.BI -pc " xr yr xg yg xb yb xw yw" |
| 275 |
+ |
Use the specified chromaticity pairs for output primaries and white |
| 276 |

point rather than the standard RGB color space. |
| 277 |

.TP |
| 278 |

.BR \-pRGB |
| 279 |

Output standard RGB values (the default). |

.TP |

.BR \-pXYZ |
| 282 |

Output standard CIE XYZ tristimulus values rather than RGB. |

.BI -f \ source |
| 285 |

Load definitions from |

and assign at global level. |

.TP |

.BI -dj \ frac |
| 294 |
|
Set the direct jittering to |
| 295 |

.I frac. |

divided by the given |

|
.I frac. |

.BI -cs \ Ns |
| 722 |

Use |
| 723 |
+ |
.I Ns |
| 724 |
+ |
bands for spectral sampling rather than the default RGB calculation space. |
| 725 |
+ |
The maximum setting is controlled by the compiler macro MAXCSAMP, and |
| 726 |

defaults to 24. |
| 727 |

Larger values for Ns will be reduced to MAXCSAMP. |

.TP |

.BI -cw " nmA nmB" |
| 730 |
+ |
Set extrema to the given wavelengths for spectral sampling. |
| 731 |

The default is 380 and 780 nanometers. |
| 732 |

.BI -S \ seqstart |

Instead of generating a single picture based only on the view |

Send error messages and progress reports to |
| 926 |
