Hi, sorry about it, I just solve it recently, by only new sig. Now I try to append sig. I used this library, pdf.js and jspdf.js.
First, i got a signed PDF from my colleague. And the PDF signed with iText on Android.
When i got it, i decode it with pdf.js, and console.log() the orginal data of signature.
But I just got some ojb except the Image data. the image data is a binarystring.
So, it used jspdf.js to create a new pdf, this is very helpful. It can convert a image to binary and make a SMask obj.
