I'd like to use the Image API directly to perform few simple operations with images (I'm aware of image styles and for various reasons I would prefer to not use image styles for the application I'm working on). The trouble I'm having is what I need to pass to the Image class as the first parameter. The constructor of the Image class expects an ImageToolkitInterface $toolkit as the first parameter. I'm not sure what to plug in for it.

Hunting around the forums, I see people have used \Drupal::service('image.toolkit') to pass in as the first parameter however this isn't working for me.

Here is a snippet of one of the operations I'm attempting to perform. Feel free to pan my whole approach.

use Drupal\Core\Controller\ControllerBase;    
use Drupal\Core\Image\Image;

class myImageController extends ControllerBase { 

  public function imageHeight() {

    $image_path = 'public://path/to/image.jpg';

    $image = new Image(\Drupal::service('image.toolkit'), $image_path);

    $image_height = $image->getHeight();

    ksm([$image_height]);

    return [

      '#markup' => $this->t('Did this work?'),
    ];     
  }  
}

Does anyone know what I should use to pass in as the first parameter? I'm only using the default GD2 Image toolkit. Also, I'm on Drupal 8.6. Thanks!

  • $image = \Drupal::service('image.factory')->get($image_path);? – cchen Apr 7 at 5:11
  • I like cchen's thinking. But, if you want to keep going with your current course, I'm not seeing an image.toolkit service, but I'm seeing an image.toolkit.manager service (api.drupal.org/api/drupal/core%21core.services.yml/service/…) - maybe that's what you want, or can use – Jaypan Apr 7 at 6:49
  • Thanks cchen, your suggestion did the trick. Also, I tried the image.toolkit.manager but unfortunately that didn't work, thanks though for the suggestion. – mrlexington Apr 8 at 1:06
