如何自定义iTextsharp表格“cell”使用winform控件 [英] How to customize iTextsharp table "cells" using winform controls

问题描述

我有点卡住，这是我第一次使用iTextsharp，我正在尝试创建一个生成随机数的C＃应用​​程序，然后将其作为标签打印成PDF文件报告，用户将有一个面板和标签在女巫中，他可以移动面板中的任何位置，并可以更改面板大小，就像添加图像作为背景图像一样。



现在用户进入后指定大小并将其标签拖放到面板内的所需位置并选择图像作为背景图像，我的代码将根据用户输入开始制作具有列数和行数的iTextsharp表，并且每个单元格都是必须与表格中的面板一样大小，并且具有相同的背景图像，文字必须在确切的位置，但是由用户，



工作：

1-拖放工作正常。

2-我可以打印具有用户输入的确切大小的表格单元格。



不起作用的东西：

1-我可以添加图像但是当打印到PDF时我无法将其拉伸到单元格大小

2- I无法将文本对齐到正确的位置，仅限于（CENTER，TOP_LEFT，..等）

3-我无法在图像上添加文字

这是创建表格并添加图像和文字的代码

I am a bit stuck and it's my first time using iTextsharp, I am trying to create a C# application that generate random numbers then print it into PDF file as a label Report, the user is going to have a panel and a label in witch he can move any where with in the panel and can change the panel size as will as adding an image as a background image .

Now after the user enters the specified size and "drag and drop" the label it to the desired location inside the panel and choose an image as background image, My code will start making iTextsharp table with the number of columns and rows depending on the user input, and every cell is must be as the size as the panel from the Form and have the same Background image and the text must be in the exact place as but by the user,

The things that work:
1- Drag and drop is working fine.
2- I can print the table cells with the exact size as the user input.

Things that doesn't work:
1- I can add an image but i can't stretch it to the size of the cell when printing to PDF
2- I can't align the text at an exact position ,only (CENTER ,TOP_LEFT ,..etc)
3- I can't add a text on top of the image

This is a screen shot of the Form :http://imgur.com/a/LAnSX

This is the code for creating the table and adding the image and text

private iTextSharp.text.Image myImage; 
private ImagePath = "path";

private void ExportToPDF_Click(object sender, EventArgs e)
        {
            try
            {
                saveFileDialog1.Filter = "pdf File |*.pdf";
                if (saveFileDialog1.ShowDialog() == DialogResult.OK)
                {
                    FilePath = saveFileDialog1.FileName.ToString();   
                    //create the pdf file and open it 
                    FileStream fs = new FileStream(FilePath, FileMode.Create,            FileAccess.Write, FileShare.None);
                    Document document = new Document(PageSize.A4, pageLeftMargen, pageRightMargen, pageTopMargen, pageBottomMargen);
                    PdfWriter writer = PdfWriter.GetInstance(document, fs);
                    document.Open();

                    //create the table and set width and height
                    PdfPTable table = new PdfPTable(Get_Columens_Count());
                    table.LockedWidth = true;
                    table.TotalWidth = Get_Tabel_Width();

                    //set the size for evey Cell 
                    float[] a = new float[Get_Columens_Count()];
                    for (int i = 0; i < Get_Columens_Count(); i++)
                    {
                        a[i] = Convert.ToInt32(Get_CellsWidth());
                    }
                    table.SetWidths(a);

                    //Add new cell
                    PdfPCell cell = new PdfPCell();
                    cell.BorderWidth = CellBorderWidth;
                    cell.Padding = CellsPadding;
                    cell.FixedHeight = Convert.ToInt32(Get_Cells_Height());

                    if (checkBox1.Checked == true && File.Exists(ImagePath) == true)
                    {
                        //set the image
                        myImage = iTextSharp.text.Image.GetInstance(ImagePath);
                        cell.AddElement(myImage);
                        
                    }
                       //start creating the cells 
                    for (int i = 0; i < Convert.ToInt32(Get_Records_Count()); i++)
                    {
                        table.AddCell(cell);
                    }

                    document.Add(table);

                    document.Close();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);
                throw;
            }
        }
