Hello, Mark. I fixed my code a little bit. Please check this new version. I think it will be faster than before.

Now you can save a complex number image such as Fourier's coefficient image.
Pixels in a color image also can have complex numbers.
The fourth channel on a color image will be regarded as an alpha blending channel.

Now you can save image to a sub directory.
