I might be doing something wrong but.. This is after the recent removal of the duplicate imresize proposed fix at bottom.

THIS WORKS
imresize(x, 2., mode='F') array([[-0.654, -0.654, -0.227, 0.201, 0.141, 0.081], [-0.654, -0.654, -0.227, 0.201, 0.141, 0.081], [ 0.242, 0.242, -0.254, -0.751, -0.806, -0.86 ], [ 1.139, 1.139, -0.282, -1.703, -1.752, -1.801], [ 0.216, 0.216, -0.818, -1.851, -1.591, -1.332], [-0.708, -0.708, -1.354, -1.999, -1.431, -0.862]], dtype=float32)
AND THIS
imresize(x, (100,100), mode='F') array([[-0.654, -0.654, -0.654, ..., 0.081, 0.081, 0.081], [-0.654, -0.654, -0.654, ..., 0.081, 0.081, 0.081], [-0.654, -0.654, -0.654, ..., 0.081, 0.081, 0.081], ..., [-0.708, -0.708, -0.708, ..., -0.862, -0.862, -0.862], [-0.708, -0.708, -0.708, ..., -0.862, -0.862, -0.862], [-0.708, -0.708, -0.708, ..., -0.862, -0.862, -0.862]], dtype=float32)
I think the problem is in line 307 size = size / 100.0 I think size needs to be a tuple looking at line 309 which is what is used for size=float size = (array(im.size)*size).astype(int)
I think the fix is percent = size / 100.0 size = (array(im.size)*percent).astype(int)
Applying that change seems to fix it. The following two operation should get the same results and do.
