Another occasion when I'd usually prefer NOT to do it is for certain graphics: in particular screen shots in pages used for training or troubleshooting. Scaling up to (say) 160% can make the text in the screenshot ugly at best and sometimes difficult to read. Above 300% this isn't too big a problem. Does "very different" have a lower limit? Or is there a way to specify "only rescale pixel values to integer multiples" ? Les Brown
