Support for Manual Crop module

I guess support voor crop modules like manual crop is essential voor this module.
Setting the jpeg quality to 25 does not work if cropped images are not retinifyed.

Has anyone got this working with Manual Crop in the past two years? If not, what are the issues that need to be solved to make the two modules compatible?

I would check out the Picture module if you're looking to support high resolutions and use Manual Crop. It uses the picture element in HTML, which is the new standard for supporting high resolution images (among other things).

Here's how I got it for manual scale and crop:

function retina_images_image_effect_info_alter(&$effects) {
  if (module_exists('manualcrop')) {
    // Manual scale and crop effect
    $effects['manualcrop_crop_and_scale']['form callback'] = 'retina_images_manualcrop_crop_and_scale_form';
    $effects['manualcrop_crop_and_scale']['effect callback'] = 'retina_images_manualcrop_crop_and_scale_effect';
    $effects['manualcrop_crop_and_scale']['summary theme'] = 'retina_images_manualcrop_crop_and_scale_summary';
    $effects['manualcrop_crop_and_scale']['dimensions callback'] = 'image_resize_dimensions';
  }
}

function retina_images_theme() {
  return array(
    'retina_images_manualcrop_crop_and_scale_summary' => array('variables' => array('data' => NULL), ),
  );
}

function retina_images_manualcrop_crop_and_scale_form($data) {
  $form = manualcrop_crop_and_scale_form($data);
  retina_images_form_helper($form, $data);
  return $form;
}

function retina_images_manualcrop_crop_and_scale_effect(&$image, $data) {
  retina_images_multiply_data_dimensions($data);
  return manualcrop_crop_and_scale_effect($image, $data);
}

function theme_retina_images_manualcrop_crop_and_scale_summary($variables) {
  $data = $variables["data"];
  return theme('manualcrop_crop_and_scale_summary', $variables) . ' ' . ($data['retinafy'] ? '(' . t('retinafied') . ')' : '');
}

I did not provide a patch as this would need to be done for every manual crop effect, not scale and crop only.

manual-crop is now called manualcrop in D7 and crop + image_widget_crop in D8

D7 reached its EOL back in January 2025, and there is no active release for D7 for this module anymore.
Development or support is not planned for D7. All D7-related issues are marked as outdated in a bunch.
