using Spire.Cloud.Word.Sdk.Api;
using Spire.Cloud.Word.Sdk.Client;
using Spire.Cloud.Word.Sdk.Model;


namespace AddTextWatermark
{
    class Program
    {
        static string appId = "App ID";
        static string appKey = "App Key";
        static string baseUrl = "https://api.cloudxdocs.com";
        //Create a Configuration instance based on your AppID and AppKey
        static Configuration wordConfiguration = new Configuration(appId, appKey, baseUrl);
        //Create an WatermarksApi instance
        static WatermarksApi watermarksApi = new WatermarksApi(wordConfiguration);

        static void Main(string[] args)
        {
            //Specify the input Word document
            string fileName = "WatermarkExample.docx";
            //Specify the folder storing the document, and it's "null" if nothing
            string folder = "input";
            //Use the 2G storage provided by E-iceblue, and it's "null" by default
            string storage = null;
            //Specify the password used to open the document, and it's "null" if nothing
            string password = null;
            //Create a TextWatermark instance
            TextWatermark body = new TextWatermark("Confidential")
            {
                Layout = TextWatermark.LayoutEnum.Diagonal,
                Font = new Font(60, "Arial")
                {
                    Color = new Color(100, 100, 100)
                }
            };
            //Specify the file path of the output Word document
            string destFilePath = "output/setTextWatermark_output.docx";
            //Call the SetTextWatermark method to add text watermark to the document and save it to the specified path
            watermarksApi.SetTextWatermark(name, body, destFilePath, folder, storage, password);
        }
