WPViewPDF是一款比较新的控件，通过它可以查看PDF数据格式的数据内容，而这些数据内容可以来自内存，文件以及其他数据流。WPViewPDF是比较成熟的控件，它为使用者提供了自带窗口形式的人机交流方式，这使得WPViewPDF可以在任何装有Windows系统的开发环境中使用。

　　WPViewPDF主要用于快速查看及打印PDF文件，PDF文件可以由wPDF，wPDF控件或者wRTF2PDF生成，甚至可以是其他电脑数据库内的PDF文件。WPViewPDF控件可以直接嵌入到您的应用程序之中。但是对于那些使用非常规字体的PDF文档，在WPViewPDF无法正确显示其内容。

　　现在，WPViewPDF还可以支持那些符合ANSI标准的文本文件，并提供关键字查找和函数语法突出的功能。

为什么我需要一个PDF浏览器控件？

• 如果您需要您的应用程序嵌入PDF浏览功能，那么从现在开始，只要您拥有WPViewPDF便可以满足您的要求，而不再需要依靠Acrobat(tm) Viewer 6或其更高版本。
• 如果您需要从内存中加载PDF文件，那么只要您拥有了WPViewPDF，便可以从任何的数据流中加载PDF文件。在加载PDF数据的过程中，通过WPViewPDF中与数据流的接口程序，您还可以使用您自己的密码模式对PDF数据进行加密和解密。
• 如果您需要打印您的应用软件所生成的PDF文件，那么只要您拥有了WPviewPDF，便可以在只使用一台打印机的情况下，同时打印多个PDF文件，而不需要再开启其他的打印程序。
• 如果您需要把PDF文件的信息作为您应用程序的背景图像，那么只要您拥有了WPviewPDF，便可以从PDF文件中，以图像文件的方式提取任一PDF页面为您所用。
• 最后但不是最终一点：设想一个基于PDF文件的工具，它功能强大，并支持多路打印和预览功能。同时您还可以通过它预览，打印（在WPViewPDF或者其他程序中），存储以及以电子邮件形式发送PDF文件。这样的工具难道您不想拥有吗？

一个控件便已足够――无需其他OCX控件

• 现在，在您的应用程序中创建PDF文档，并且可以即时地预览该PDF文档，这已经成为可能。WPviewPDF便是实现这一目的的最理想的工具。虽然WPviewPDF无法保证可以显示所有的PDF文档，但是足可以显示并打印那些由PDF工具或者其他同类工具生成的PDF文件。现在，在WPviewPDF的控件包中，并同时提供了支持Delphi/C++编译器和.NET的WPviewPDF控件。
• WPViewPDF已经实现自带窗口形式的人机交流方式，因此您无需担心购买WPViewPDF后仍要为其升级付出更多的金钱，即使您更换了原来的开发环境，您依然可以继续使用原有的WPViewPDF控件工具。

WPViewPDF is a new component which allows you to view PDF data. The data can be loaded from memory, file or stream. This component has been developed as a window class which makes it compatible to most Windows based development systems.

　　WPViewPDF is usually used to quickly display and print PDF files which were created with our wPDF, wPDFControl or wRTF2PDF or with a competitor's library. It is directly embedded in your application. WPViewPDF is not able to display PDF files correctly which make use of Type1 fonts.

　　WPViewPDF now supports ANSI text extraction and text find + highlight functionality!

Why do I need a PDF viewer component?

• If you need to embed a PDF viewer into your application, then you need WPViewPDF since this will, most likely, no longer be allowed with the Acrobat(tm) Viewer Version 6 or later.
• If you need to load PDF files from memory, then you need WPviewPDF which will allow you to load PDF files from any stream. The stream interface makes it possible for you to use your own encryption/decryption scheme for the loading process.
• If you need to print the PDF files created by your own application, then you need WPviewPDF which makes it possible to print several PDF files using just one printer job without starting any external application．
• If you need to use information from PDF files as background images in your application, then you need WPViewPDF since it has the ability to extract PDF pages as metafiles.
• Last but not least: Imagine a powerful and versatile print and preview system which is based completely on PDF files. The PDF files can be viewed, printed (with WPViewPDF or another program), stored or sent via e-mail!

One Component for all - no OCX

• Finally it is now possible to not only create PDF files from your application, but also to view them almost instantly. WPViewPDF is the ideal component for this purpose. Although WPViewPDF cannot ensure that you will be able to view all kinds of PDF files, it is powerful enough to display and print PDF files generated with our own PDF tools or similar products. At presently the wrapper for both Delphi/C++Builder and .NET are included.
• Since WPViewPDF has been implemented as a window class, there's no need to worry about the longivity of your investment - you can still use this component even if you switch development systems.
