A couple of days ago i found a great framework called AForge.NET.
AForge.NET is a C# framework designed for developers and researchers in the fields of Computer Vision and Artificial Intelligence – image processing, neural networks, genetic algorithms, machine learning, robotics, etc.
Sometimes, you’re faced with the problem to cramp as many smaller textures as possible onto a larger texture. Typical cases are lightmaps, which are very small textures with dimensions that usually are not powers of two, or bitmap fonts where you want to try and fit the entire ascii character set onto a texture without wasting much space.
What you need then, is a rectangle packer, an algorithm that arranges as many smaller rectangles on a larger rectangle as can possibly fit.
This is a C# class which allows you to create Web and WinForm captcha control.
The class is very configurable, so finaly you could create a Captcha that suits your needs.
You can hold the Captcha secret key as a session or an encrypted cookie variable.

Once upon a time there were objects like ASPJeg which made it possible to manipulate images files – resize, convert and much more…
Lucky for us those times are gone and now we have a great framework called .NET, so why not use it ?
