iText是著名的开放项目，是用于生成PDF文档的一个java类库。通过iText不仅可以生成PDF或rtf的文档，而且可以将XML、Html文件转化为PDF文件。

http://itextpdf.com/

版本：itextpdf-5.2.1.jar

1、生成一个PDF

//Step1—CreateaDocument.
Documentdocument=newDocument();
//Step2—GetaPdfWriterinstance.
PdfWriter.getInstance(document,newFileOutputStream(FILE_DIR+"createSamplePDF.pdf"));
//Step3—OpentheDocument.
document.open();
//Step4—Addcontent.
document.add(newParagraph("HelloWorld"));
//Step5—ClosetheDocument.
document.close();

2、页面大小,页面背景色,页边空白,Title,Author,Subject,Keywords

//页面大小
Rectanglerect=newRectangle(PageSize.B5.rotate());
//页面背景色
rect.setBackgroundColor(BaseColor.ORANGE);

Documentdoc=newDocument(rect);

PdfWriterwriter=PdfWriter.getInstance(doc,out);

//PDF版本(默认1.4)
writer.setPdfVersion(PdfWriter.PDF_VERSION_1_2);

//文档属性
doc.addTitle("Title@sample");
doc.addAuthor("Author@rensanning");
doc.addSubject("Subject@iTextsample");
doc.addKeywords("Keywords@iText");
doc.addCreator("Creator@iText");

//页边空白
doc.setMargins(10,20,30,40);

doc.open();
doc.add(newParagraph("HelloWorld"));

3、设置密码

PdfWriterwriter=PdfWriter.getInstance(doc,out);

//设置密码为："World"
writer.setEncryption("Hello".getBytes(),"World".getBytes(),
PdfWriter.ALLOW_SCREENREADERS,
PdfWriter.STANDARD_ENCRYPTION_128);

doc.open();
doc.add(newParagraph("HelloWorld"));

4、添加Page

document.open();
document.add(newParagraph("Firstpage"));
document.add(newParagraph(Document.getVersion()));

document.newPage();
writer.setPageEmpty(false);

document.newPage();
document.add(newParagraph("Newpage"));

5、添加水印(背景图)

//图片水印
PdfReaderreader=newPdfReader(FILE_DIR+"setWatermark.pdf");
PdfStamperstamp=newPdfStamper(reader,newFileOutputStream(FILE_DIR
+"setWatermark2.pdf"));

Imageimg=Image.getInstance("resource/watermark.jpg");
img.setAbsolutePosition(200,400);
PdfContentByteunder=stamp.getUnderContent(1);
under.addImage(img);

//文字水印
PdfContentByteover=stamp.getOverContent(2);
over.beginText();
BaseFontbf=BaseFont.createFont(BaseFont.HELVETICA,BaseFont.WINANSI,
BaseFont.EMBEDDED);
over.setFontAndSize(bf,18);
over.setTextMatrix(30,30);
over.showTextAligned(Element.ALIGN_LEFT,"DUPLICATE",230,430,45);
over.endText();

//背景图
Imageimg2=Image.getInstance("resource/test.jpg");
img2.setAbsolutePosition(0,0);
PdfContentByteunder2=stamp.getUnderContent(3);
under2.addImage(img2);

stamp.close();
reader.close();

cell=newPdfPCell(newParagraph("blahblahblahblahblahblahblahblahblahblahblahblahblahblahblahblahblahblahblahblah"));
cell.setNoWrap(false);
table.addCell(cell);

//不折行
table.addCell(newPdfPCell(newParagraph("不折行",fontZH)));
cell.setNoWrap(true);
table.addCell(cell);

//设置高度
table.addCell(newPdfPCell(newParagraph("任意高度",fontZH)));
cell=newPdfPCell(newParagraph("1.blahblah\n2.blahblahblah\n3.blahblah\n4.blahblahblah\n5.blahblah\n6.blahblahblah\n7.blahblah\n8.blahblahblah"));

//蓝色背景，上边框
cell=newPdfPCell(newParagraph("蓝色背景，上边框",fontZH));
cell.setBorder(Rectangle.TOP);
cell.setUseBorderPadding(true);
cell.setBorderWidthTop(5f);
cell.setBorderColorTop(BaseColor.CYAN);
cell.setBackgroundColor(BaseColor.BLUE);
table.addCell(cell);

cell=newPdfPCell(newParagraph("背景灰色度",fontZH));
table.addCell(cell);
cell=newPdfPCell(newParagraph("0.25"));
cell.setBorder(Rectangle.NO_BORDER);
cell.setGrayFill(0.25f);
table.addCell(cell);
cell=newPdfPCell(newParagraph("0.5"));
cell.setBorder(Rectangle.NO_BORDER);
cell.setGrayFill(0.5f);
table.addCell(cell);
cell=newPdfPCell(newParagraph("0.75"));
cell.setBorder(Rectangle.NO_BORDER);
cell.setGrayFill(0.75f);
table.addCell(cell);

document.add(table);

28、插入图像

Imageimage=Image.getInstance("resource/test2.jpg");
float[]widths={1f,4f};

PdfPTabletable=newPdfPTable(widths);

