Add EXIF Orientation upload process

Created on 10 June 2021, about 3 years ago

Updated 24 May 2023, over 1 year ago

Problem/Motivation

Having an Orientation rotate with image been uploaded from iPhones, iPads, and some other cameras
Which they look right on the original machine.
But when moved to other devices and systems. they will look with the original orientation without the the extra file attribute.

Steps to reproduce

Given that Varbase profile was installed on a remote server
And number of images/pictures had been taken with an orientation
And files been passed to an editor to upload them to the website
When uploading asset files
Then the uploaded image file and all exit image style will have a wrong rotation

Proposed resolution

Add EXIF Orientation → module to rotate the images that have an Orientation key set.

→

Rotates an image to its EXIF Orientation.

iPhone 4 and up save all images in landscape, relying on EXIF data to
set the orientation properly. This does not always translate well in the
browser or other devices.

function _exif_orientation_rotate($file) {
  if (function_exists('exif_read_data') && $file->getMimeType() == 'image/jpeg') {
    $file_exif = @exif_read_data(\Drupal::service('file_system')->realpath($file->getFileUri()));

    // Ensure that the Orientation key|value exists, otherwise leave.
    if (!is_array($file_exif) || !isset($file_exif['Orientation'])) {
      return;
    }

    // Orientation numbers and corresponding degrees.
    // @note: Odd numbers are flipped images, would need different process.
    switch ($file_exif['Orientation']) {
      case 3:
        $degrees = 180;
        break;

      case 6:
        $degrees = 90;
        break;

      case 8:
        $degrees = 270;
        break;

      default:
        $degrees = 0;
    }

    if ($degrees > 0) {
      $image = \Drupal::service('image.factory')->get($file->getFileUri());
      if ($image->rotate($degrees)) {
        $image->save();
      }
    }
  }
