Encoding of images into audio using the SSTV standard (and its most popular encoding modes such as Martin, Robot and Scottie).

  SampleRate: 41000,
  NumChannels: 1,
})

// Or for the other modes:
// sstv.NewPasokon(sstv.Pasokon3, format)
// sstv.NewRobot(sstv.Robot36, format)
// sstv.NewScottie(sstv.Scottie1, format)
// sstv.NewWrasse(sstv.WrasseSC2180, format)
// For a full list of mode constants, refer to the package documentation

# Generate a Robot36 encoded image:
$ sstv-cli -r36 -sample-rate=41000 test2.png output.wav

# Generate a Scottie1 encoded image:
$ sstv-cli -s1 -sample-rate=41000 test2.png output.wav

# Display all modes:
$ sstv-cli -help
