Hi
I still has no way to build smooth animation. I just want to display a small png fly from left to right, but the screen is blinking. Anyone has a working example?
thanks

need more information then the screen is just blinking.

is the PNG an animated PNG file?
Or you simply want to move as in slide an image across the screen?
