Protect your documents from unauthorized distribution and add the watermark online. To do this, just load a PDF, Word or other document format and add a text or image watermark using Swift. Then save the watermarked PDF or Word document in a convenient format such as DOC, DOCX, PDF, HTML, RTF, XPS and others. You can also remove the watermark from documents to make them easier to process unless it violates anyone's rights.
With this Swift API, developers can add a watermark to PDF, Word, or other documents online. You can create the watermark using text or an image and then insert that watermark into your PDF or Word document by setting the overlay angle in Swift.
Note: there is no need to install any third party applications or libraries. Therefore, our Swift software solution is very easy to use.
The given Swift SDK is also helpful to remove watermarks. For example, removing a watermark in Word means that you can load the desired Word document stamped with a text or image watermark, remove this watermark from the document using Swift, and then save the output file in a convenient format.
To evaluate our Swift API, load the document to which you want to add a watermark and the watermark as an image or text. Then select a convenient export file format – DOCX, PDF, MD, HTML, TXT, DOC, RTF, EPUB, XPS and others.
Use the following example to see how it works:
import AsposeWordsCloud
let config = Configuration(
clientId: "####-####-####-####-####", clientSecret: "##################");
let api = try WordsAPI(configuration: config);
let requestDocument = InputStream(url: URL(string: "Input1.docx"))!;
let requestImageFile = InputStream(url: URL(string: "Input2.docx"))!;
let insertWatermarkImageOnline = InsertWatermarkImageOnlineRequest(
document: requestDocument, imageFile: requestImageFile);
let insertedWatermarkImage = try api.insertWatermarkImageOnline(
request: insertWatermarkImageOnline);
let convertDocument = ConvertDocumentRequest(
document: insertedWatermarkImage.document.values.first, format: "docx");
_ = try api.convertDocument(request: convertDocument);import AsposeWordsCloud
let config = Configuration(
clientId: "####-####-####-####-####", clientSecret: "##################");
let api = try WordsAPI(configuration: config);
let requestDocument = InputStream(url: URL(string: "Input.docx"))!;
let requestWatermarkText = WatermarkText()
.setRotationAngle(rotationAngle: 90)
.setText(text: "This is the watermark text.");
let insertWatermarkTextOnline = InsertWatermarkTextOnlineRequest(
document: requestDocument, watermarkText: requestWatermarkText);
let insertedWatermarkText = try api.insertWatermarkTextOnline(
request: insertWatermarkTextOnline);
let requestDocument = InputStream(url: URL(string: "document"))!;
let convertDocument = ConvertDocumentRequest(
document: insertedWatermarkText.document.values.first, format: "docx");
_ = try api.convertDocument(request: convertDocument);import AsposeWordsCloud
let config = Configuration(
clientId: "####-####-####-####-####", clientSecret: "##################");
let api = try WordsAPI(configuration: config);
let requestDocument = InputStream(url: URL(string: "Input.docx"))!;
let deleteWatermarkOnline = DeleteWatermarkOnlineRequest(document: requestDocument);
let deletedWatermark = try api.deleteWatermarkOnline(request: deleteWatermarkOnline);
let convertDocument = ConvertDocumentRequest(
document: deletedWatermark.document.values.first, format: "docx");
_ = try api.convertDocument(request: convertDocument);You can use Swift package manager and Cocoapods dependency manager to install Aspose.Words Cloud SDK for Swift. Detailed information on installing the package is given in the "Installation and Usage" section.
As an alternative, you can clone Aspose.Words Cloud SDK for Swift source code from GitHub and use it in your project.
