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
- Document document = new Document();
- PdfWriter.getInstance(document, new FileOutputStream(FILE_DIR + "createSamplePDF.pdf"));
- document.open();
- document.add(new Paragraph("Hello World"));
- document.close();
2、页面大小,页面背景色,页边空白,Title,Author,Subject,Keywords
- Rectangle rect = new Rectangle(PageSize.B5.rotate());
- rect.setBackgroundColor(BaseColor.ORANGE);
-
- Document doc = new Document(rect);
-
- PdfWriter writer = PdfWriter.getInstance(doc, out);
-
- writer.setPdfVersion(PdfWriter.PDF_VERSION_1_2);
-
- doc.addTitle("[email protected]");
- doc.addAuthor("[email protected]");
- doc.addSubject("[email protected] sample");
- doc.addKeywords("[email protected]");
- doc.addCreator("[email protected]");
-
- doc.setMargins(10, 20, 30, 40);
-
- doc.open();
- doc.add(new Paragraph("Hello World"));
3、设置密码
- PdfWriter writer = PdfWriter.getInstance(doc, out);
-
- writer.setEncryption("Hello".getBytes(), "World".getBytes(),
- PdfWriter.ALLOW_SCREENREADERS,
- PdfWriter.STANDARD_ENCRYPTION_128);
-

- Image img = Image.getInstance("resource/watermark.jpg");
- img.setAbsolutePosition(200, 400);
- PdfContentByte under = stamp.getUnderContent(1);
- under.addImage(img);
-
- PdfContentByte over = stamp.getOverContent(2);
- over.beginText();
- BaseFont bf = BaseFont.createFont(BaseFont.HELVETICA, BaseFont.WINANSI,
- BaseFont.EMBEDDED);
- over.setFontAndSize(bf, 18);
