GroupDocs.Signature enables the generation and placement of barcodes in a variety of popular formats on PDF pages. With support for over 60 types of barcodes, Node.js via Java applications can be easily enhanced with barcode signing features by integrating our library.
const signatureLib = require('@groupdocs/groupdocs.signature')
// Instantiate a Signature object with the document path
const signature = new signatureLib.Signature('input.pdf');
// Utilize BarcodeSignOptions to integrate a barcode into the document
const options = new signatureLib.BarcodeSignOptions('Business data');
// Configure the barcode type and additional parameters
options.setEncodeType(signatureLib.BarcodeTypes.Code128);
options.setLeft(100);
options.setTop(100);
// Save the signed document
signature.sign('output.pdf', options);
The GroupDocs.Signature for Node.js via Java library is designed to streamline the signing and subsequent management of popular document formats. Quickly and easily add, modify, verify, or remove a wide range of signatures.
Sign any page of your documents using a variety of signature types, including text, images, barcodes, QR codes, and stamps. Additionally, you can embed hidden metadata, such as EXIF data in images, or secure the document against unauthorized edits using digital certificates.
Our solution provides extensive tools for managing signed documents. Verify the authenticity of signatures to ensure document integrity, and utilize the search feature to list all signatures embedded within a document.
Most signatures added previously can be effortlessly modified. Update the text, reposition, or change the appearance of the signature to match your needs.
With comprehensive support for CRUD operations, our tool allows for the efficient removal of signatures from your documents, ensuring that only the most relevant signatures remain.
const signatureLib = require('@groupdocs/groupdocs.signature')
// Provide the document to be signed
const signature = new signatureLib.Signature('input.pdf');
// Utilize BarcodeSignOptions to integrate a barcode into the document
const signOptions = new signatureLib.BarcodeSignOptions('Accepted');
signOptions.setEncodeType(signatureLib.BarcodeTypes.Code39FullASCII);
// Configure the barcode type and additional parameters
signOptions.setVerticalAlignment(signatureLib.VerticalAlignment.Bottom);
signOptions.setHorizontalAlignment(signatureLib.HorizontalAlignment.Left);
// Define the barcode padding from the page edge
const padding = new signatureLib.Padding();
padding.setLeft(20);
padding.setTop(180);
signOptions.setMargin(padding);
// Choose the bar color
signOptions.setForeColor(signatureLib.Color.RED);
// Specify the font style for the message
const font = new signatureLib.SignatureFont();
font.setSize(12);
font.setFamilyName('Arial');
signOptions.setFont(font);
// Indicate the position of the message
signOptions.setCodeTextAlignment(signatureLib.CodeTextAlignment.Above);
// Sign and save the document
signature.sign('output.pdf', signOptions);
