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 JavaScript. 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 Node 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 JavaScript.
Note: there is no need to install any third party applications or libraries. Therefore, our Node software solution is very easy to use.
The given Node 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 JavaScript, and then save the output file in a convenient format.
To evaluate our Node 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 * as fs from "fs";
const wordsApi = new WordsApi("####-####-####-####-####", "##################");
const requestDocument = fs.createReadStream("Input1.docx");
const requestImageStream = fs.createReadStream("Input2.jpg");
const requestWatermarkData = new model.WatermarkDataImage({
image: model.FileReference.fromLocalFileContent(requestImageStream)
});
const insertWatermarkRequest = new model.InsertWatermarkOnlineRequest({
document: requestDocument,
watermarkData: requestWatermarkData
});
wordsApi.InsertWatermarkOnline(insertWatermarkRequest)
.then((insertWatermarkResult) => {
console.log("Result of InsertWatermarkImageOnline: ", insertWatermarkResult);
const convertRequest = new model.ConvertDocumentRequest({
document: insertWatermarkResult.Document.Values(),
format: "docx"
});
wordsApi.convertDocument(convertRequest)
.then((convertResult) => {
console.log("Result of ConvertDocument: ", convertResult);
});
});import * as fs from "fs";
const wordsApi = new WordsApi("####-####-####-####-####", "##################");
const requestDocument = fs.createReadStream("Input.docx");
const requestWatermarkData = new model.WatermarkDataText({
text: "This is the watermark text",
layout: model.WatermarkDataText.LayoutEnum.Diagonal
})
const insertWatermarkRequest = new model.InsertWatermarkOnlineRequest({
document: requestDocument,
watermarkData: requestWatermarkData
});
wordsApi.insertWatermarkOnline(insertWatermarkRequest)
.then((insertWatermarkResult) => {
console.log("Result of InsertWatermarkTextOnline: ", insertWatermarkResult);
const convertRequest = new model.ConvertDocumentRequest({
document: insertWatermarkResult.Document.Values(),
format: "docx"
});
wordsApi.convertDocument(convertRequest)
.then((convertResult) => {
console.log("Result of ConvertDocument: ", convertResult);
});
});import * as fs from "fs";
const wordsApi = new WordsApi("####-####-####-####-####", "##################");
const requestDocument = fs.createReadStream("Input.docx");
const deleteWatermarkOnline = new model.DeleteWatermarkOnlineRequest({
document: requestDocument
});
wordsApi.deleteWatermarkOnline(deleteWatermarkOnline)
.then((deleteWatermarkOnlineResult) => {
console.log("Result of DeleteWatermarkOnline: ", deleteWatermarkOnlineResult);
const requestDocument = deleteWatermarkOnlineResult.Document.Values();
const convertDocument = new model.ConvertDocumentRequest({
document: requestDocument,
format: "docx"
});
wordsApi.convertDocument(convertDocument)
.then((convertDocumentResult) => {
console.log("Result of ConvertDocument: ", convertDocumentResult);
});
