    ppmshadow path/to/input_file.ppm > path/to/output_file.ppm
  • [b]lur the image by the specified number of pixels:
    ppmshadow -b n path/to/input_file.ppm > path/to/output_file.ppm
  • Specify the displacement of the simulated light source to the left and the top of the image:
    ppmshadow -x left_offset -y top_offset path/to/input_file.ppm > path/to/output_file.ppm
