Did you try using Zoom effect which has originX and Y
properties? Resize effect always has 0,0 registration point and we
have Zoom effect where you can change the registration point as
well as resize the components.
I'm not sure the zoom effect would be appropriate for my
I want to being able to enlarge an object starting at 100%
and go up to 3x its current size, zoom goes from 0% to 100%. Also
it appears zoom scales the content as opposed to setting a new
width/height which means that lines strokes and fonts would look
distorted until zoomed to 100%
For now I'm using a Move effect in conjunction with Resize
effect to get the content to resize from its center.
