Dear iTexter,
I've got, so i hope, a small problem regarding the drawing of
a normal .NET Graphics object onto a pdf page. The error message
i get is "System.Drawing.Graphics can not be convert to
iTextSharp.Text.Ielement"
I've got an array of points (Start and Endpoints of lines) which i
want to get draw onto a pdf page.
My idea is to create a graphics object und use the drawlines method for it.
Here is my code
// Reading an existing pdf as "drawing background"
PdfReader reader = new
PdfReader("C:\\base.pdf");
int n = reader.NumberOfPages; Graphics grf = null; pen0.Alignment = PenAlignment.Center; grf.SmoothingMode = SmoothingMode.AntiAlias; Document document = new
Document();
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("C:\\drawingresult.pdf",FileMode.Create)); document.Open(); PdfContentByte cb = writer.DirectContent; // loop for adding any page of the base pdf into the new pdf
for (int x=1;
x<=n;x++){
try{ document.NewPage(); PdfImportedPage page =
writer.GetImportedPage(reader,x);
cb.AddTemplate(page,0,0); int scalefactorx =
(int)page.Width/700;
pen0.Width=scalefactorx; grf.DrawLines(pen0,pointarray); document.Add(grf); //<- here comes the error
???????
}catch(Exception ex){ MessageBox.Show(ex.Message.ToString()); } } Is there anyone out there who can give me a hint? Is it possible to draw a
System.Drawing.Graphics Object
onto a pdf? Is there another way to draw lines onto a pdf?
Hope for help and so far
may the force be with you
Oliver
