Add a text or image watermark to PDF documents using Java. Load the PDF 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 PDF document if the watermark was previously added to the document, and the reasons for adding are not longer relevant.
With this Java API, developers can add a watermark to PDF online. Just create the watermark using text or an image and then insert that watermark into your PDF document in Java.
Note: there is no need to install any third party applications or libraries. Therefore, our Java software solution is very easy to use.
The given Java SDK is also helpful to remove watermarks from PDF. Removing a watermark in PDF means that you can load the desired PDF document stamped with a text or image watermark, remove this watermark from the PDF using Java, 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 PDF with our Java API, load the PDF 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 com.aspose.words.cloud.*;
ApiClient apiClient = new ApiClient("####-####-####-####-####", "##################", null);
WordsApi wordsApi = new WordsApi(apiClient);
byte[] requestDocument = Files.readAllBytes(Paths.get("Input1.pdf").toAbsolutePath());
byte[] requestImageFile = Files.readAllBytes(Paths.get("Input2.pdf").toAbsolutePath());
InsertWatermarkImageOnlineRequest insertWatermarkImageOnline =
new InsertWatermarkImageOnlineRequest(requestDocument, requestImageFile,
null, null, null, null, null, null, null, null);
InsertWatermarkImageOnline insertedWatermarkImage =
wordsApi.insertWatermarkImageOnline(insertWatermarkImageOnline);
ConvertDocumentRequest convertDocument = new ConvertDocumentRequest(
insertedWatermarkImage.getDocument().iterator().next(), "pdf",
null, null, null, null, null, null, null);
wordsApi.convertDocument(convertDocument);import com.aspose.words.cloud.*;
ApiClient apiClient = new ApiClient("####-####-####-####-####", "##################", null);
WordsApi wordsApi = new WordsApi(apiClient);
byte[] requestDocument = Files.readAllBytes(Paths.get("Input.pdf").toAbsolutePath());
WatermarkText requestWatermarkText = new WatermarkText();
requestWatermarkText.setText("This is the watermark text.");
requestWatermarkText.setRotationAngle((double)90);
InsertWatermarkTextOnlineRequest insertWatermarkTextOnline =
new InsertWatermarkTextOnlineRequest(requestDocument, requestWatermarkText,
null, null, null, null, null, null);
InsertWatermarkTextOnline insertedWatermarkText =
wordsApi.insertWatermarkTextOnline(insertWatermarkTextOnline);
ConvertDocumentRequest convertDocument = new ConvertDocumentRequest(
insertedWatermarkText.getDocument().iterator().next(), "pdf",
null, null, null, null, null, null, null);
wordsApi.convertDocument(convertDocument);import com.aspose.words.cloud.*;
ApiClient apiClient = new ApiClient("####-####-####-####-####", "##################", null);
WordsApi wordsApi = new WordsApi(apiClient);
byte[] requestDocument = Files.readAllBytes(Paths.get("Input.pdf").toAbsolutePath());
DeleteWatermarkOnlineRequest deleteWatermarkOnline =
new DeleteWatermarkOnlineRequest(requestDocument, null, null, null, null, null, null);
DeleteWatermarkOnline deletedWatermark = wordsApi.deleteWatermarkOnline(deleteWatermarkOnline);
ConvertDocumentRequest convertDocument = new ConvertDocumentRequest(
deletedWatermark.getDocument().iterator().next(), "pdf",
null, null, null, null, null, null, null);
wordsApi.convertDocument(convertDocument);Install 'Aspose.Words Cloud SDK for Java' using Maven build automation tool.
