With GroupDocs.Signature for Node.js via Java, you can greatly improve the management of text-based signatures in key document formats. The tool allows you to configure the style, placement, and content of signatures with ease, enabling businesses to tailor their document processes.
Insert various types of signatures—such as text, images, barcodes, QR codes, or stamps—on any page of supported documents. Embed metadata to carry hidden information or apply digital certificates for advanced security measures.
Verify the authenticity of signatures embedded within your documents. Perform efficient searches to locate all signature instances, ensuring thorough document tracking and management.
Modify or delete previously added signatures as needed. You can adjust the appearance, position, or content of any signature to meet evolving requirements, ensuring flexibility in document handling.
For certain file types, tailor signature placement with built-in document features, such as adding watermarks to Word files or customized stamps to PDFs, enhancing the uniqueness of your documents.
const signatureLib = require('@groupdocs/groupdocs.signature')
// Choose the document to be signed
const signature = new signatureLib.Signature('input.pdf');
// Define text options with the specified content
const options = new signatureLib.TextSignOptions('Rescheduled to 03/04/2025');
// Set the size and position of the signature on the page
options.setLeft(100);
options.setTop(180);
options.setWidth(230);
options.setHeight(30);
// Apply padding for the signature from the page edges
const padding = new signatureLib.Padding();
padding.setBottom(20);
padding.setRight(20);
options.setMargin(padding);
// Customize the text color and font style
options.setForeColor(signatureLib.Color.RED);
const signatureFont = new signatureLib.SignatureFont();
signatureFont.setSize(12);
signatureFont.setFamilyName('Comic Sans MS');
options.setFont(signatureFont);
// Add a border to the text signature if desired
const border = new signatureLib.Border();
border.setColor(signatureLib.Color.RED);
border.setDashStyle(signatureLib.DashStyle.Dash);
border.setTransparency(0.5);
border.setVisible(true);
border.setWeight(2);
options.setBorder(border);
// Configure the background of the signature
const background = new signatureLib.Background();
background.setColor(signatureLib.Color.YELLOW);
background.setTransparency(0.8);
options.setBackground(background);
// Optionally, save the text as an image for compatibility
