如何在Magento 2中删除产品图像

I'm trying to remove product images in Magento 2, but all I can find is how to do it in Magento 1, which is very different.

Here is what I found for Magento 1:

if ($product->getId()){
    $mediaApi = Mage::getModel("catalog/product_attribute_media_api");
    $items = $mediaApi->items($product->getId());
    foreach($items as $item)
        $mediaApi->remove($product->getId(), $item['file']);
}

Anyone know how to accomplish this?

Here we learn how to remove images from product.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); // Instance of object manager
/*Remove Images From Product*/
$productId = 100; // Id of product
$product = $objectManager->create('Magento\Catalog\Model\Product')->load($productId);
$productRepository = $objectManager->create('Magento\Catalog\Api\ProductRepositoryInterface');
$existingMediaGalleryEntries = $product->getMediaGalleryEntries();
foreach ($existingMediaGalleryEntries as $key => $entry) {
    unset($existingMediaGalleryEntries[$key]);
}
$product->setMediaGalleryEntries($existingMediaGalleryEntries);
$productRepository->save($product);

/*Add Images To The Product*/
$imagePath = "sample.png"; // path of the image
$product->addImageToMediaGallery($imagePath, array('image', 'small_image', 'thumbnail'), false, false);
$product->save();
