Auto rotate and remove EXIF

The CMS Questions

Hi,

is there a Kirby way to auto-rotate an uploaded image (see also) and remove selected exif-information?

Update: I found the required command to strip selected exif-data from a folder.

exiftool -geotag= foo.jpg
or
exiftool -geotag= -r FOLDERNAME

How would I execute this command on all images as soon as I change status to visible?

You can use the panel.page.sort hook: https://getkirby.com/docs/developer-guide/advanced/hooks

When is this hook called? I am not sorting anything?

The sort hook is called when a page is sorted and when a page is made visible (i.e. make visible = sort)

Great, this is what I came up with:

kirby()->hook('panel.page.sort', function($page) {
    //base_dir = '/var/www/ge/content/';
    $files = glob('/var/www/ge/content/' . $page->diruri() . '/*.{jpg,jpeg,JPG,JPEG}', GLOB_BRACE);
    foreach($files as $file) {
        exec ('/usr/bin/exiftool -overwrite_original -P -geotag= ' . $file);
    }
    
});

Is there a better way to put the base_dir in?

You can get the root of the content folder like this:

<?php echo kirby()->urls()->content() ?>

But you might just as well use $page->files() and with a filter.
