hi Cory, I hope you are well you and your family in these days of pandemic Covid-19.
I don't know if you are still maintaining the NoPoDoFo library, I was working today with NoPoDoFo and the library doesn't sign properly the pdf documents generated from Puppeteer ( HTML -> PDF )

the image is very small its backwards rotated and it's not within coordinates that I am passing for rect.left and rect.bottom
