Upsample an image

Hi all

When I tried downsample an image using im.resize and then
upsampled it to 
get to the original size, it looked a bit blurry and lost a
lot of details. 
How am I suppose to upsample it back to its original size
without losing 
details? Will im.transform work?

Thanks a lot

that's expected: if you downsample an image, you lose
information.  once 
lost, there's no way to get it back.

(if this wasn't the case, image compression would be a lot
easier than 
it is...)
