PDFWriter可以使用一下兩種方式創建PDF文件：

• 可以使用jPDFWriter非常簡單的API直接創建PDF文件。用戶可以方便的創建PDFDocument對象，創建盡可能多的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也擴展了標準的PrinterJob以幫助用戶以如同使用物理打印機時創建的PDF文件一般的方式創建PDF文件。這可以幫助用于重用即在的打印編碼，且可以幫助應用程序在運行時決定是否需要將輸出發送至打印機或者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練
• 用戶在部署其應用程序的時候無需安裝或者配置附加的驅動程序或者軟件
• 完全使用Java™編寫-允許用戶的應用程序保持平臺獨立性
• 支持PDF文件壓縮，以減小體積
• 支持對PDF文件進行加密和權限設置
• 支持字體嵌入
• 支持可選模式的JBIG2圖像
• 可在運行的時候決定送至打印機還是保存至文件
• 支持所有的圖片格式，包括JBIG2 和 JPEG 2000
• 在JDK 1.3.1及其以上環境中經過測試

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.
