Fading Large Bitmaps

[Thoe99]

I have a background bitmap that I made it fading to nothing if you leave that page. Seems like tweening it really bogs the flash file, making it fade chunky. Is there a way to fade it programmatically and have it fade smoothly at the same time?

My guess is that you'd still be using alpha and that's what's hard on the processor! Regards,

I was just wondering if programming it made a difference or not, since it does on many other aspects of the program. It doesn't on alpha?

If you're fading to nothing but black or white (i.e. there's no image underneath the one you're fading) you can tween the _brightness of the image rather than the _alpha which is a lot less work for the processor and so looks smoother.

Otherwise to fade to any other solid colour you can tween to a tint from the advanced option in the 'color' dropdown. Slainte

Hmm...the reason I'm fading this thing is because I have a bitmap underneath it. I figure fading a black object above it will be more friendly, which it does work better.
