Processing an Image

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see API Reference.

OBS can be used to process images in a stable, secure, efficient, easy-of-use, and cost-efficient manner. If the object to be downloaded is an image, you can pass the image processing parameters to operate it, including cutting and resizing it as well as putting a watermark and converting the format.

For more information, see Image Processing Feature Guide.

Sample code:

// Import the dependency library.
require 'vendor/autoload.php';
// Import the SDK code library during the installation with source code.
// require 'obs-autoloader.php';
// Declare the namespace.
use Obs\ObsClient;
// Create an ObsClient instance.
$obsClient = new ObsClient ( [ 
      //Obtain an AK/SK pair using environment variables or import the AK/SK pair in other ways. Using hard coding may result in leakage.
      //Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
      'key' => getenv('ACCESS_KEY_ID'),
      'secret' => getenv('SECRET_ACCESS_KEY'),
      'endpoint' => 'https://your-endpoint',
      'signature' => 'obs'
] );

$resp = $obsClient -> getObject([
       'Bucket' => 'bucketname',
       'Key' => 'objectname.jpg',
       // Resize and rotate the image in sequence.
       'ImageProcess' => 'image/resize,m_fixed,w_100,h_100/rotate,90',
       'SaveAsStream' => true
]);

printf("RequestId:%s\n",$resp['RequestId']);

• Use the ImageProcess parameter to specify the image processing parameters.
• Image processing parameters can be processed in cascading mode. This indicates that multiple commands can be performed on an image in sequence.
