使用PHP将水印添加到AWS S3存储桶中的图像中吗？

Question

Is it possible apply watermark on image stored AWS S3 Bucket using PHP?

I have tried with following for retrieve if image exist or not and after watermark applied.

    $galleryImg = '_1473241284.jpg';
    // echo $galleryImg;
    test(file_exists('https://s3-ap-southeast-1.amazonaws.com/bucketname/test123/'.$galleryImg));

    //for direct apply watermark on server
    if(file_exists('https://s3-ap-southeast-1.amazonaws.com/bucketname/test123/'.$galleryImg)){
    // test("hiii");
    // echo "hii";
    $watermark->apply('https://s3-ap-southeast-1.amazonaws.com/bucketname/test123/'.$galleryImg, 'https://s3-ap-southeast-1.amazonaws.com/bucketname/test123/'.$galleryImg, $watermarkImg, 3);

    $response1 = $client->putObject(array('Bucket' => BUCKETNAME, 'Key' => 'bucketname/test123/'.$galleryImg, 'SourceFile' => 'https://s3-ap-southeast-1.amazonaws.com/bucketname/test123/'.$galleryImg, 'ACL' => 'public-read'));
    //echo "watermark applied";
    }

Rather than applying a watermark and saving the image back to Amazon S3, you could use a third-party service to apply the watermark on-the-fly :

• Watermark with imgix
• Watermark with Cloudinary
