Good day,
Is there one better example to create PDF file? I used code below and PDF file then is empty (cannot be opened).
PdfWriter pdfWriter = new PdfWriter("f:\l0\A0.pdf");
PdfDocument pdfD0 = new PdfDocument(pdfWriter);
Document D0 = new Document(pdfD0);

2020-10-24T12:28:47.337+00:00 It is Java code...
in C#, you can find samples from Google like
Create a new PdfDocument from other PdfDocument pieces that are created in memory with itext7 - c#for PageSize :
var doc = new Document(pdfDocument, new PageSize(298f, 178f)); -

Is there example/details to put text at specific position within PDF file? And example to create rectangle in that.-

2020-10-26T16:57:25.833+00:00 For example :
Paragraph paragraph = new Paragraph("This is a test\n"); paragraph.SetFixedPosition(10, 10, 100); paragraph.SetBorder(new iText.Layout.Borders.SolidBorder(1));or see the documentation for more advanced samples; the samples are in Java , but the code is nearly the same in C#
