We published a new version of the ASP.NET MVC DocumentViewer with two new features:

  • Signature smoothing
    Signatures are simplified with an efficient line smoothing algorithm. Lines are captured as vectors, stored in arrays and finally de-noised and simplified in a post-process.
  • Customized signature boxes
    It is possible to define the content and style of the signature boxes in the template itself. Each signature box can have it's own individual style.

You can update the NuGet package with the current version to test these new features:

Signature Smoothing

In an earlier version, we introduced the smoothing algorithm for annotations, but now the same line smoothing feature is available for drawn signatures using the signature soft pad:

Customized Signature Boxes

The signature box and the rendered information can now be completely customized. The following screenshot shows a customized signature box in the online document editor:

In case, CustomSignatureData is found in the settings, the custom content is used in the template. Otherwise, the default signature box is rendered like in previous versions of the DocumentViewer.

Signature box

The above custom signature box renders the electronic signature, the given document ID, the IP address of the user, the signer's name and a time stamp. Additionally, a barcode is added that could be used to track the document. The QR Code could contain a link that opens a website to verify the document and validity.

Thanks to the flexibility and the way how the process of signing documents can be customized, any workflow can be implemented. Feel free to contact us to learn more about how Text Control can help you adding digital and electronic signatures to your business processes.
