First, the process

Second, simple example:

1) Create a table instance

Program:

        /// <summary>        ///Create a PDF file/// </summary>        Private voidcreatpdftable () {//Print a PDF table            stringPdfname =string.            Empty; SaveFileDialog Dlg=NewSaveFileDialog (); Dlg. FileName="PDF Table"; Dlg. DefaultExt=". pdf"; Dlg. Filter="Text documents (. pdf) |*.pdf"; if(DLG. ShowDialog () = =DialogResult.OK) {pdfname=dlg.                FileName; FileStream FS=NewFileStream (Pdfname, FileMode.Create);//Create a file streamDocument document =NewDocument (PageSize.A7.Rotate ());//Create File PageSize.A7.Rotate () indicates A7 paper transverse outputPDFWriter PDFWriter = pdfwriter.getinstance (document, FS);//instantiation ofDocument. Open ();//Open FileDocument. ADD (NewParagraph ("1")); Document.               ADD (PDFTable1 ()); //Add a tabledocument.       SetPageSize (PAGESIZE.A6); //A6 paper longitudinal outputDocument. NewPage ();//a new pageDocument. ADD (NewParagraph ("2")); Document.                ADD (PDFTable2 ()); Document. ADD (NewParagraph ("3")); Document.                ADD (PDFTable3 ()); Document.                        Close (); //Close FileFS.            Close (); }        }        /// <summary>        ///CREATE table 1/// </summary>        /// <returns></returns>        Privatepdfptable PDFTable1 () {varTable1 =NewPdfptable (4);//Create a Table instance 4 column            int[] A = {1,2,3,4};//set the column width scaletable1.            Setwidths (a);  for(inti =0; I < -; i++) {table1. Addcell ((i+1). ToString ());//Add Cells            }             returntable1; }        /// <summary>        ///CREATE TABLE 2/// </summary>        /// <returns></returns>        Privatepdfptable PDFTable2 () {//Font Definition            varBfchinese = Basefont.createfont (@"C:\windows\fonts\simkai.ttf", Basefont.identity_h, basefont.not_embedded);//Simkai.ttf            varChfont_12 =NewITextSharp.text.Font (Bfchinese, A); varChfont_10 =NewITextSharp.text.Font (Bfchinese,Ten); varChfont_8 =NewITextSharp.text.Font (Bfchinese,8); varchfont_12_red =NewITextSharp.text.Font (Bfchinese, A, ITextSharp.text.Font.ITALIC, basecolor.red); varTable2 =NewPdfptable (4);//Create a Table instancePdfpcell Cell; Cell=NewPdfpcell (NewPhrase (Convert.ToString (1) , chfont_10)); Cell.

Setwidths (a);  for(inti =0; I < -; i++)            {                if(i = =Ten) {Pdfpcell cell=NewPdfpcell (PDFTable2 ());//Add Table 2 to a cellCell. Padding =0;//table and cell spacing are 0;Table3.                    Addcell (cell); Continue; } table3. Addcell ("3");//Add Cells            }            returnTable3; }

2) Create a picture

Program:

 Private voidBtnpdfimage_click (Objectsender, EventArgs e) {            stringPdfname =string.            Empty; SaveFileDialog Dlg=NewSaveFileDialog (); Dlg. FileName="PDF Image"; Dlg. DefaultExt=". pdf"; Dlg. Filter="Text documents (. pdf) |*.pdf"; if(DLG. ShowDialog () = =DialogResult.OK) {pdfname=dlg.                FileName; FileStream FS=NewFileStream (Pdfname, FileMode.Create);//Create a file streamDocument document =NewDocument (PageSize.A5.Rotate ());//Create File PageSize.A5.Rotate () indicates A5 paper transverse outputPDFWriter PDFWriter = pdfwriter.getinstance (document, FS);//instantiation ofDocument. Open ();//Open FileDocument. ADD (AddImage (document));//Add a pictureDocument. ADD (AddImage2 (document));//Add a pictureDocument. Close ();//Close FileFS.            Close (); }        }         /// <summary>        ///PDF Add Picture/// </summary>        /// <returns></returns>        PrivateiTextSharp.text.Image AddImage (document document) {ITextSharp.text.Image Hglogo= ITextSharp.text.Image.GetInstance ("yijing.jpg");  Hglogo.scalepercent (4f); //Picture ProportionsHglogo.setabsoluteposition (40f, document. PAGESIZE.HEIGHT-100F);//iamge Location            returnHglogo; }        /// <summary>        ///PDF Add Image 2/// </summary>        /// <param name= "document" ></param>        /// <returns></returns>        PrivateiTextSharp.text.Image AddImage2 (document document) {ITextSharp.text.Image Hglogo= ITextSharp.text.Image.GetInstance ("yijing.jpg");  Hglogo.scalepercent (12f); //Picture ProportionsHglogo.setabsoluteposition (200f, document.
