Code case sharing for generating PDF file streams using C #

This article mainly for you to introduce the C # generated PDF file stream of relevant information, with a certain reference value, interested in small partners can refer to

The example of this article for everyone to share the C # generated PDF file stream specific code for your reference, the specific content as follows

1. Set the font

static Basefont fontbase = Basefont.createfont ("C:\\windows\\fonts\\stsong. TTF ", Basefont.identity_h, basefont.embedded);    static ITextSharp.text.Font Bodyfont = new ITextSharp.text.Font (fontbase, n);    static ITextSharp.text.Font Titlefont = new ITextSharp.text.Font (fontbase);    static ITextSharp.text.Font Paragraphfont = new ITextSharp.text.Font (fontbase, n);    static ITextSharp.text.Font Linkfont = new ITextSharp.text.Font (fontbase, Font.underline, Basecolor.blue);

2. Generate a PDF file stream to return a byte array

Public byte[] Doccreate (System.Drawing.Image Image, list<treenodes> List) {MemoryStream file = new Memoryst      Ream (); String fileName = String.      Empty;      Rectangle page = pagesize.a4; Float y = page.      Height;      Document document = new Document (page, 15, 15, 30, 30); float docwidth = page.      WIDTH-15 * 2; float docheight = page. Height-document. Bottommargin-document.      TopMargin;      PDFWriter writer = pdfwriter.getinstance (document, file); Writer.      Closestream = false; Writer.      Open (); Pdfcontentbyte cb = writer.      Directcontent; Document.      Open ();      Title Paragraph title = new Paragraph (New Chunk ("title", Titlefont)); Title.      Alignment = Element.align_center; Document.      ADD (title);      Picture iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance (image, Imageformat.png); float Widthszie = (page. WIDTH-30)/img.      Width; if (Widthszie < 1) {img.      Scalepercent (Widthszie * 100); } document.Add (IMG);      Document provenance Paragraph P2 = new Paragraph (New Chunk ("provenance", Paragraphfont)); P2.      Indentationleft = Indentationleft; Document.      ADD (p2); InitData (list);//Initialize the business data createsteps (list, document, list. FirstOrDefault (IT and it).      PID = = 0);//Add Business Data////add stamp//itextsharp.text.image whyz = iTextSharp.text.Image.GetInstance (Whyzpath); Whyz.      Scalepercent (50); Whyz.      paddingtop = 100; Whyz.      Alignment = Element.align_right; Document.      ADD (Whyz); Add date Paragraph createtime = new Paragraph (New Chunk (DateTime.Now.ToLongDateString ().      ToString (), Bodyfont)); Createtime.      Alignment = Element.align_right; Createtime.      Spacingbefore =-80; Createtime.      Paddingtop = 200; Document.      ADD (Createtime); Document.      Close (); File.      Position = 0; MemoryStream newfile = Setwatermark (file, "watermark content", docwidth, docheight);//Add watermark, see another blog newfile. Position = 0;//Reset stream pointer position byte[] bytes = new Byte[newfile.      Length]; NewfiLe. Read (bytes, 0, bytes.      Length);    return bytes; }
