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.
