Hi Simon,

It looks like there is no mention of "scaling up" or "scaling down" in the prose anymore. Instead the text now reads "The image must be scaled with the "nearest neighbor" or similar algorithm, to preserve a "pixelated" look as the image changes in size".

Do you feel your issue has been resolved?

Cheers,
Lea
