fourierTransformInformation
FourierTransformInformation structure. The Data property of the FourierTransformInformation structre is a two-dimensional array holding the frequency components.
rectangle
Specifies the filter dimension that will be applied, it represents the frequency range to be kept or removed. The left value refers to the minimum X harmonic, the right refers to the maximum X harmonic, the top refers to the minimum Y harmonic and the bottom refers to the maximum Y harmonic. The maximum X harmonic equals Width -1 and the maximum Y harmonic equals Height -1.
flags
Flags that indicate the operation to be performed on the specified X and Y harmonics ranges. You can use a bit wise OR (|) to specify one flag from each group.
Initializes a new FrequencyFilterCommand class object with explicit parameters.
