// 不返回原图
o["is_pic_info"] = 0;
JArray rules = new JArray();
JObject rule = new JObject();
rule["bucket"] = bucket;
rule["fileid"] = key;
//处理参数，规则参见：https://cloud.tencent.com/document/product/436/46782
rule["rule"] = "watermark/3/type/<type>/image/<imageUrl>/text/<text>/level/<level>";
rules.Add(rule);
o["rules"] = rules;
string ruleString = o.ToString(Formatting.None);
request.SetRequestHeader("Pic-Operations", ruleString);
//执行请求
PutObjectResult result = cosXml.PutObject(request);说明：更多完整示例，请前往 GitHub 查看。
示例代码二：下载时添加盲水印
