Use the following example to see how it works:
using Aspose.Words.Cloud.Sdk;
var config = new Configuration
{
ClientId = "####-####-####-####-####",
ClientSecret = "##################"
};
var wordsApi = new WordsApi(config);
using var requestDocument = File.OpenRead("Input1.docx");
using var requestImageFile = File.OpenRead("Input2.docx");
var request = new InsertWatermarkImageOnlineRequest(
document: requestDocument,
imageFile: requestImageFile
);
var actual = await this.WordsApi.InsertWatermarkImageOnline(request);
var convertRequest = new ConvertDocumentRequest(actual.Document.Values.First(),
"docx");
var convert = await wordsApi.ConvertDocument(convertRequest);using Aspose.Words.Cloud.Sdk;
var config = new Configuration
{
ClientId = "####-####-####-####-####",
ClientSecret = "##################"
};
var wordsApi = new WordsApi(config);
using var requestDocument = File.OpenRead("Input.docx");
var requestWatermarkText = new WatermarkText()
{
Text = "This is the watermark text",
RotationAngle = 90f
};
var request = new InsertWatermarkTextOnlineRequest(
document: requestDocument,
watermarkText: requestWatermarkText
);
var actual = await this.WordsApi.InsertWatermarkTextOnline(request);
var convertRequest = new ConvertDocumentRequest(actual.Document.Values.First(),
"docx");
var convert = await wordsApi.ConvertDocument(convertRequest);using Aspose.Words.Cloud.Sdk;
var config = new Configuration
{
ClientId = "####-####-####-####-####",
ClientSecret = "##################"
};
var wordsApi = new WordsApi(config);
using var requestDocument = File.OpenRead("Input.docx");
var deleteWatermarkRequest = new DeleteWatermarkOnlineRequest(requestDocument);
var response = await WordsApi.DeleteWatermarkOnline(deleteWatermarkRequest);
var convertRequest = new ConvertDocumentRequest(response.Document.Values.First(),
"docx");
var convert = await wordsApi.ConvertDocument(convertRequest);Install 'Aspose.Words Cloud SDK for .NET' using NuGet package manager.
