FFT code symbian c++

I am developing an image processing application and I need to use a function that makes th FFT transform of the image.
It has to be 2-dimensional but if only a 1-dimensional function exists, it will be easy to adapt. Do somebody knows if that function (or object) exists? I have also some standart C and C++ code but I am not sure about how to use it (if it´s possible, because it has some memory allocations). I´m totally newbie so, if somebody can help me, I´d be really happy  Thank you in advance. |

Just memory allocations are easy. any use of new is ok, if it uses malloc/free you can change those for User::Alloc and User::Free.
64 bit calculations can be a bit tricky if you want to port it to old versions of symbian. In newer once, the support is better.

I think that the best code that I have is a FFT radix4 in C code especifically designed for ARM processors, but I´m not sure about how to use it.
Anyway, thanks for your advice. I will read a lot and then try to port this code.
I supose that there isn´t a known function to do this FFT with well tested code. So I have to do ir on my own.
