The corners of a tag are returned differently than the old version!

[laygond]

Just a heads-up!
For a detected tag (with no rotation), the order of the corners are wrapped counter-clock wise around the tag starting from the left-bottom corner. For example if tag has corners ABCD placed in the following way.

A	D
B	C

THIS VERSION:

for r in results:
    (ptB, ptC, ptD, ptA) = r.corners

OLD APRILTAG:

for r in results:
    (ptA, ptD, ptC, ptB) = r.corners
