Add a text or image watermark to DOC documents using Dart. Load the DOC 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 DOC document if the watermark was previously added to the document, and the reasons for adding are not longer relevant.
With this Dart/Flutter API, developers can add a watermark to DOC online. Just create the watermark using text or an image and then insert that watermark into your DOC document in Dart.
Note: there is no need to install any third party applications or libraries. Therefore, our Dart/Flutter software solution is very easy to use.
The given Dart/Flutter SDK is also helpful to remove watermarks from DOC. Removing a watermark in DOC means that you can load the desired DOC document stamped with a text or image watermark, remove this watermark from the DOC using Dart, 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 DOC with our Dart/Flutter API, load the DOC 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 'package:aspose_words_cloud/aspose_words_cloud.dart';
final config = Configuration("####-####-####-####-####", "##################");
final wordsApi = WordsApi(config);
final requestDocument = (await File('Input1.doc').readAsBytes()).buffer.asByteData();
final requestImageFile = (await File('Input2.doc').readAsBytes()).buffer.asByteData();
final insertWatermarkImageOnline = InsertWatermarkImageOnlineRequest(
requestDocument, requestImageFile);
final insertedWatermarkImage = await wordsApi.insertWatermarkImageOnline(
insertWatermarkImageOnline);
final convertDocument = ConvertDocumentRequest(
insertedWatermarkImage.document.values.first, 'doc');
await wordsApi.convertDocument(convertDocument);import 'package:aspose_words_cloud/aspose_words_cloud.dart';
final config = Configuration("####-####-####-####-####", "##################");
final wordsApi = WordsApi(config);
final requestDocument = (await File('Input.doc').readAsBytes()).buffer.asByteData();
final requestWatermarkText = WatermarkText();
requestWatermarkText.text = 'This is the watermark text.';
requestWatermarkText.rotationAngle = 90;
final insertWatermarkTextOnline = InsertWatermarkTextOnlineRequest(
requestDocument, requestWatermarkText);
final insertedWatermarkText = await wordsApi.insertWatermarkTextOnline(
insertWatermarkTextOnline);
final convertDocument = ConvertDocumentRequest(
insertedWatermarkText.document.values.first, 'doc');
await wordsApi.convertDocument(convertDocument);import 'package:aspose_words_cloud/aspose_words_cloud.dart';
final config = Configuration("####-####-####-####-####", "##################");
final wordsApi = WordsApi(config);
final requestDocument = (await File('Input.doc').readAsBytes()).buffer.asByteData();
final deleteWatermarkOnline = DeleteWatermarkOnlineRequest(requestDocument);
final deletedWatermark = await wordsApi.deleteWatermarkOnline(deleteWatermarkOnline);
final convertDocument = ConvertDocumentRequest(deletedWatermark.document.values.first, 'doc');
await wordsApi.convertDocument(convertDocument);Clone Aspose.Words Cloud SDK for Dart source code from GitHub and use it in your project. Add this dependency to your pubspec.yaml: dependencies: aspose_words_cloud: 22.4.0
