How to get a color image after fourier transform?

[chonghoong]

Hi,

I applied fourier transform to an image but when I convert back to BitMap using ComplexImage.ToBitmap()

it returns me a greyscale image. Is there anyway to get a color image?

thanks.


This is my source codes:
************************************************************************************************************************************
AForge.Imaging.ComplexImage myComplexImage = AForge.Imaging.ComplexImage.FromBitmap("A.bmp");
myComplexImage.ForwardFourierTransform();
AForge.IntRange range = new AForge.IntRange(0,100);
myComplexImage.FrequencyFilter(range);
myComplexImage.BackwardFourierTransform();

// this is greyscale instead of color
Bitmap transformedBitmap = myComplexImage.ToBitmap();
************************************************************************************************************************************

Thanks alot for your help!
