GroupDocs.Signature provides a powerful tool for creating and embedding stamps, which can significantly enhance Node.js via Java applications. Use this feature to craft and apply custom stamps to your document pages.
const signatureLib = require('@groupdocs/groupdocs.signature')
// Associate the document path with the Signature instance
const signature = new signatureLib.Signature('input.pdf');
// Create StampSignOptions with the necessary signature content
const options = new signatureLib.StampSignOptions();
options.Height = 180;
options.Width = 180;
// Incorporate one or more stamp lines
const outerLine = new signatureLib.StampLine();
outerLine.setText("* The Best Company *");
outerLine.setTextRepeatType(signatureLib.StampTextRepeatType.FullTextRepeat);
outerLine.getFont().setSize(12);
outerLine.setHeight(22);
outerLine.setTextBottomIntent(6);
outerLine.setTextColor(signatureLib.Color.WHITE);
outerLine.setBackgroundColor(signatureLib.Color.BLUE);
options.getOuterLines().add(outerLine);
// Save the document with the applied stamp
const result = signature.sign('output.pdf', options);
With GroupDocs.Signature for Node.js via Java, you can add, edit, validate, or remove stamps and other signature types within all popular document formats. The API simplifies the process of managing signatures for enhanced document integrity and customization.
Apply signatures such as text, images, barcodes, QR codes, and stamps to any part of your document. This tool also allows the inclusion of hidden metadata and digital certificates to further protect your content from unauthorized modifications.
After a document has been signed, use our verification system to ensure the integrity of the signatures. Additionally, our platform enables you to search for and retrieve detailed information on all signatures applied to a document.
Adjust and update previously applied signatures with ease. Whether it’s changing the content, color, size, or position of the signature, GroupDocs.Signature for Node.js via Java offers full customization options.
Easily remove any unnecessary signatures from your documents. Our API supports the deletion of a wide range of signature types, including stamps and digital certificates, giving you complete flexibility to manage your documents.
const signatureLib = require('@groupdocs/groupdocs.signature')
// Provide the document for stamping
const signature = new signatureLib.Signature('input.pdf');
// Set up stamp options with the desired configurations
const options = new signatureLib.StampSignOptions();
// Specify the dimensions and position of the stamp on the page
options.setHeight(200);
options.setWidth(200);
options.setVerticalAlignment(signatureLib.VerticalAlignment.Bottom);
options.setHorizontalAlignment(signatureLib.HorizontalAlignment.Right);
options.setAllPages(true);
// Include outer circular lines with custom text
const outerLine1 = new signatureLib.StampLine();
outerLine1.setText('* The best choice *');
outerLine1.setTextRepeatType(signatureLib.StampTextRepeatType.FullTextRepeat);
const signatureFont1 = new signatureLib.SignatureFont();
signatureFont1.setSize(12);
signatureFont1.setFamilyName('Arial');
outerLine1.setFont(signatureFont1);
outerLine1.setHeight(30);
outerLine1.setTextBottomIntent(6);
outerLine1.setTextColor(signatureLib.Color.WHITE);
outerLine1.setBackgroundColor(signatureLib.Color.BLUE);
options.getOuterLines().add(outerLine1);
// Add inner square lines as needed
const innerLine1 = new signatureLib.StampLine();
innerLine1.setText('Company #1');
innerLine1.setTextColor(signatureLib.Color.RED);
const signFont1 = new signatureLib.SignatureFont();
signFont1.setSize(20);
signFont1.setBold(true);
innerLine1.setFont(signFont1);
innerLine1.setHeight(40);
options.getInnerLines().add(innerLine1);
// Save the stamped document
const result = signature.sign('output.pdf', options);
