When use ippiResizeSqrPixel_32f_C1R, what's the image centerdoes it take?

e.g. Foraimage 512*512. Which image center does it take?(index start from 0)

1) The exact center : x = (512-1)/2 = 255.5 , y= (512-1)/2 = 255.5

2)x=(512/2)-1=255, y=(512/2)-1 = 255

3) x=(512/2)+1=256, y=(512/2)+1=256.

In which documentIcanfind the related information? Thank you very much.
