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 the API Reference

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

For more information, see the Image Processing Feature Guide.

Sample code:

String endPoint = "https://your-endpoint";
String ak = "*** Provide your Access Key ***";
String sk = "*** Provide your Secret Key ***";

// Create an instance of ObsClient.
final ObsClient obsClient = new ObsClient(ak, sk, endPoint);
GetObjectRequest request = new GetObjectRequest("bucketname", "objectname.jpg");
// Resize and then rotate the image.
request.setImageProcess("image/resize,m_fixed,w_100,h_100/rotate,90");
ObsObject obsObject = obsClient.getObject(request);

obsObject.getObjectContent().close();
  • Use GetObjectRequest.setImageProcess 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.
