Declaration
procedure DFT(dest: TIEVisionImage; flags: TIEVisionDFTFlags; nonZeroRows: int32_t = 0); safecall;
Description
Perform a forward or inverse Discrete Fourier Transform of a 1D or 2D floating-point image.
| Parameter | Description |
| dest | Container for the resulting image |
| flags | Transformation flags |
| nonZeroRows | When the parameter is not zero, the function assumes that only the first nonzeroRows rows of the input image (ievDFT_INVERSE is not set) or only the first nonzeroRows of the output image (ievDFT_INVERSE is set) contain non-zeros |
