| Member name | Value | Description | |
|---|---|---|---|
| Forward | 1 | Apply a factor 1/N in forward transformation, but not in inverse transformation. | |
| Inverse | 2 | Apply a factor 1/N in the inverse transformation but not in forward transformation. | |
| Sqrt | 4 | Apply a factor 1/sqrt(N) in inverse and forward transformation alike. | |
| None | 8 | No or unknown normalization. |
Remarks
Effectively this is the factor before the transformation integral.
Typically the same factor should be applied in forward and inverse transform, otherwise the absolute pixel values of a transformation round trip will differ from the original pixel values.
