Put bone in the center of image

Houpo

I want my cog animation to rotate smoothly, but the position of the bone is not exactly at the centre of the image, so the result is a bit jiggle.
Is there any feature to snap a bone at the center of the image?

There isn't, but you can type a transform value. Region attachments are positioned using their center, so you just need to give a bone the same world coordinates as the region attachment: click a region attachment, make sure World axes are selected, copy the X translation value, click a bone, paste the X translation value, repeat for Y.
