Overview

COS has integrated Cloud Infinite (CI), a one-stop professional multimedia solution that offers the image processing features outlined below. For more information, please see Image Processing Overview.

SDK API References

For the parameters and method descriptions of all the APIs in the SDK, see Api Documentation.

Processing Images Being Uploaded

The following example shows how to automatically process an image when you upload it to COS.

Upon successful upload, COS will save both the original and processed images. You can obtain the processing result using a common download request.

Sample code

PutObjectRequest request = new PutObjectRequest(bucket, key, srcPath);

JObject o = new JObject();
// Do not return the original image
o["is_pic_info"] = 0;
JArray rules = new JArray();
JObject rule = new JObject();
rule["bucket"] = bucket;
rule["fileid"] = "desample_photo.jpg";
// Processing parameters
rule["rule"] = "imageMogr2/thumbnail/400x400";
rules.Add(rule);
o["rules"] = rules;

string ruleString = o.ToString(Formatting.None);
request.SetRequestHeader("Pic-Operations", ruleString);
// Perform the request
PutObjectResult result = cosXml.PutObject(request);

Processing In-Cloud Images

The following example shows how to process an in-cloud image and store the processing result in COS.

Sample code

JObject o = new JObject();
// Do not return the original image
o["is_pic_info"] = 0;
JArray rules = new JArray();
JObject rule = new JObject();
rule["bucket"] = bucket;
rule["fileid"] = "desample_photo.jpg";
// Processing parameters
rule["rule"] = "imageMogr2/thumbnail/400x400";
rules.Add(rule);
o["rules"] = rules;
string ruleString = o.ToString(Formatting.None);

ImageProcessRequest request = new ImageProcessRequest(bucket, key, ruleString);
ImageProcessResult result = cosXml.ImageProcess(request);
