Load password-protected document Leave feedback
Some document formats also support content encryption. To load these type of documents you will have to provide the password. GroupDocs.Watermark API allows you to load content of these documents to manage watermark.
The following example demonstrates how to load an encrypted document of any supported format using the password. If the password is incorrect, InvalidPasswordException is thrown.
advanced_usage.loading_documents.LoadPasswordProtectedDocument
LoadOptions loadOptions = new LoadOptions();
loadOptions.setPassword("P@$$w0rd");
// Specify an absolute or relative path to your document. Ex: @"C:\\Docs\\protected-document.docx"
String filePath = "protected-document.docx";
Watermarker watermarker = new Watermarker(filePath, loadOptions);
// use watermarker methods to manage watermarks in the document
TextWatermark watermark = new TextWatermark("Test watermark", new Font("Arial", 12));
watermarker.add(watermark);
watermarker.save("protected-document.docx");
watermarker.close();
