.TP |

.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). |
| 280 |
+ |
.TP |
| 281 |
+ |
.BR \-pXYZ |
| 282 |
+ |
Output standard CIE XYZ tristimulus values rather than RGB. |

.BI -f \ source |
| 285 |
+ |
Load definitions from the file |
| 286 |
+ |
.I source |
| 287 |
+ |
and assign at the global level. |
| 288 |
+ |
The usual set of library directories is searched based on the |
| 289 |
+ |
.I RAYPATH |
| 290 |
+ |
environment variable. |
| 291 |
+ |
.TP |
| 292 |

.BI -e \ expr |
| 293 |

Set additional definitions from |
| 294 |
+ |
.I expr. |

.TP |

|
.BI -dj \ frac |
| 297 |
|
Set the direct jittering to |
| 298 |
|
.I frac. |
| 721 |
|
divided by the given |
| 722 |
|
.I frac. |
| 723 |

.TP |
| 724 |
+ |
.BI -cs \ Ns |
| 725 |
+ |
Use |
| 726 |
+ |
.I Ns |
| 727 |
+ |
bands for spectral sampling rather than the default RGB calculation space. |
| 728 |
+ |
The maximum setting is controlled by the compiler macro MAXCSAMP, and |
| 729 |
+ |
defaults to 24. |
| 730 |
+ |
Larger values for Ns will be reduced to MAXCSAMP. |
| 731 |
+ |
.TP |
| 732 |
+ |
.BI -cw " nmA nmB" |
| 733 |
+ |
Set extrema to the given wavelengths for spectral sampling. |
| 734 |
+ |
The default is 380 and 780 nanometers. |
| 735 |
+ |
The order specified does not matter. |

.BI -S \ seqstart |
| 738 |
|
Instead of generating a single picture based only on the view |
| 739 |
|
parameters given on the command line, this option causes |
| 928 |
|
Send error messages and progress reports to |
| 929 |
|
.I efile |
| 930 |
|
instead of the standard error. |
| 931 |

(Note this option overlaps with "-e expr" above, so file paths |
| 932 |

with '=' or ':' in them are not allowed on this option.) |

.BR \-w |

Boolean switch for warning messages. |
