====Amplitude Spectrum====
Get Amplitude Spectrum from "fft", and store to "img".
void lmrcFFTAmplitude(mrcImage* img, mrcImage* fft);
Get Amplitude Spectrum's Log from "fft", and store to "img".
void lmrcFFTLogAmplitude(mrcImage* img, mrcImage* fft ,double data);

====Power Spectrum====
Get Power Spectrum from "fft", and store to "img".
void lmrcFFTPower(mrcImage* img, mrcImage* fft);
Get Power Spectrum's Log from "fft", and store to "img".
void lmrcFFTLogPower(mrcImage* img, mrcImage* fft ,double data);

====Phase Spectrum====
Get Phase Spectrum from "fft", and store to "img".
void lmrcFFTPhase(mrcImage* img, mrcImage* fft);

====Real Part====
Get Real Part from "fft", and store to "img".
void lmrcFFTReal(mrcImage* img, mrcImage* fft);

====Offset====
Get Offset for 1DFT(fft->Header=mrcComplexFloatOneDimFT). (Otherwise, return 0.)
long lmrcFFTExpressionOffset(mrcImage* fft);

===Output API Information===
It outputs Mode details.
