Resample: Axis direction

[schm0]

Hello!
The DirectMLX.h header file has the following definition:

    inline Expression Resample(
        Expression input,
        TensorDimensions outputSizes,
        DML_INTERPOLATION_MODE mode,
#if DML_TARGET_VERSION >= 0x5100
        DML_AXIS_DIRECTION roundingDirection = DML_AXIS_DIRECTION_INCREASING,
#endif // DML_TARGET_VERSION >= 0x5100
        Span<const float> scales = {},
        Span<const float> inputPixelOffsets = {},
        Span<const float> outputPixelOffsets = {} 
#if DML_TARGET_VERSION >= 0x6400
        , bool antialiased = false
#endif
        )

How should the axis direction calculated?
e.g. different direction for down or up sampling? Different direction for nearest neighbor vs linear?
Or does that not really matter?
Thanks!
