Advanced image transition?

[Tomatos]

Hi there,
Can anyone help me concerning image transitions - I would like to know how the image transitions under the following link are made - press on "Katalog" and choose a photo in order to see the transition.

Has it been made with masking or...?

Hope anyone can help me out!

Thanks in advice,

Looks like they created some motion tweens and then set one of them to be the mask of the picture. You can dynamically set an existing movie clip as a mask by using the setMask method:

myPicture.setMask(myMaskClip);
{something like that - can't remember offhand}

Hope that helps...
