如何创建一个iTextSharp.text.Image对象startng到System.Drawing.Bitmap对象？

Question

I am pretty new in iTextSharp (the C# version of iText ):

I have something like this:

System.Drawing.Bitmap bitmap = (System.Drawing.Bitmap)ChartHelper.GetPdfChart((int)currentVuln.UrgencyRating * 10);

iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(bitmap);

vulnerabilityDetailsTable.AddCell(new PdfPCell(img) { Border = PdfPCell.RIGHT_BORDER, BorderColor = new BaseColor(79, 129, 189), BorderWidth = 1, Padding = 5, MinimumHeight = 30, PaddingTop = 10 });  

As you can see I have classic System.Drawing.Bitmap immage named bitmap and I want put it inside a cell of a PDF document table.

The problem is that this line is signed as error:

iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(bitmap);

The error is:

Error 75 The best overloaded method match for 'iTextSharp.text.Image.GetInstance(iTextSharp.text.Image)' has some invalid arguments c:\\Develop\\EarlyWarning\\public\\Implementazione\\Ver2\\PdfReport\\PdfVulnerability.cs 120 27 PdfReport

So I think that I need to obtain an iTextSharp.text.Image object from a classic System.Drawing.Bitmap object.

What can I do to do it? I am going crazy trying to do it.

Tnx

There are no overloads that take just a System.Drawing.Image . You need to used one of these:

GetInstance(System.Drawing.Image image, BaseColor color)
GetInstance(System.Drawing.Image image, BaseColor color, bool forceBW)
GetInstance(System.Drawing.Image image, System.Drawing.Imaging.ImageFormat format)

The first one is probably the best choice and I'm 99% sure you can pass null for the color parameter.