//插入图片
table.addCell(newPdfPCell(newParagraph("图片测试",fontZH)));
table.addCell(image);

//调整图片大小
table.addCell("Thistwo");
table.addCell(newPdfPCell(image,true));

//不调整
table.addCell("Thisthree");
table.addCell(newPdfPCell(image,false));
document.add(table);

29、设置表头

String[]bogusData={"M0065920","SL","FR86000P","PCGOLD",
"119000","9606","2001-08-13","4350","6011648299",
"FLFLMTGP","153","119000.00"};
intNumColumns=12;
//12
PdfPTabledatatable=newPdfPTable(NumColumns);
intheaderwidths[]={9,4,8,10,8,11,9,7,9,10,4,10};//percentage
datatable.setWidths(headerwidths);
datatable.setWidthPercentage(100);
datatable.getDefaultCell().setPadding(3);
datatable.getDefaultCell().setBorderWidth(2);
datatable.getDefaultCell().setHorizontalAlignment(Element.ALIGN_CENTER);

datatable.addCell("Clock#");
datatable.addCell("TransType");
datatable.addCell("Cusip");
datatable.addCell("LongName");
datatable.addCell("Quantity");
datatable.addCell("FractionPrice");
datatable.addCell("SettleDate");
datatable.addCell("Portfolio");
datatable.addCell("ADPNumber");
datatable.addCell("AccountID");
datatable.addCell("RegRepID");
datatable.addCell("AmtToGo");

datatable.setHeaderRows(1);

//边框
datatable.getDefaultCell().setBorderWidth(1);

//背景色
for(inti=1;i<1000;i++){
for(intx=0;x<NumColumns;x++){
datatable.addCell(bogusData[x]);
}
}

document.add(datatable);

30、分割表格

//横向分割
PdfContentBytecb=writer.getDirectContent();
PdfPTabletable=newPdfPTable(10);
for(intk=1;k<=100;++k){
table.addCell("Thenumber"+k);
}
table.setTotalWidth(400);

table.writeSelectedRows(0,5,0,-1,5,700,cb);
table.writeSelectedRows(5,-1,0,-1,210,700,cb);

31、设置单元格留白

PdfPTabletable=newPdfPTable(2);
PdfPCellcell;
Paragraphp=newParagraph("Quickbrownfoxjumpsoverthelazydog.Quickbrownfoxjumpsoverthelazydog.");
table.addCell(newPdfPCell(newParagraph("默认",fontZH)));
table.addCell(p);
table.addCell(newPdfPCell(newParagraph("Padding：10",fontZH)));
cell=newPdfPCell(p);
cell.setPadding(10f);
table.addCell(cell);
table.addCell(newPdfPCell(newParagraph("Padding：0",fontZH)));
cell=newPdfPCell(p);
cell.setPadding(0f);
table.addCell(cell);
table.addCell(newPdfPCell(newParagraph("上Padding：0左Padding：20",fontZH)));
cell=newPdfPCell(p);
cell.setPaddingTop(0f);
cell.setPaddingLeft(20f);
table.addCell(cell);
document.add(table);

document.newPage();
table=newPdfPTable(2);
table.addCell(newPdfPCell(newParagraph("没有Leading",fontZH)));
table.getDefaultCell().setLeading(0f,0f);
table.addCell("blahblah\nblahblahblah\nblahblah\nblahblahblah\nblahblah\nblahblahblah\nblahblah\nblahblahblah\n");
table.getDefaultCell().setLeading(14f,0f);
table.addCell(newPdfPCell(newParagraph("固定Leading：14pt",fontZH)));
table.addCell("blahblah\nblahblahblah\nblahblah\nblahblahblah\nblahblah\nblahblahblah\nblahblah\nblahblahblah\n");
table.addCell(newPdfPCell(newParagraph("相对于字体",fontZH)));
table.getDefaultCell().setLeading(0f,1.0f);
table.addCell("blahblah\nblahblahblah\nblahblah\nblahblahblah\nblahblah\nblahblahblah\nblahblah\nblahblahblah\n");
document.add(table);

32、设置单元格边框

//没有边框
PdfPTabletable1=newPdfPTable(3);
table1.getDefaultCell().setBorder(PdfPCell.NO_BORDER);
table1.addCell(newParagraph("Cell1"));
table1.addCell(newParagraph("Cell2"));
table1.addCell(newParagraph("Cell3"));
document.add(table1);

//边框粗细颜色
document.newPage();
Rectangleb1=newRectangle(0f,0f);
b1.setBorderWidthLeft(6f);
b1.setBorderWidthBottom(5f);
b1.setBorderWidthRight(4f);
b1.setBorderWidthTop(2f);
b1.setBorderColorLeft(BaseColor.RED);
b1.setBorderColorBottom(BaseColor.ORANGE);
b1.setBorderColorRight(BaseColor.YELLOW);
b1.setBorderColorTop(BaseColor.GREEN);
PdfPTabletable2=newPdfPTable(1);
PdfPCellcell=newPdfPCell(newParagraph("Cell1"));
cell.cloneNonPositionParameters(b1);
table2.addCell(cell);
document.add(table2);
