Hi
the reason I use your method is to snap my object to edge of my view in coordinate container with fix mode. I recreate google map layout with this successfully.
This make me to simulate anchor mode of vision.
But as I told and if you test it, you see the left : 13 px doesn’t offset object from left with 13px. On the other hand right: 13px works correctly.
Can you recreate this image?
The viewCanvas has same problem.
