Via Kirby 2.3’s changelog:
New Asset class, which can now convert any external files/images into Kirby file objects and make them resizable with the thumb api.
I don’t believe there’s an example of this in the docs, and I can’t quite figure it out looking at Kirby’s core. I’m familiar with creating new media objects for files within
assets (described here), but generating thumbnails from those media objects wasn’t implemented as of the 2.3 beta. Now that external images can be converted into file objects it sounds like generating thumbs from
assets should be possible.
Here’s my current code. Getting the image’s ratio, height, etc. works, but attempting to get the url for a thumbnail with either method just returns the original image’s location within
assets. No thumb is generated.
<?php $image = new Media (kirby()->roots()->index() . '/assets/images/hero-default.jpg', $site->url() . "/assets/images/hero-default.jpg"); echo $image->ratio(); echo $image->resize(1500)->url(); echo thumb($image, array('width' => 1500))->url(); ?>
