I need to implement Wacom tablet handwriting in my Java software and I'm using the STU SDK for Linux.
In the samples that are present in the SDK it is shown how to acquire the PenData and transform them into an image but for legal purposes I am forced to also attach the biometric data (pressure, timing) together with the image of the signature in the PDF document.
Is there a correct way or format to attach this biometric data in a PDF document?
For PDF document management in my software I use iTextPDF and Apache PDFBox.
Thank you
