I want to create a pdf of the current xamarin form. I used pdf sharp and itext7 to implement it but unable to do it.
but below code only capture the text of xamarin, not the image. i just want to save currently viewed xamarin form to pdf.
I am struggling with this for a few weeks.

What I have tried:

var pdf = PDFManager.GeneratePDFFromView(ss);
       string localFilename = Guid.NewGuid().ToString() + ".pdf";
       string path = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + localFilename;
       DependencyService.Get<IPdfSave>().Save(pdf, localFilename);
       await Launcher.OpenAsync(new OpenFileRequest
       {
           File = new ReadOnlyFile(path)
       });
