Itext的簡單應用和學習

1.Itext使用需要使用itext.jar包。

2.Itext使用中文，主要有兩種方式，下載itextasian.jar包，或者使用本地計算機字體。

   本地計算機字體：

<span style="font-size:12px;">  BaseFont bfHei = BaseFont.createFont("c:/Windows/fonts/SIMHEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
  Font font = new Font(bfHei, 32);
  String text = "這是黑體字測試！";
  document.add(new Paragraph(text, font));</span>

   使用iTextAsian.jar中的字體：

<span style="font-size:12px;">  BaseFont.createFont("STSong-Light", "UniGB-UCS2-H",BaseFont.NOT_EMBEDDED);</span>

3.Itext簡單實例使用。

  Document document = new Document(PageSize.A3);
  document.addAuthor("Ryan");
  document.addCreationDate();
  try {
	PdfWriter.getInstance(document, new FileOutputStream("test.pdf"));
        document.open();
	//Chunk chunk = new Chunk("Holle  樂", new Font(BaseFont.createFont("STSong-Light", "UniGB-UCS2-H",BaseFont.NOT_EMBEDDED), 32));
	document.add(new Paragraph("Holle world!"));
<span style="white-space:pre">	</span>Table table = new Table(3);
	table.setBorderWidth(1);
	table.setBorderColor(new Color(0, 0, 255));
	table.setPadding(5);
	Cell cell = new Cell("header");
	cell.setHeader(true);
	cell.setColspan(3);
	table.addCell(cell);
	cell = new Cell("example cell with colspan 1 and rowspan 2");
	cell.setRowspan(2);
	cell.setBorderColor(new Color(255, 0, 0));
	table.addCell(cell);
	table.addCell("1.1");
	table.addCell("2.1");
	table.addCell("1.2");
	table.addCell("2.2");
	table.addCell("cell test1");
	cell = new Cell("big cell");
	cell.setRowspan(2);
	cell.setColspan(2);
	cell.setBackgroundColor(new Color(0xC0, 0xC0, 0xC0));
	table.addCell(cell);
	table.addCell("cell test2");
	document.add(table);
	//document.add(chunk);
	BaseFont bfHei = BaseFont.createFont("c:/Windows/fonts/SIMHEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
	Font font = new Font(bfHei, 32);
	String text = "這是黑體字測試！";
	document.add(new Paragraph(text, font));
	document.close();
     } catch (FileNotFoundException e) {
	e.printStackTrace();
     } catch (DocumentException e) {
	e.printStackTrace();
     } catch (IOException e) {
	e.printStackTrace();
     }
