Members
| Member | Description |
|---|---|
| All | Use or compute all harmonics. If this flag is used the range rectangle and the range flags will be ignored. |
| Blue | Use the blue channel. |
| Both | Construct the image from both magnitude and phase data. |
| Clip | Clip the constructed image values so they are between 0 and 255. |
| DiscreteFourierTransform | Convert the image into frequency domain and store the results in the Data property of the FourierTransformInformation object. |
| Gray | Use the master channel. If this flag is combined with InverseDiscreteFourierTransform, the reconstructed image will be gray. |
| Green | Use the green channel. |
| InsideX | Use or compute only the X harmonics inside the X range and ignore those outside the range. |
| InsideY | Use or compute only the Y harmonics inside the Y range and ignore those outside the range. |
| InverseDiscreteFourierTransform | Construct an image using the frequency components from the Data property of the FourierTransformInformation object. This option will change the values of the Data property. |
| Magnitude | Construct the image from the frequency magnitude data only. |
| None | No change. |
| OutsideX | Use or compute only the X harmonics outside the X range and ignore those inside the range. |
| OutsideY | Use or compute only the Y harmonics outside the Y range and ignore those inside the range. |
| Phase | Construct the image from frequency phase data only. |
| Range | Use or compute the harmonics specified in the range rectangle. |
| Red | Use the red channel. |
| Scale | Scale the constructed image values so they are between 0 and 255. |
Remarks
You can use a bitwise OR (|) to specify one flag from each group.
| Group | Flags |
| Flags that represent the transformation type | DiscreteFourierTransform, InverseDiscreteFourierTransform |
| Flags that represent the operation channel type | Blue, Green, Red, Gray |
| Flags that represent the frequency data type used for constructing the image: this flag is used only if InverseDiscreteFourierTransform is set and will be ignored if DiscreteFourierTransform is set | Magnitude, Phase, Both |
| Flags that represent the clipping type. This flag is used only if InverseDiscreteFourierTransform is set and will be ignored if FFT_FFT is set | Clip, Scale |
| Flags that represent which harmonics are used | All, Range |
| Flags that represent the operations on the X Harmonics range | InsideX, OutsideX |
| Flags that represent the operations on the Y Harmonics range | InsideY, OutsideY |
