The +antialias option is a draw option, whcih means it is for drawing objects and text on images. Anti-aliasing on resizing images is achieved in other ways See Filters and Resize Suport Factor http://www.cit.gu.edu.au/~anthony/graphics/imagick6/resize/#filters Also JPEG images stent to distort images so much they produce weird edge effects, which could be mis-interpreted as anti-aliasing.
