jar包:itext-asian-5.2.0.jar itextpdf-5.5.5.jar itext-1.4.6.jar
Java用iText5操作PDF itext-asian-5.2.0.jar itextpdf-5.5.5.jar itext-1.4.6.jar
说明
新建document对象
- Document document =new Document(); // 默认页面大小是A4
- Document document =new Document(PageSize.A4); // 指定页面大小为A4
- Document document =new Document(PageSize.A4,50,50,30,20); // 指定页面大小为A4,且自定义页边距
PdfWriter 对象进行磁盘写入操作
PdfWriter.getInstance(document, new FileOutputStream(filePath));
打开文档
document.open();
向文档中添加内容
document.add();
关闭文档
document.close();
段落Paragraph
Paragraph pt=new Paragraph(name,headfont);//设置字体样式
pt.setAlignment(1);//设置文字居中 0靠左 1,居中 2,靠右
pt.setIndentationLeft(12);// 左缩进
pt.setIndentationRight(12);// 右缩进
pt.setFirstLineIndent(24);// 首行缩进
paragraph.setLeading(20f); //行间距
paragraph.setSpacingBefore(5f); //设置段落上空白
paragraph.setSpacingAfter(10f); //设置段落下空白
表格table
Table table =new Table(4);//括号参数表示列
int width[] = {10,40,40};//设置每列宽度比例
table.setWidths(width);
table.setWidth(60);//占页面宽度比例
table.setAlignment(Element.ALIGN_LEFT);//居左
table.setAutoFillEmptyCells(true);//自动填满
table.setBorderWidth((float)0.1);//表格边框线条宽度
table.setPadding(1);//边距:单元格的边线与单元格内容的边距
table.setSpacing(0);//间距:单元格与单元格之间的距离
table.addCell(new Paragraph("name"),"单元格"));//添加单元格内容
table.endHeaders();//每页都会显示表头

文件如下:
加入公章(图片)
Image image1 = Image.getInstance("d:\\gongzhang.jpg");
//设置图片位置的x轴和y轴
image1.setAbsolutePosition(100, 500);//注意是从文档的坐下角往右、往上计算的
//设置图片的宽度和高度
image1.scaleAbsolute(100, 100);
//将图片1添加到pdf文件中
document.add(image1);
加入作者信息
//Anchor对象: internal and external links
Paragraph country = new Paragraph();
Anchor dest = new Anchor("china", new Font(Font.FontFamily.HELVETICA, 14, Font.BOLD, BaseColor.BLUE));
dest.setName("CN");
dest.setReference("http://www.china.com");//external
country.add(dest);
country.add(String.format(": %d sites", 10000));
document.add(country);
加入跳转到指定位置(点击跳转)
document.newPage();
Anchor toUS = new Anchor("Go to first page.", new Font(Font.FontFamily.HELVETICA, 14, Font.BOLD, BaseColor.BLUE));
toUS.setReference("#CN");//internal
document.add(toUS);
