Hey there,

I'm pretty new to Revolution Enterprise and I've come across a problem creating some kind of Coverflow. When I'm moving a group of groups of images I have noticed some kind of flickering on the images. The group itself moves smoothely but the images seem to have something like jumping blendLevels or so. Using AnimationEngine doesn't solve the problem either... I've tried to use different moveSpeeds and when I move the group in 1 second intervals I see a flicker on 2 moves, the third one seems less flickery and the fourth move is clean. Then it starts again... lockmoves don't work either.

Hope someone has a solution to this.

Hi doubleB,

what is the alwaysBuffer of the images set to?

Cheers,

Hi Malte,

thanks for writing.

The alwaysBuffer of the images was set to default (false I think).
I've tried to set the alwaysBuffer of all images to true and to false, neither one improves to flickering problem.

Setting the alwaysBuffer of the stack to true doesn't help either..

Hey there,

seems like I've discovered the root of the problem. The flickering images are made of diagonal stripes
(like this one here:
(not my work))
where the width of 1 stripe is 1 pixel.
So if I increase the width of the stripes the flickering is almost completely gone.
Has anyone a good explanation for this?
I've tried to set the syncRate to everything between 5 and 25 but that doesn't solve the problem either.
Are there other settings I might wanna try? Like antialiasing the images or something (isn't possible, is it?)

The strange thing that bothers me is moving the image in 1 second intervalls like mentioned in my 1st post.
Can anyone tell me something about that?

Greetings BB
