Add a text or image watermark to DOCX documents using JavaScript. Load the DOCX document and insert the required watermark into it. Then save the result in a convenient format such as DOCX, PDF, MD, HTML, TXT, DOC, RTF, EPUB, XPS and more, and share the watermarked document with another person. Also remove the watermark from DOCX document if the watermark was previously added to the document, and the reasons for adding are not longer relevant.
With this Node API, developers can add a watermark to DOCX online. Just create the watermark using text or an image and then insert that watermark into your DOCX document 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 from DOCX. Removing a watermark in DOCX means that you can load the desired DOCX document stamped with a text or image watermark, remove this watermark from the DOCX using JavaScript, and then save the output file in a convenient format – DOC, DOCX, PDF, JPEG, PNG, TIFF and others.
To evaluate how to add or remove a watermark in DOCX with our Node API, load the DOCX and the watermark as an image or text. Then select a convenient export file format – DOC, DOCX, PDF, HTML, RTF, 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);
});
