ll:loading_layer = new loading_layer(); addChild(ll); ll.x = 0; ll.y = 0; // loading_symbol movie var ls:loading_symbol = new loading_symbol(); addChild(ls); ls.x = (stage.stageWidth - ls.width) / 2; ls.y = ((stage.stageHeight - 40) - ls.height) / 2; // create loader var il:Loader; function loadImage(url:String):void { il = new Loader(); il.load(new URLRequest(url)); il.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, imageLoading); il.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded); } // get variable var FlashVars:Object = LoaderInfo(this.loaderInfo).parameters; var theVariableName:String; var theVariableValue:String; for (theVariableName in FlashVars) { theVariableValue = String(FlashVars[theVariableName]); if (theVariableName == "treat") { loadImage("upload/2-import/"+theVariableValue); resptxt.text = theVariableValue; } } // load process function imageLoaded(e:Event):void { // load and place bitmap into container var bm:Bitmap = Bitmap(il.content); bm.smoothing = true; // position image container ic.x = (stage.stageWidth - bm.width) / 2; ic.y = (stage.stageHeight - bm.height) / 2; ic.addChild(il); // activate transform on image var manager:TransformManager = new TransformManager({targetObjects:[ic], bounds:new Rectangle(0, 0, 800, 600), constrainScale:true, scaleFromCenter:true, arrowKeysMove:true, forceSelectionToFront: false}); ll.visible = false; ls.visible = false; } function imageLoading(e:ProgressEvent):void { // download progress } // redirect functions function goto1(url) { navigateToURL(new URLRequest(url),"_self"); } function goto2(url) { setInterval(goto1(url),5000); } // button actions function bt1Click(evt:MouseEvent):void { goto1("http://3pm.3suisses-game.com"); } function bt2Click(evt:MouseEvent):void { ll.alpha = .5; ll.visible = true; ls.visible = true; tb.visible = false; t.visible = true; ic.mask = t; var icf:Bitmap = crop(t.x,t.y,t.width,t.height,ic); var bmpd:BitmapData = new BitmapData(t.width, t.height, true, 0x00000000); bmpd.draw(icf); var imageFile:ByteArray = PNGEncoder.encode(bmpd); var base64:Base64Encoder = new Base64Encoder(); base64.encodeBytes(imageFile); var imageFileName:String = resptxt.text; var loader:URLLoader = new URLLoader(); var url:String = "saveimage.php"; var req:URLRequest = new URLRequest(url); req.method = URLRequestMethod.POST; var pngdata:URLVariables = new URLVariables(); pngdata.fileData=base64; pngdata.fileName=imageFileName; req.data = pngdata; loader.addEventListener(Event.COMPLETE, bt2Complete); loader.load(req); } function bt2Complete(event:Event): void { // tb.visible = true; // ic.mask = null; // t.visible = false; goto1("result.php?name="+resptxt.text); } function bt3Down (event:Event):void { tb.visible = false; t.visible = true; ic.mask = t; } function bt3Up (event:Event):void { tb.visible = true; t.visible = false; ic.mask = null; } // crop image function crop(_x:Number, _y:Number, _width:Number, _height:Number, displayObject:DisplayObject = null):Bitmap { var cropArea:Rectangle = new Rectangle(0, 0, _width, _height); var croppedBitmap:Bitmap = new Bitmap(new BitmapData(_width, _height, true, 0x00000000), PixelSnapping.ALWAYS, true); croppedBitmap.bitmapData.draw((displayObject!=null) ? displayObject : stage, new Matrix(1, 0, 0, 1, -_x, -_y) , null, null, cropArea, true); return croppedBitmap; } bt1.addEventListener(MouseEvent.CLICK, bt1Click); bt2.addEventListener(MouseEvent.CLICK, bt2Click); bt3.addEventListener(MouseEvent.MOUSE_DOWN, bt3Down); bt3.addEventListener(MouseEvent.MOUSE_UP, bt3Up); Any ideas are very welcome ! Thanks in advance
