@item intensity, i
Set intensity. Smaller values are useful to find out how many values of the same
luminance are distributed across input rows/columns.
Default value is @code{10}. Allowed range is [1, 255].
Default value is @code{0.04}. Allowed range is [0, 1].
@item mirror, r
Set mirroring mode. @code{0} means unmirrored, @code{1} means mirrored.
