C# Save Bitmap as PDF With iTextSharp

Question

The following code creates a bitmap from a control on the form, and then shows a save dialog to save as a JPEG. Can anyone help with the code to save the Bitmap bm as a PDF with iTextSharp?

 Bitmap bm = null;
 bm = new Bitmap(this.RCofactorTBS.SelectedTab.Width, this.RCofactorTBS.SelectedTab.Height);
 this.RCofactorTBS.SelectedTab.DrawToBitmap(bm, this.RCofactorTBS.SelectedTab.ClientRectangle);

 SaveFileDialog dialog = new SaveFileDialog();
 dialog.Filter = "JPEG|*.jpeg";
 dialog.Title = "Save Test As Jpeg";
 dialog.ShowDialog();

 if (dialog.FileName != "" && bm != null)
 {
    bm.Save(dialog.FileName);
 }

Solution

You can try this

System.Drawing.Image image = System.Drawing.Image.FromFile("Your image file path");
Document doc = new Document(PageSize.A4);
PdfWriter.GetInstance(doc, new FileStream("image.pdf", FileMode.Create));
doc.Open();
iTextSharp.text.Image pdfImage = iTextSharp.text.Image.GetInstance(image, System.Drawing.Imaging.ImageFormat.Jpeg);
doc.Add(pdfImage);
doc.Close();

the idea is not to save the image to a file first. i want to save the "bm" object to the pdf without saving to a file first

You can directly pass the bitmap to the image.

OK i got this working. But, the image doesn't fit inside the pdf document. Any idea how i can make it fit?

Could you please edit in an explanation (in English; the Spanish comments here will be difficult for most users to make any use of) of why this code answers the question? Code-only answers are discouraged, because they don't teach the solution.
