Question

I am generating a pdf file in asp.net c# using itextsharp. i am not able to draw a horizontal line/verticle line/dotted line.

i tried to draw a line using the following code,i am getting no errors but the line is also not getting displayed in the pdf file

    PdfContentByte cb = wri.DirectContent;
    cb.SetLineWidth(2.0f);   // Make a bit thicker than 1.0 default
    cb.MoveTo(20, pdfDocument.Top - 40f);
    cb.LineTo(400, pdfDocument.Top - 40f);
    cb.Stroke();

What is the problem in the code.Is it because of the position of x y co-ordinates? I had used rough points to know approximate position in pdf,but the line never apears in the pdf file.

The output i am looking out for is as shown in image below.

You should always make sure to set the color for the operation that you’re performing, otherwise you won’t know what you’ll get (it will be from whatever previous operation was performed). Try doing cb.setStrokeColor(255, 0, 0) (pure red) until you get your line where you want it.
