縮小した画像の描画が壊れる for Flash

画像を配置して縦横サイズを1%くらいに縮小して、座標0.0から遠ざかると描画がおかしくなるw

上から
① 横2950px / 縦4156px の画像を1%の大きさに縮小
② 横454px / 縦640px の画像を①のサイズに合わせて合わせて縮小
③ 縮小した①をBitmapData化してBitmapに再描画したもの

①〜③をTimerでx座標を移動していくと①と②の画像の表示が途中で壊れる


API リファレンスで「Flash Player 11 以降では、BitmapData オブジェクトのサイズの制限はなくなりました。」
って書いてあるけど②はそもそも2880pxもない。

You really make it seem so easy together with your presentation but I
in finding this matter to be really one thing which
I believe I would by no means understand. It kind of feels too complicated and very extensive for me.
I'm having a look forward in your subsequent post,
I'll attempt to get the hang of it!

After I initially left a comment I appear to have clicked on the
-Notify me when new comments are added- checkbox and now whenever a
comment is added I recieve 4 emails with the same
comment. Is there an easy method you can remove me from that service?
Many thanks!
