I found that when I let itk write the output as a file, it writes it in the inverse direction, i.e, if I try to just read and write an image doing nothing else, the result image is the inverse of the input image. What is this called? Is there any suggestions?

I wouldn't use the GuassianBlurImageFunction example as a test for
this. You should just write a short program that reads an image and
then writes it back out. Give this a try and let us know if the
problem still happens. And what do you mean by "inverse direction"? Is
the image flipped in X? Y? Both?
