stretch - offset in pixel

[laurentl]

stretch offset uses relative size in fraction of stretched size.
I want to stretch between two side buttons which are constant in pixel size so that relative size business doesn't work.
How do I do that ?

(it's like stretching between two anchors)

Write a custom script.

No, really

UIStretch won't work for what you are trying to do. You need to write a custom script that will calculate the distance between A and B, then position the object in the middle and set the scale to be that value (assuming central pivot).
