The number of components indicates that each matrix element is actually |

Radiance spectral pictures with more than 3 components are also supported. |

These are typically produced by |

.I rtrace(1) |

or |

.I rfluxmtx(1). |

as ASCII (-fa), binary doubles (-fd), floats (-ff), or RGBE colors (-fc). |

In the latter case, the actual matrix dimensions are written in the resolution |

string rather than the header. |

In the one-component case, the output is written as grayscale. |

If more than 3 components are in the final matrix and |

.I -fc |

is specified, the output will be a Radiance spectral picture. |
