datagridview中存在的图像不会导出到仅文件文本内容，而是生成PDF文件

Question

我创建了简单的桌面应用程序，因为我尝试从Datagridview生成PDF文件...当我点击ExportPDf按钮时，Pdf文件生成成功，但问题在于pdf无论datagridview中的图像是什么，图像都是不生成PDF只有文本内容存在于PDF文件中。

是否有人可以告诉我如何生成PDF文件以及图像。

这是我的代码：

    private void btnexportPDF_Click(object sender, EventArgs e)
    {
        int ApplicationNameSize = 15;<br/>
        int datesize = 12;<br/>
        Document document = null;<br/>

        try
        {
            SaveFileDialog savefiledg = new SaveFileDialog();
            savefiledg.Filter = "All Files | *.* ";

            if (savefiledg.ShowDialog() == DialogResult.OK)
            {
                string path = savefiledg.FileName;

                document = new Document(PageSize.A4, 3, 3, 10, 5);

                PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(path + ".pdf", FileMode.Create));
                document.Open();

                // Creates a phrase to hold the application name at the left hand side of the header.
                Phrase phApplicationName = new Phrase("Sri Lakshmi Finance,Hosur-560068", FontFactory.GetFont("Arial", ApplicationNameSize, iTextSharp.text.Font.NORMAL));


                // Creates a phrase to show the current date at the right hand side of the header.
                Phrase phDate = new Phrase(DateTime.Now.ToLongDateString(), FontFactory.GetFont("Arial", datesize, iTextSharp.text.Font.NORMAL));


                document.Add(phApplicationName);
                document.Add(phDate);

                iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance("D:\\logo.JPG");
                document.Add(img);

                iTextSharp.text.Font font5= iTextSharp.text.FontFactory.GetFont(FontFactory.TIMES_ROMAN, 5);
                iTextSharp.text.Font font6 = iTextSharp.text.FontFactory.GetFont(FontFactory.HELVETICA_BOLD, 6);
                //float[] columnDefinitionSize = { 2.5f, 7.0f,6.6f, 8.6f, 6.6f, 5.0f, 4.5f, 7.0f, 6.3f, 7.0f, 3.5f, 6.0f, };

                PdfPTable table = null;
                table = new PdfPTable(dataGridView1.Columns.Count);
                table.WidthPercentage = 100;

                PdfPCell cell = null;
                foreach (DataGridViewColumn c in dataGridView1.Columns)
                {
                    cell = new PdfPCell(new Phrase(new Chunk(c.HeaderText,font6)));
                    cell.HorizontalAlignment = PdfPCell.ALIGN_CENTER;
                    cell.VerticalAlignment = PdfPCell.ALIGN_CENTER;
                    cell.BackgroundColor = new iTextSharp.text.BaseColor(240, 240, 240);
                    table.AddCell(cell);
                }

                if (dataGridView1.Rows.Count > 0)
                {
                    for (int i = 0; i < dataGridView1.Rows.Count; i++)
                    {
                        PdfPCell[] objcell = new PdfPCell[dataGridView1.Columns.Count];

                        for (int j = 0; j < dataGridView1.Columns.Count - 0; j++)
                        {
                            cell = new PdfPCell(new Phrase(dataGridView1.Rows[i].Cells[j].Value.ToString(), font5));
                            cell.HorizontalAlignment = PdfPCell.ALIGN_LEFT;
                            cell.VerticalAlignment = PdfPCell.ALIGN_LEFT;
                            cell.Padding = PdfPCell.ALIGN_LEFT;
                            objcell[j] = cell;
                        }

                        PdfPRow newrow = new PdfPRow(objcell);
                        table.Rows.Add(newrow);
                    }
                }

                document.Add(table);
                MessageBox.Show("PDF Generated Successfully");
                document.Close();
            }
            else
            {
                //Error 
            }
        }
        catch (FileLoadException fle)
        {
            MessageBox.Show(fle.Message);
            MessageBox.Show("Error in PDF Generation", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }
