    it starts to read a directory from the specified image file.
    For a video (a file except images), the video is read.

  Options
    -f <output_format = imgout_format or vidout_format>
        Determine the output file path format.
        This is a syntax sugar for -i and -v.
        Format Expression)
            %d - dirname of the original
            %i - filename of the original without extension
            %e - filename extension of the original
            %x - upper-left x coord
            %y - upper-left y coord
            %w - width
            %h - height
            %r - rotation degree
            %. - shear deformation in x coord
            %, - shear deformation in y coord
            %f - frame number (for video)
        Example) ./$i_%04x_%04y_%04w_%04h.%e
            Store into software directory and use image type of the original.
    -i <imgout_format = %d/imageclipper/%i.%e_%04r_%04x_%04y_%04w_%04h.png>
        Determine the output file path format for image inputs.
    -v <vidout_format = %d/imageclipper/%i.%e_%04f_%04r_%04x_%04y_%04w_%04h.png>
        Determine the output file path format for a video input.
