To perform image transformation in C# (c sharp), we'll need to use GDI+ of windows.
GDI+, supersedes GDI, is an improved 2D graphics environment. Graphics Device Interface (GDI) is one of the three core components or "subsystems" of Microsoft Windows. However, for games that need fast graphics rendering and rasterization for 3D, DirectX or OpenGL is preferred.

To use GDI+, you need to use System.Drawing namespace in C#.

For a project I am working on, I need to have a basic understanding of C#. I've heard C# for very long time and been surrounded by .net developers, but my knowledge of it stays at a very rudimentary level. I only know it's very similar to Java, like single inheritance, interface, etc, and don't really understand why many programmers told me that they feel good about using C#.
Finally I decide to take a look. This is the first tutorial I found.
