eSign document with Image signature Leave feedback

An image as a signature is an alternative way to put any presenting data in a visual form. This electronic signature type allows the creation of custom images with a company logo, sender’s initials, names and so forth.

GroupDocs.Signature provides the ImageSignOptions class to specify different settings for image signature such as image content by file or stream, location, colors and advanced effects.

Here are the steps to create an image signature on a document page:

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

This example shows how to sign a PDF document with the image signature.

using (Signature signature = new Signature("sample.pdf"))
{
    ImageSignOptions options = new ImageSignOptions("signature.jpg")
    {
        // set signature position
        Left = 100,
        Top = 100,
        //
        AllPages = true
    };
    signature.Sign("SampleSigned.pdf", options);
}

This guide demonstrates how to use GroupDocs.Signature to add image-based signatures to documents. It covers loading a document, configuring the image signature’s properties (such as size, position, and opacity), and saving the signed document. Advanced customization options, like adjusting image appearance and aligning the signature, are also discussed. For further insights, explore related document signing resources.
