[INFO] [Feature request] Keep height ?

[Selur]

keeping the height, it will modify the width

Yes, depending on whether 'Crop/Resize->Base->Picture Resize->Auto adjust' is set to 'height' or 'width' the height or width will be adjusted. So if you want to keep the height tell Hybrid to adjust the width to archive PAR 1:1.

Is it already possible, or is it a feature to develop ?

Everything I mentioned should work fine in Hybrid.
