Image cropping doesn't work with custom center

[Jozsef]

The site is displaying a list of full body portraits that I'd like to crop with a focus on the face/shoulders.
No focus has been set on the images and it's hundreds of them so I want a sensible default.

This is the code below but it still crops from the top of the image, or the actual center (50%,50%).
Is it a bug or I'm doing something wrong?

$image = $gallery_page->images->first()->size(540,404,array("cropping" => array('50%','35%'), "quality" => 80))->webp->url;

It's based on the latest API reference I've found: https://processwire.com/api/ref/pageimage/size/
It's very late but is it something I can't spot here? Should it work?

$image = $gallery_page->images->first()->size(540, 404, [
    "cropping" => ['50%', '35%'],
    "quality" => 80,
    "focus" => false
])->webp->url;

Maybe it is auto detecting a focus presset. Try disabling it.

Thanks, it is not the problem, it would be cropped from the centre then. Interestingly, if the focus point is not set the images are cropped from North, not centre.

No matter what I tried, it doesn't work with percentages in the size options. I ended up setting the focus position for the image and it achieved the results.

if (!$image->hasFocus) $image->focus(35,50);
$resized = $image->size($w,$h)->webp->url;
