It's a good idea to look at the PDF created with PDF File writer. This is one of the most important reasons why I occasionally come across very shocked and shared.

2. A simple use case

We can get started quickly and take a look at the basic code, according to the official examples.

2.1 Create a Base object first

Private pdffontarialnormal;private pdffontarialbold;private pdffontarialitalic;private PdfFontArialBoldItalic; Private pdffonttimesnormal;private pdffontcomic;private Pdftilingpattern watermark;private PdfDocumentDocument; Private Pdfpagepage;private pdfcontentscontents;

Then create a blank document

Step 1: Create empty documents, document parameters have types, can be selected using enumerations, and return file names document = new Pdfdocument (Papertype.letter, False, Unitofmeasure.inch, FileName);//Cryptographic Test example//document.setencryption (null, NULL, Permission.all & ~permission.print, encryptiontype.aes128);//create PDF file information Directory Pdfinfo info = pdfinfo.createpdfinfo (document); info. Title ("article Example"); Info. Author ("Uzi granot Granotech Limited"); Info. Keywords ("PDF,. NET, C #, Library, Document Creator"); Info. Subject ("PDF File Writer C # Class Library (Version 1.14.1)");

2.2 Creating resources such as fonts

Define a different font type, as shown in string FontName1 = "Arial"; String FontName2 = "Times New Roman"; Arialnormal = Pdffont.createpdffont (Document, FontName1, Fontstyle.regular, true); Arialbold = Pdffont.createpdffont (Document, FontName1, FontStyle.Bold, true); Arialitalic = Pdffont.createpdffont (Document, FontName1, Fontstyle.italic, true); Arialbolditalic = Pdffont.createpdffont (Document, FontName1, FontStyle.Bold | Fontstyle.italic, True); Timesnormal = Pdffont.createpdffont (Document, FontName2, Fontstyle.regular, true); Comic = Pdffont.createpdffont (Document, "Comic Sans MS", FontStyle.Bold, True);

2.3 Creating a text sample

Contents.drawtext (Comic, 40.0, 4.25, 9.25, Textjustify.center, 0.02, Color.FromArgb (0, 255), Color.FromArgb (255, 0, "PDF FILE WRITER"); Contents.savegraphicsstate (); Contents.setcolornonstroking (color.purple); Contents.drawtext (Comic, 30.0, 4.25, 8.75, Textjustify.center, "Example"); Contents.restoregraphicsstate ();//step 3: Add new pages page = new Pdfpage (Document);//step 4: Add content to page Contents = new Pdfcontents ( Page);

2.4 Drawing Barcodes

Contents.savegraphicsstate (); BarcodeEAN13 Barcode1 = new BarcodeEAN13 ("1234567890128"); Contents.drawbarcode (1.3, 7.05, 0.012, 0.75, Barcode1, Arialnormal, 8.0); Pdfqrcode QRCode = new Pdfqrcode (Document, "http://www.codeproject.com/Articles/570682/ Pdf-file-writer-csharp-class-library-version ", errorcorrection.m); Contents.drawqrcode (QRCode, 6.0, 6.8, 1.2);//Add Link page.addweblink (6.0, 6.8, 7.2, 8.0, "http://www.codeproject.com/ Articles/570682/pdf-file-writer-csharp-class-library-version ");//Save Contents.restoregraphicsstate ();

2.5 Drawing a chart

Contents.savegraphicsstate ();//Create Ms chart Chart Chart piechart = pdfchart.createchart (Document,  1.8, 1.5, 300.0); Pdfimagecontrol imagecontrol = new pdfimagecontrol ();imagecontrol.saveas =  Saveimageas.indexedimage; Pdfchart piepdfchart = new pdfchart (Document, piechart, imagecontrol); piechart.antialiasing = antialiasingstyles.none; //Setting the color piechart.backcolor =  Color.FromArgb (220, 220, 255); piechart.palette = chartcolorpalette.brightpastel;//Default Font font defaultfont =  Piepdfchart.createfont ("Verdana",  fontstyle.regular, 0.05, fontsizeunit.userunit); Font titlefont = piepdfchart.createfont ("Verdana", fontstyle.bold, 0.07,  Fontsizeunit.userunit);//  Set the title Title title1 = new title ("Pie chart example",  docking.top, titlefont, color.purple); PIECHART.TITLES.ADD (TiTLE1);//Legend Legend legend1 = new legend (); PIECHART.LEGENDS.ADD (LEGEND1); Legend1.backcolor = color.fromargb (230, 230, 255); legend1.docking = docking.bottom; legend1.font = defaultfont;//  chart Area chartarea chartarea1 = new chartarea (); PIECHART.CHARTAREAS.ADD (CHARTAREA1); Chartarea1.backcolor = color.fromargb (255, 200, 255); Series series1 = new series (); PIECHART.SERIES.ADD (SERIES1); series1.charttype = seriescharttype.pie; series1.font = defaultfont; series1.isvalueshownaslabel = true; series1.labelformat =  "{0} %"; SERIES1.POINTS.ADD (22.0); Series1.points[0]. legendtext =  "Apple"; SERIES1.POINTS.ADD (27.0); SERIES1.POINTS[1]. legendtext =  "Banana"; SERIES1.POINTS.ADD (33.0); SERIES1.POINTS[2]. legendtext =  "Orange"; SERIES1.POINTS.ADD (18.0); SERIES1.POINTS[3]. legendtext =  "Grape"; Contents.drawchart (PIEPDFChart, 5.6, 5.0);//  save Contents.restoregraphicsstate (); 

2.6 Generate PDF

Step 6: Create Pdfdocument.createfile ();//open PDF file Process Proc = new process (); Proc.startinfo = new ProcessStartInfo (FileName); Proc.start ();
