‌Flipping Lock Coordinates #2

All of the lock coordinates for some trackers had been entered as read out of photoshop, which uses a left-handed coordinate system, which was convenient for that but undesirable otherwise. Here's the command to flip the coordinates to a conventional right-handed coordinates system.

for each tracker, make the tracker's y lock position 2047 - the tracker's y lock position.

where here the map was 2048 pixels high.

Or a different customer who used a left-handed coordinate system:

for each of the seed trackers, make the tracker's y seed position - the tracker's y seed position.
