positional arguments:
  input_file            The file to rainbowiefy

optional arguments:
  -h, --help            show this help message and exit
  --blend-amount BLEND_AMOUNT, -b BLEND_AMOUNT
                        How vibrant the colours are
  --hue-rate HUE_RATE, -r HUE_RATE
                        How fast the colors change
  --duration DURATION, -d DURATION
                        How long the gif is
  --optimize            Tell the gif encoder to "optimize" it. Not sure what that
                        means
  --disable-transparency
                        Make the resulting image not have any transparency (not
                        recommended)
  --transparency-sensitivity TRANSPARENCY_SENSITIVITY, -t TRANSPARENCY_SENSITIVITY
                        if alpha < sensitivity, make that pixel transparent
  --output-file OUTPUT_FILE
                        The file to save the gif to
  --pdb                 Trips a PDB tracepoint for debugging
