Auto - Device pixel ratio is used to determine optimum size and quality when thumbnails are generated
100 px (default)
200 px
300 px
400 px
The fixed sizes would all use a quality factor of 75.
What do you think?
I think 50 IQ is probably better for > 100x100 and saves quite a bit on file size. IIRC I tested as low as 30 IQ when comparing 200x200 to 100x100/75 (so they were the same approx file size) and didn’t notice any horrible artifacting. I don’t have any 1:1 displays so can’t say that it’s always the case but bigger thumbs at lower IQ always looked better than lower res with higher IQ to me.
The dialog looks good though.
