Features Overview PDF4NET is a .NET library for generating and importing pdf documents on the fly from any .NET application. The library does not rely on any Adobe products for creating and importing pdf files. It hides the complex structure of pdf files behind a simple object model that allows creation of complex pdf files or import of existing pdf files with a few lines of code. The PDF4NET library follows the GDI+ model, thus reducing the learning time and increasing productivity. It uses a grid based layout approach allowing precise positioning of content on document's pages. The final pdf file is compressed, making the library apropriate for web applications. The library can be used both from WinForms and WebForms (ASP.NET) applications without any restrictions. Also, the same package includes a Compact .NET Framework edition of the library. The library is written entirely in C#, being 100% managed. The PDF4NET library is licensed per developer and can be distributed ROYALTY FREE, reducing your project costs.
