In Symfony, where to resize an image uploaded while sfValidatorFile that automatically save?

Question

In symfony 1.4, what is the best way to resize an image uploaded with a form when using sfWidgetFormInputFileEditable and sfValidatorFile and knowing that they already saved image without being asked ?

Where to put the code? I am a bit lost ...

Or should I use sfValidatorFile otherwise?

// In my form configure method:
$this->validatorSchema['image'] = new sfValidatorFile(array(
  'path'       => sfConfig::get('sf_upload_dir').'/images/',
  'mime_types' => 'web_images',
));

Thanks

A good place to do this would be overriding processValues in the form.

class FooForm extends BaseFooForm {

  public function processValues($values)
    if ($values['image'] instanceof sfValidatedFile) { // file was uploaded
      $temp = $values['image']->getTempName();
      // do image manipulation here using GD or other
      $values['image'] = $pathToSavedResizedFile;
    }
    return parent::processValues($values);
  }

}

I illustrated the same technique in an older blogpost:
