添加絕對定位的文本

Question

我試圖生成一個字母，留下一個空白點，然後在其頂部粘貼地址，具體取決於信封窗口的位置。

於是我開始這樣做：

Document doc = new Document(PageSize.LETTER, 72, 72, 72, 72); 
var w = PdfWriter.GetInstance(doc, output); 
Font font = FontFactory.GetFont("arial", 10); 
doc.Open(); 
doc.Add(new Paragraph("date", font) { SpacingAfter = 5 }); 
doc.Add(new Paragraph("\n\n\n\n\n\n", font));//empty spot 
doc.Add(new Paragraph("long\n paragraph\ns panning\ multiple\n lines\n", font) { SpacingAfter = 5 }); 
doc.Add(new Paragraph("long\n paragraph\ns panning\ multiple\n lines\n", font) { SpacingAfter = 5 }); 
doc.Add(new Paragraph("long\n paragraph\ns panning\ multiple\n lines\n", font) { SpacingAfter = 5 }); 
doc.Add(new Paragraph("long\n paragraph\ns panning\ multiple\n lines\n", font) { SpacingAfter = 5 }); 
doc.Add(new Paragraph("long\n paragraph\ns panning\ multiple\n lines\n", font) { SpacingAfter = 5 }); 

float llx = 63f, lly = 450f, urx = 387f, ury = 531f; 
?? Somehow add "name\n address line 1\n address line2\n city state zip" 

doc.Close(); 

我希望能夠在這些座標添加一些文字，但我無法弄清楚如何人......知道一個辦法做到這一點？

Answer 1

找到答案「Here」。 （從Yannick Smits下面是引用答案）

===============

試試這個：SetSimpleColumn的

ColumnText ct = new ColumnText(cb); 
Phrase myText = new Phrase("TEST paragraph\nNewline"); 
ct.SetSimpleColumn(myText, 34, 750, 580, 317, 15, Element.ALIGN_LEFT); 
ct.Go(); 

參數爲：

1. 短語
2. 左下-X
3. 左下-Y
4. 右上-X（LLX +寬度）
5. 右上-γ（LLY +高度）
6. 領先（的空白空間的量的​​打印行之間）
7. 對準。

Answer 2

您還可以使用帶文本矩陣的ContentByte在任何地方繪製文本。

PdfContentByte cb = writer.DirectContent; 
cb.BeginText(); 
BaseFont f_cn = BaseFont.CreateFont("c:\\windows\\fonts\\calibri.ttf", BaseFont.CP1252, BaseFont.NOT_EMBEDDED); 
cb.SetFontAndSize(f_cn, 6); 
cb.SetTextMatrix(475, 15); //(xPos, yPos) 
cb.ShowText("Some text here and the Date: " + DateTime.Now.ToShortDateString()); 
cb.EndText(); 

好處是，如果您不必繪製文本的全部大小，文本將進入。使用簡單列，您正在文檔上繪製一個矩形，並將文本放置在其中。使用ContentByte，您避開矩形，並自行定位文本。

非常感謝您的數據，我喜歡它，但我的英語非常差，抱歉。

這是我iTextSharp etiquetas代碼：

    iTextSharp.text.Font fontH1 = new iTextSharp.text.Font(FUENTE_BASE, 14, iTextSharp.text.Font.ITALIC);
