what's the advantage of this transform over using something like torchio.transforms.Resize?

[benjijamorris]

for e.g. transfer function, we don't know the target shape when creating the transform object, we just know the ratios we want to resize by. I haven't the torchvision and torchio resizes don't seem to work for that case, but while trying to justify this I found monai's zoom function. I'll delete these 👍
