[UWP] Saving ink annotations in a pdf file

Question

Hello,
I would like to create an application (uwp) for annotating PDF. I Use InkCanvas to write with the pen, I would like to save the strokes in the pdf file. The Knowledge base gives suggestions for saving strokes in an .isf file, thus separating the pdf with strokes. My goal is to save the pdf including strokes, so in a second moment you can edit the pdf and previous strokes. Is it necessary to use third party SDKs? thank you

Hello,
Welcome to Microsoft Q&A,

Saving ink annotations in a pdf file

For this scenario, we suggest you use PrintHelper to print current InkCanvas that with ink strokes to PDF(set printer as Microsoft Print to PDF).
