Collapse transformation height and width

[Ignacio5FD4]

Hello everyone.
How can i get the width and height from a precomp with collapse transformation activated? sourcerectattime only show the width and height from full composition.
PD: my english is not so good.

I'm not clear what you are asking. The properties as such don't change and the comp dimensions are the same with and without CR/ CT. If you need to retrieve info from within such a setup, then other methods are required, but you realyl have to provide an explanation of what you are actually trying to do.

Thank you for your time, I hope my explanation is clear.

It might help to think of Collapse Transformations like this:

Imagine you have a Tardis, that's much bigger on the inside (that's your precomp).  When Collapse Transformations is on, it effectively opening the door to the Tardis.  From the outside, all the dimensions are the same, even though you can see it is much bigger.

You'd like to know the bigger dimensions but AE is only able to tell you the door's size.  What you can do though is move the precomp's timeline out from the same panel so you can see both timelines, then use the pickwhip to pass details from the precomp to the main comp for you to use.

I'm still not sure what you are asking. You can simply multiply the values with the scale to obtain the correct values. If there is anything more going on, you need to tell us.

The problem he is facing here is that by setting collapse transformation for comp A in the comp B, he actually sees "reduced boundary" of that A inside B (because empty areas are dismissed in GUI). 

However, sourceRect still returns default comp A size while author expects it should be "only bounding of assets".

It seems that the best way would be picking comps A left element left top edge (white triangle corner), as well as paragraph of text itself, and calculating it this way all together (keeping in mind scaling must be taken into account as well). In other words - no easy way to achieve.
 
Most likely author wants to have this information to re-position multiple paragraphs with identical gap in-between, while paragraph heights changes.
