crop and rotate - flip & align the horizon

Aligning an Image with the crop and rotate module is a great feature, which I use very often.
This time I flipped the image first. Now, the aligning process is not working in the usual manner…
I just just can’t align the horizon.
I’m using dt 3.0, are there any changes in the module?

You have to undo the flip, then align, then flip. Alignment after flip (horizontal) works the other way around. I think it’s mentioned in the manual.

Thanks, that works !
