Drawing in MigraDoc document using XGraphics - pdfsharp

Question

I have generated some PDF report using MigraDoc. Initial code is as follows:-
MigraDoc.DocumentObjectModel.Document document = new MigraDoc.DocumentObjectModel.Document();
MigraDoc.DocumentObjectModel.Section section = document.AddSection();
...
Paragraph paragraph = section.Headers.Primary.AddParagraph();
....
table = section.AddTable();
...
paragraph = section.Footers.Primary.AddParagraph();
...
The PDF was rendered successfully. Now I want to add some graphics into the pages of this document. I have gone through several articles for that and found that everyone using PdfDocument class instead of MigraDoc.DocumentObjectModel.Document. Is it possible to apply graphics into pages of a document of type MigraDoc.DocumentObjectModel.Document using XGraphics? If it is not possible, what is the best way to mix PdfDocument with MigraDoc.DocumentObjectModel.Document to accomplish the same?

Answer 1

MigraDoc uses PDFsharp and an XGraphics object to create the PDF pages.
There are several ways to add content to pages created by MigraDoc.
This MigraDoc sample shows some options:

You can even call MigraDoc to use "your" XGraphics object for drawing:
// Alternative rendering with progress indicator.
// Set a callback for phase 1.
pdfRenderer.DocumentRenderer.PrepareDocumentProgress += PrepareDocumentProgress;
// Now start phase 1: Preparing pages (i.e. calculate the layout).
pdfRenderer.PrepareRenderPages();
// Now phase 2: create the PDF pages.
Console.WriteLine("\r\nRendering document ...");
int pages = pdfRenderer.DocumentRenderer.FormattedDocument.PageCount;
for (int i = 1; i <= pages; ++i)
{
var page = pdfRenderer.PdfDocument.AddPage();
Console.Write("\rRendering page " + i + "/" + pages);
PageInfo pageInfo = pdfRenderer.DocumentRenderer.FormattedDocument.GetPageInfo(i);
page.Width = pageInfo.Width;
page.Height = pageInfo.Height;
page.Orientation = pageInfo.Orientation;
using (XGraphics gfx = XGraphics.FromPdfPage(page))
{
gfx.MUH = pdfRenderer.Unicode ? PdfFontEncoding.Unicode : PdfFontEncoding.WinAnsi;
gfx.MFEH = pdfRenderer.FontEmbedding;
pdfRenderer.DocumentRenderer.RenderPage(gfx, i);
}
}
Console.WriteLine("\r\nSaving document ...");
