Set image focus through API

[Gideon So]

Is it possible to set page image focus through a hook??

I tried this piece of code but it seems doesn't work.

wire()->addHookAfter('Pages::saveReady', function ($event) {
    $page = $event->arguments(0);
    if(count($page->pageBanner)){
      $page->of(false);
      $page->pageBanner->focus(10,10);
      $page->save();
      $page->of(true);
    }
});

Processwire throw this error:

Method Pageimages::focus does not exist or is not callable in this context

Any ideas is much welcome.

When output formatting is off the value of a Images field is a Pageimages object (WireArray). So you have to do:

$page->pageBanner->first()->focus(10,10);

I see. Learn a lesson. Thanks @Robin S

In case someone need the solution:

wire()->addHookBefore('Pages::saveReady', function ($event) {
    $page = $event->arguments(0);
    if(count($page->pageBanner)){
      $page->of(false);
      $page->pageBanner->first()->focus([top],[left]);
      $page->of(true);
    }
});

…doesn't work if you also set a size? like:

$thumb = $foo->images->first->focus(0,0); // works

$thumb = $foo->images->first->size(400, 400)->focus(0,0); // doesn't work

I feel like it would make more sense to call focus() first and size() afterwards, but I haven’t tested or read up on anything.

I don't know and it's very hard to find out because everything image related in the CMS is very unreliable for lack of a better word. I don't know if the images are cached somewhere, on the server, in the browser? Any changes I take don't have any effect, setting the image focus manually in the input dialogue, not even rotating or flipping changes anything. I delete all image variations, rename the images, nothing helps. All stays the same so it's hard to say if the API is correct or not.
