Use the different classes in the System.Drawing namespace.

Alternatively, use one of the many drawing libraries around.

Note:

The documentation on MSDN gives the following warning:

Classes within the System.Drawing namespace are not supported for use within a Windows or ASP.NET service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions. For a supported alternative, see Windows Imaging Components.

However, I and others who have done so have not found problems. Even MSDN magazine suggests it...

There's a very good, detailed article at the 4guysfromrolla web site. I used this the first time I needed to do such a thing, and I still use the same pattern.

This one is fairly good as well, but nowhere near as well-explained as the first one. http://blogs.sitepoint.com/generating-asp-net-images-fly/
