Wacom’s Signature SDK library for JavaScript provides software components to capture handwritten signatures from a Web Browser.

Project mention: HexaPDF - Digital signature via sign pad | /r/ruby | 2023-11-16

To provide some context, I generate the signature image on the frontend using a sign pad (Wacom STU430) through the JavaScript library signature-sdk-js, also from Wacom. This library takes the PDF document from my Ruby backend as input and produces two output files: the PNG image of the signature and a specific ISO file. This ISO file, from what I understand, utilizing the PDF hash, ensures the secure linkage between the signature and the PDF.
