= =||| I am confused about example of reflection padding_mode…
In doc:
padding_mode="reflection" : use values at locations reflected by the border for out-of-bound grid locations. For location far away from the border, it will keep being reflected until becoming in bound, e.g., (normalized) pixel location x = -3.5 reflects by border -1 and becomes x' = 1.5 , then reflects by border 1 and becomes x'' = -0.5 .
but why reflects by border1 becomes x'' = -0.5  not x'' = 0.5?
if x = 6.5,it does mean that x' = -4.5,x'' = 2.5,x''' = -0.5 or x''' = 0.5?
Looking forward to your reply and thx for your help
