The watermark tool in the BQM can be scaled using only one "Size" slider. Apply it to portrait and landscape photos and you end up with a very differing watermark size. This is a feature request to let the user configure which dimension the watermark size should be scaled by - width, height, or diagonal (I guess now it uses the diagonal?). Reproducible: Always
I think currently it uses the width, always, which is why it doesn't work well when you process both portrait and landscape photos. It could work better with diagonal. Or even better, in pixels instead of %.
Created attachment 103530 [details] patch to fix the watermark size I think this is highly related to this issue here http://digikam.1695700.n4.nabble.com/Inconsistent-watermark-sizes-depending-on-pictures-ratio-td4692920.html I made a patch for minor modification.My patch doesn't allow the user to choose height or width , but it simply checks the ratio between height and width . if the height is much larger , it will modify the watermark size accordingly It produced much better results . The patch is attached

Looks good.
