Example code for Bilinear Interpolation

I'm playing with ima开发者_如何学Goges and I was wondering if anyone has a link to an open source image processing library that utilizes bilinear and bicubic interpolation for scaling and rotating images. I'm trying to learn the math behind it, so even a pretty good walk through of how these kinds of interpolations can be coded up would be excellent.

Thanks for any help

A great library is the AForge image processing library.

GDI+, aka System.Drawing.Imaging, does all of this. You do not need a 3rd party DLL. See the Graphics class.
