    Moving to subpixels on Bitmaps

    Hey all,

    I've got a flash movie that's loading external images and panning left-to-right:

    http://www.upstatement.com/jared/pix.../homepage.html

    The problem is it seems to not render at the sub-pixel level causing that jerky motion. I checked Tweener and it is setting the x coordinates to decimals (eg -10.4, -10.6, -10.8...).

    Also, when I create the Bitmap object from the bitmap data I have smoothing set to true and the pixelSnapping set to 'never' any idea what else I could do to make this work? Right now I'm tweening a container sprite that holds the Bitmap -- should I apply the tranformation directly to the Bitmap object? --is there a filter or property of Tweener (or another tweening engine) that would help me out?

    Thanks,

    Jared

    ...One hack I've found is to add a small shift in the RotationY property which kicks on Flash's 3D rendering. It looks perfect, only problem is it will only work in Flash 10 -- any ideas for a hack that would provide a Flash 9 fix? (already tried the normal rotation property, but that doesn't do it)

    Try caching as bitmap or applying a filter (even one set to 0)...any chance you're loading the images from a different domain than the host page?

    Damn, just tried both to no avail. It'd make sense, right? But still results with the same jerky motion.

    The images are all same-domain with access to the BitmapData.

    Thanks for your ideas!
