eSign document with Text signature Leave feedback

A Text electronic signature is an arbitrary text that is added to a document in a native way depending on the type of the document. GroupDocs.Signature provides the text signature feature and allows customizing a wide range of text settings - from font name, size and color to alignment, borders, shadow effects etc. This is how a text signature may look like:  

Let’s try to add a text signature to a PDF programmatically.

To manipulate text signatures programmatically, GroupDocs.Signature provides the TextSignOptions class, and the whole workflow is as easy as follows:

• Create a new instance of the Signature class and pass the source document path as a constructor parameter.
• Instantiate the TextSignOptions object according to your requirements and specify the signature options.
• Call the Sign method of the Signature class instance and pass the TextSignOptions to it.

This example shows how to add a text signature to a document.

  // The path to the documents directory.
  const filePath = Constants.SAMPLE_PDF;
  const fileName = path.basename(filePath);

  const outputFilePath = path.join(Constants.OutputPath, 'SignWithText', fileName);
  const signature = new signatureLib.Signature(filePath);

  // Create text sign options
  const options = new signatureLib.TextSignOptions('John Smith');
  // Set signature position
  options.setLeft(100);
  options.setTop(100);

  // Set signature rectangle
  options.setWidth(100);
  options.setHeight(30);

  // Set text color and font
  //options.setForeColor(new Color(255, 0, 0)); // Red color
  const signatureFont = new signatureLib.SignatureFont();
  signatureFont.setSize(12);
  signatureFont.setFamilyName('Comic Sans MS');
  options.setFont(signatureFont);

  // Sign document to file
  signature.sign(outputFilePath, options);
  console.log(`\nSource document signed successfully.\nFile saved at ${outputFilePath}`);

This guide explains how to add text-based signatures to documents with GroupDocs.Signature . It covers configuring text properties such as font, color, size, and position, and applying the text signature to a document. The signed document is then saved with the added text signature.
