DiscreteFourierTransformCommandFlags Enumeration
See Also  
Leadtools.ImageProcessing.Core Namespace : DiscreteFourierTransformCommandFlags Enumeration



Flags that indicate the transformation type, operation channel, frequency data type used to reconstruct the image, the clipping type, the used or computed frequencies range, the operation on the specified X harmonics range , and the operation on the specified Y harmonics range.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Members

MemberDescription
None No change.
DiscreteFourierTransform Convert the image into frequency domain and store the results in the Data property of the FourierTransformInformation object.
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.
Blue Use the blue channel.
Green Use the green channel.
Red Use the red channel.
Gray Use the master channel. If this flag is combined with InverseDiscreteFourierTransform, the reconstructed image will be gray.
Magnitude Construct the image from the frequency magnitude data only.
Phase Construct the image from frequency phase data only.
Both Construct the image from both magnitude and phase data.
Clip Clip the constructed image values so they are between 0 and 255.
Scale Scale the constructed image values so they are between 0 and 255.
All Use or compute all harmonics. If this flag is used the range rectangle and the range flags will be ignored.
Range Use or compute the harmonics specified in the range rectangle.
InsideX Use or compute only the X harmonics inside the X range and ignore those outside the range.
OutsideX Use or compute only the X harmonics outside the X range and ignore those inside the range.
InsideY Use or compute only the Y harmonics inside the Y range and ignore those outside the range.
OutsideY Use or compute only the Y harmonics outside the Y range and ignore those inside the range.

Remarks

You can use a bitwise OR (|) to specify one flag from each group.
