UpdateWatermarkTemplateRequest req = new UpdateWatermarkTemplateRequest()
    .withBody(new WatermarkTemplate()
           // Set the template name.
            .withTemplateName("watermark_name")
           // Set the template type.
            .withType("Image")
           // Set the image watermark processing mode.
            .withImageProcess("Grayed")
           // Set the watermark width.
            .withWidth("1920")
           // Set the watermark height.
            .withHeight("1080")
           // Set the horizontal offset of the watermark relative to the video vertex.
            .withDx("10")
            // Set the vertical offset of the watermark relative to the video vertex.
            .withDy("10")
            // Set the watermark position.
            //.withReferpos("BottomLeft")
            // Set the start time of the watermark, which is used together with timeline_duration.
            .withTimelineStart("0")
            // Set the watermark duration. The default value is ToEND, indicating that the watermark persists until the video ends.
            .withTimelineDuration("ToEND"));
  2. Send the request for updating a watermark template and return a message.
