Programmatically resize images uploaded

Question

When uploading images to D8 programmatically the setting for Maximum image resolution will be ignored and images will not be scaled down. Some of the images i have to upload are even larger then 10MB.

I am currently using this code.

$file_type = explode('.', $image)[1];
$data = file_get_contents($image);
$path = 'public://images/';

if (file_prepare_directory($path, FILE_CREATE_DIRECTORY)) {

  $file = file_save_data($data, $path . md5($image) . '.' . $file_type, FILE_EXISTS_REPLACE);

  $node = Node::create(array(
    'type' => 'image',
    'title' => $image,
    'field_image' => array(
      'target_id' => $file->id(),
    ),
  ));
  $node->save();

}

I've tried to work with ImageStyle::load('max_2600x2600'), but that will only create a style in styles directory.

It would be possible to use a custom shell command but i would love to use the Drupal 8 way. How to make sure original images will get resized?

Answer 1

You can Use Image style before save the node.

$original_image = 'public://images/image.jpg';

// Load the image style configuration entity.
use Drupal\image\Entity\ImageStyle;
$style = ImageStyle::load('max_2600x2600');

$uri = $style->buildUri($original_image);
$url = $style->buildUrl($original_image);

I ran into the same thing. This code ended up working for me

      use Drupal\file\Entity\File;
      use Drupal\image\Entity\ImageStyle;
      use Drupal\node\Entity\Node;

      $fileName = 'example.jpg';
      $destination =  "public://images/" . $fileName;
      $temporaryFile = 'temporary://' . $fileName;    
      file_save_data($photoData, $temporaryFile, FILE_EXISTS_REPLACE);

      $style = ImageStyle::load('thumbnail');
      $style->createDerivative($temporaryFile, $destination);

      $file = File::create([
        'uid' => 1,
        'filename' => $fileName,
        'uri' => $destination,
        'status' => 1,
      ]);
      $file->save();

      if ($file) {
          $node->get('field_photos')->appendItem([
              'target_id' => $file->id(),
              'alt' => 'Alt text goes here',
          ]);
      }

      ...

      $node->save();
