I'm using PowerPoint for a presentation (I know that other tools may be better, but not in this case).
In a transition between two slides, I've to zoom part of an image (which is a simple tree structure, with a root and two children nodes/leaves) and pass to the next slide, like if the next slide extends the concept of one leaf.
How is it possible to do that?
I tried with growing the tree image, setting the leaf to the center/middle, but I'd prefer using a better technique (a transition instead of a group of animations) or a proper plugin.
I have to agree with lawndartcatcher. There's not going to be a good way of doing this without a good amount of custom animation.
They quick 2 minutes job is to create copies of your node and scale them up, then have them zoom into the slide one after the other until it takes up however much of the slide you want, and then to transition to your next slide.
The easier alternative of course is to use something other than powerPoint, but as you've mentioned, that's not an option.
