PDFWriter可以使用一下兩種方式創(chuàng)建PDF文件：

• 可以使用jPDFWriter非常簡單的API直接創(chuàng)建PDF文件。用戶可以方便的創(chuàng)建PDFDocument對象，創(chuàng)建盡可能多的PDFPage對象以滿足需要，在頁面上畫線條，圖片以及其他Graphics2D支持的元素，然后將之保存
• jPDFWriter也擴(kuò)展了標(biāo)準(zhǔn)的PrinterJob以幫助用戶以如同使用物理打印機(jī)時(shí)創(chuàng)建的PDF文件一般的方式創(chuàng)建PDF文件。這可以幫助用于重用即在的打印編碼，且可以幫助應(yīng)用程序在運(yùn)行時(shí)決定是否需要將輸出發(fā)送至打印機(jī)或者PDF文件

主要功能

• 其效仿了java圖形和打印類，因此盡可能的減少了代碼修改和訓(xùn)練
• 用戶在部署其應(yīng)用程序的時(shí)候無需安裝或者配置附加的驅(qū)動(dòng)程序或者軟件
• 完全使用Java™編寫-允許用戶的應(yīng)用程序保持平臺(tái)獨(dú)立性
• 支持PDF文件壓縮，以減小體積
• 支持對PDF文件進(jìn)行加密和權(quán)限設(shè)置
• 支持字體嵌入
• 支持可選模式的JBIG2圖像
• 可在運(yùn)行的時(shí)候決定送至打印機(jī)還是保存至文件
• 支持所有的圖片格式，包括JBIG2 和 JPEG 2000
• 在JDK 1.3.1及其以上環(huán)境中經(jīng)過測試

PDFWriter can create PDF files in two ways:

• PDF files can be created directly using jPDFWriter's very simple API. Simply create a PDFDocument object, create as many PDFPage objects as necessary, draw strings, graphics or any other elements supported by Graphics2D to the pages and then save the document.
• jPDFWriter also extends the standard Java PrinterJob so that you can create PDF files in the same way that you would print to a physical printer. This allows for reuse of existing printing code and for an application to decide, at runtime, whether to send the output to a printer or to a PDF file.

Main Features

• Emulates the java graphics and printing classes, thus minimizing code changes and training.
• No need to install or configure additional drivers or software when deploying your application.
• Written entirely in Java™ - allows your application to remain platform independent.
• Supports PDF compression for smaller document size.
• Support for PDF encryption and permissions
• Support for embedding fonts.
• Support for JBIG2 images with optional module.
• Allows runtime decision to go to a printer or to a PDF file.
• Support for all image types, including JBIG2 and JPEG 2000.
• Tested on JDK 1.3.1 and above.
