Scanner line effect

Whats up you all, how are you doing today?
ok a question have come up to my mind and it the Scanner effect.
you know that effect that a line pass by and as it pass it goes revealing a picture or something under it?
like if it was a scanner.
Well if you know how to do it, can you give me some suggestions or help on how to do it?

thank you very much.

I think you might want to look into using a masking layer.

yep - masking it is the easiest way

Can you use gif or something to make scanline effects in Flash? As a mask.

You could, but I don't see where there would be a need to.

To make some trick looking text or something. What would it have to be a .gif or .png

You can import GIF, JPG and PNG into Flash. The GIF would retain it's transparency. The PNG would to, if the browser did. Moz flavors do this automagically, IE needs a bit of javascript to do PNG transparency correctly.

You lost me, you mean to display in the browser? param name=wmode value=transparent
I might try some mask effects. No any good examples anywhere?

I'm gettin a bit confused on this thread too. I'll just try to clarify what I was saying in regard to your last post.

The window mode (wmode) set to transparent allows a Flash presentation to display without a background. It doesn't work in Opera.

If you insert a transparent GIF into a Flash presentation, it will have it's transparency in Flash. This isn't effected by the wmode however. The GIF has a separate transparency.

PNG's also support transparency, but aren't universally supported like GIF's are (Mozilla browswers have support for PNG transparency, IE and Opera don't). If you insert a transparent PNG into a Flash presentation, the PNG will have transparency in Mozilla but not in IE or Opera.

IE can be made to support PNG transparency via javascript. If the javascript is present in the hosting HTML page, the PNG will be transparent within the Flash presentation. If the javascript isn't present, the PNG will not be transparent within the Flash presentation. This is true regardless of what the wmode is set to.

The wmode and the transparency of the images inserted in Flash (GIF or PNG) don't really have anything to do with each other.

I've created an example file that I hope addresses the original post. I've saved it as a Flash MX file. I've also set the wmode to transparent in the hosting HTML file. I have to apologize, the wmode does in fact work in the current version of Mozilla, I stated this incorrectly in my previous post which I've corrected. (It's been a loooooong day)
