Hi,
In addition to the excellent resource that Frank has pointed you to, this C++ class works OK but is a bit slow, it is probably good enough for what you need though.

The shareware routines by Marshallsoft are brilliant and fast, I have used them commercially but they are probably a bit to expensive for a home project.
