The following example shows how to automatically process an image when you upload it to COS.
When the image is uploaded successfully, COS will save both the input and output images. You can later obtain the processing results using a general download request.
List<PicOperationRule> rules = new LinkedList<>(); // Add a rule to convert the image to PNG format, and the resulting image will be saved in a bucket with a location identifier in the format: // examplepngobject rules.add(new PicOperationRule("examplepngobject", "imageView2/format/png")); PicOperations picOperations = new PicOperations(true, rules); PutObjectRequest putObjectRequest = new PutObjectRequest(bucket, cosPath, srcPath); putObjectRequest.setPicOperations(picOperations); // If the upload is successful, you will get 2 images: the original and the processed images COSXMLUploadTask cosxmlUploadTask = transferManager.upload(bucket, cosPath, srcPath, uploadId);
