    Batch conversion: Resize - What method is used?

    So with ctrl+R I can resize an image and choose the method (Lanczos, B-Spline, ...).
    With the batch conversion I can no longer choose.

    So what method does it use?

    As far as I can tell, it uses whichever resample method you last used in IrfanView.

    A Lanczos3 resample (slowest) results in more unique colours than the hermite method (fastest). With a small batch job the speed difference was not measurable.
