1. Introduction to flexpaper

Flexpaper is an open-source and lightweight Document Browsing component designed to work with libraries such as ipv2swf (including swftools), so that on the web page, it is possible to display and interact PDF files in Adobe Flex and other flash-based applications. That is, it is possible to browse the PDF file without installing the PDF Reader software. The flexpaper project also provides a flex library and an independent flash version.

2. Use flexpaper 2.1 to download flexpaper

The Project address of flexpaper on Google Code is http://code.google.com/p/flexpaper /. Currently, flexpaper's latest flashpoint is flexpaper_1.5.20.flash.zip.

After downloading and unzipping, you can see the 6-1 directory:
