Querying Watermark Templates

Notes

  • You can query watermark templates by template ID or page number.
  • A maximum of 10 template IDs can be queried at a time.
  • The page number and maximum number of templates on each page must be specified for pagination query. If no parameters are specified, page is 0 and size is 10.

Core Code

  1. Set query parameters.
    1. Query watermark templates by template ID. 
      1
      		 
      ListWatermarkTemplateRequest req = new ListWatermarkTemplateRequest().withTemplateId(Collections.singletonList(215728));
    2. Query watermark templates by page number. 
      1
2
      		 
      Pagination query based on page and size
ListWatermarkTemplateRequest req = new ListWatermarkTemplateRequest().withPage(1).withSize(10);
  2. Send a query request and return a message. 
    1

    // Send a request to MPC.
ListWatermarkTemplateResponse rsp = initMpcClient().listWatermarkTemplate(req);
// Print the response message.
System.out.println("rsp=" + JsonUtils.toJSON(rsp));
