AS3 Bitmap Smoothing in Flash

August 28th, 2008 · 1 Comment

This is just a small experiment on Flash bitmap smoothing in ActionScript 3. A small piece of codes can be sometimes too hard if one does not know how to write it properly. You may try the below sample and adapt it for your own Flash projects.

PLAIN TEXT
Actionscript:
  1. var flashmo_bm:Bitmap = new Bitmap();
  2. var flashmo_mc:MovieClip = new MovieClip();
  3. var pic_request:URLRequest = new URLRequest(“flashmo_400×300_02.jpg”);
  4. var pic_loader:Loader = new Loader();pic_loader.load(pic_request);
  5. pic_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, on_loaded);
  6. pic_loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, on_progress);
  7. flashmo_info.text = “”;function on_loaded(e:Event):void
  8. {
  9. flashmo_bm = Bitmap(pic_loader.content);
  10. flashmo_bm.x = - flashmo_bm.width * 0.5;
  11. flashmo_bm.y = - flashmo_bm.height * 0.5;
  12. flashmo_bm.smoothing = true;
  13.  
  14. flashmo_mc.addChild(flashmo_bm);
  15. flashmo_mc.x = stage.stageWidth * 0.5;
  16. flashmo_mc.y = stage.stageHeight * 0.5;
  17. flashmo_mc.buttonMode = true;
  18. stage.addChild(flashmo_mc);
  19.  
  20. flashmo_info.text = “Bitmap smoothing is “ + flashmo_bm.smoothing;
  21. flashmo_mc.addEventListener( MouseEvent.MOUSE_DOWN, activate );
  22. flashmo_mc.addEventListener( MouseEvent.CLICK, deactivate );
  23. toggle_button.addEventListener( MouseEvent.CLICK, toggle_smoothing );
  24. }
  25. function on_progress(e:ProgressEvent):void
  26. {
  27. var percent:Number = Math.round(e.bytesLoaded / e.bytesTotal * 100);
  28. flashmo_info.text = “Loading… “ + percent + “%”;
  29. }
  30. function activate(e:MouseEvent):void
  31. {
  32. this.addEventListener( Event.ENTER_FRAME, moving );
  33. }
  34. function deactivate(e:MouseEvent):void
  35. {
  36. this.removeEventListener( Event.ENTER_FRAME, moving );
  37. }
  38. function moving(e:Event):void
  39. {
  40. flashmo_mc.rotation = mouseX + stage.stageWidth;
  41. flashmo_mc.x = mouseX;
  42. flashmo_mc.y = mouseY;
  43. flashmo_mc.scaleX = flashmo_mc.scaleY = 0.003 * mouseY + 0.2;
  44. }
  45. function toggle_smoothing(e:MouseEvent):void
  46. {
  47. if( flashmo_bm.smoothing == true )
  48. flashmo_bm.smoothing = false;
  49. else
  50. flashmo_bm.smoothing = true;
  51. flashmo_info.text = “Bitmap smoothing is “ + flashmo_bm.smoothing;
  52. }

    Hi, in one of ur blog comments I read
    “Liam, links will not work in your computer due to Flash Player security policy. Link will be working if you run on your web server or Local Host”

    I assume you are talking about links inside externally loaded swfs.
    As I am having the same problem , it works on my local system but not when deployed.

    Can you tell me how to fix this? kindly mail me:)
