用于跨平台 PDF 开发的 .NET/Mono 库。
XFINIUM.PDF code can be compiled on all supported platforms without changes. The library features a wide range of capabilities, for both beginers and advanced PDF developers. The development style is based on fixed document model, where each page is created as needed and content is placed at fixed position using a grid based layout. This gives you access to all PDF features, whether you want to create a simple file or you want to create a transparency knockout group at COS level, and lets you build more complex models on top of the library. XFINIUM.PDF has been developed entirely in C# and it is 100% managed code. With XFINIUM.PDF you can port your PDF application logic to other platforms with zero effort which means faster time to market. Simple licensing per developer with royalty free distribution helps you keep your costs under control.
