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. Create a query request. 
    1
2
    		 
    // Create a request for querying a watermark template.
QueryWatermarkTemplateRequest queryWatermarkTemplateRequest = new QueryWatermarkTemplateRequest();
  2. Set query parameters.
    1. Query by template ID

2
      		 
      String[] templateIdArray = new String[]{"template_id1", "template_id2", "template_id3"};
queryWatermarkTemplateRequest.setTemplateIds(templateIdArray);
    2. Query by page number 
      1

3
      		 
      // 2. Set the page number and number of records on each page.
queryWatermarkTemplateRequest.setPage(2);
queryWatermarkTemplateRequest.setSize(10);
  3. Send a query request and return a message.

    // Send a request to MPC.
QueryWatermarkTemplateResponse queryWatermarkTemplateResponse = mpcClient.queryWatermarkTemplate(queryWatermarkTemplateRequest);

// Return a message.
System.out.println(new Gson().toJson(queryWatermarkTemplateResponse));
