Bounding box and scripts
I’m looking for a way to access the bounding box of a layer from the extendscript toolkit. I want to create a center pivot script for after effects that could work with a mask, but from using the sourceRectAtTime method I’m only getting the coordinates of the layer size. If you draw a mask, and then select it, After Effects generates the bounding box that would be ideal to center the pivot to (It’s not a real center pivot, but it’s much better that what I’ve achieved with the sourceRectAtTime).
Does anybody know how to get to that property?
Thanks!

The only way I can think of would be to have the script temporarily apply sampleImage() expressions to determine the non-zero alpha extents of the layer. Messy, but do-able.

If the mask is open, or if it is not in ADD mode, it won’t work though.
Few times i also would have liked to access the mask bounding box/default anchor point too and it has no corresponding script property. Recalculating it from mask data is possible but requires some knowledge on bezier things.
This could be a new scripting feature request.
