Flags # get and set (DiscreteFourierTransformCommand)
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. You can use a bitwise OR ( | ) to specify one flag from each group.
