I have started to use your image service with focalpoint.
https://images.weserv.nl/docs/crop.html#focal-point

We have a focus point selector for images in the administration, but after comparing the focus point selector preview to the images scaling results, I figured out that your service does not take the percentage set, as a focus point to make the most optimale image from but as a percentage of the possible cut frames of the image matching the aspect ratio.
To me that is a stange way to handle this - why would it not be handled as a focus point which to me at least is the most logical way to implement it, though I understand that this maybe was a faster implementation..
