Thumbnail for Email templates

[X-Admin]

Hi,

I've noticed that Email thumbnails generated are from centre-centre of the email, so the centre of the email body is visible in the thumbnail. This doesn't look nice. Just wondering if it's possible to generate thumbnails for top-centre of the email template, so the header etc will be visible and would look better?



Cheers!

Unfortunately, there's no easy way to change the way we do resizing, sorry.

Thanks. Just trying to understand if it's something that can be included in future update?

Yes, it will.

@X-Admin - from next version, you can use a code like below in apps/init-custom.php:

hooks()->addFilter('image_helper_resize_email_template_screenshot', function (bool $resized, ImageResizeHookParams $params): bool {
    if ($resized) {
        return true;
    }
    
    $thumb = new PHPThumbGD($params->getSource());
    $thumb->crop(0, $params->getWidth(), $params->getWidth(), $params->getHeight());

    $thumb->save($params->getDestination());
    
    return true;
});

You can use any image resize library you wish, in my example I used ( because it comes with MailWizz 2.x while MailWizz 3.x will use https://image.intervention.io/v3
Maybe not the best way, but still better than nothing.
