Could your problem possibly have been that you weren't reducing the preview images sizes enough to view the whole image?

Well, here is one: it is better to be smart. Then I would have found the cause quickly(er).

Very many thanks for your great help!

It could be, I am not sure. But I guess, at least not solely. If I had (and I guess, I did) rezised the preview I had not been able noticing it. I would not have known what size of the preview would have been the correct one, not know the ratio the preview has compared to the "Before" view.

The preview scaling is always the same for Before and After images unless you change the setting, so the important thing is to always ensure that you are viewing the whole image when that is important.

Two things you can take away from all this is that to get the result need you only need to use the Resize action, not Canvas resize followed by Resize, and that when possible using percentage size changes with the ratio fixed is easier than calculating new pixel vales that accurately maintain the width-height ratio (or 'aspect ratio') of the image.

OK, I will consider that, thank you!

Yes, not Canvas for it, that just does not do what I wanted. And yes, percentage is very good.

Thank you very much!
