I have a group of features that are merged together into a spatial boundary (buffer of 25 feet) and I'd like to scale each group of features (lines included) from a known center point to a scale that would make each group more readable with labels. The number of groups varies from map to map. Each group is created as an inset map to a PDF. The brown diamond is where the center point is and the anchor point for my scaler. I wonder why the scaler transformer doesn't have a group by.
+22Just thinking out loud:
Could you aggregate the objects, apply the scaling and then de-aggregate?
Using Aggregator (has a group by), Scaler and DeAggregator.
+15calculate distance from centerpoint.
Use this to base your scaling on. Maybe use the desired fontsize as a modulus. (to prevent overlaps)
Either calculate scalevector per point (dx*cosAngle,dy*sin(angle)) or create lines form point to center (use a unconditional merge, or variablesetter/retriever to merge center to each pint) and scale those.
When having scaled liens, extract endpoint and place label.

Another option popped out my head by running each group through a worker transformer by group id and then scale in the worker workspace and then loop back to the next group until it's done.
