public function ImageImport::transform in Migrate Files (extended) 8

Same name and namespace in other branches

1. 2.0.x src/Plugin/migrate/process/ImageImport.php \Drupal\migrate_file\Plugin\migrate\process\ImageImport::transform()

Performs the associated process.

Parameters

mixed $value: The value to be transformed.

\Drupal\migrate\MigrateExecutableInterface $migrate_executable: The migration in which this process is being executed.

Return value

string|array The newly transformed value.
