The exposure value may either be given as a positive real value, or | 
| 493 | 
< | 
as a real value preceeded by a '+' or '-' indicating a positive or | 
| 493 | 
> | 
as a real value preceded by a '+' or '-' indicating a positive or |

  | 
negative number of f-stops (powers of two) from the original value. |

If no exposure is given, pfilt will automatically compute the |

  | 
the positive Y axis (+Y), the positive Z axis (+Z), the negative | 
| 708 | 
  | 
X axis (-X), the negative Y axis (-Y), or the negative Z axis (-Z). |

The "Delete" button on the Results screen is used to remove the |

  | 
selected picture files from the filesystem. |

Associated raw picture and z-buffer files |

will also be deleted if they exist. |

The print command window on the Results screen contains the system | 
| 1360 | 
  | 
command to use in printing out finished Radiance pictures. | 
| 1361 | 
  | 
The "%s" format field, which must appear somewhere in the command, | 
| 1362 | 
< | 
is replaced by the selected Radiance picture file name(s). | 
| 1362 | 
> | 
is replaced by the selected Radiance picture file name. | 
| 1363 | 
> | 
This command is executed multiple times if multiple files are | 
| 1364 | 
> | 
selected. | 
| 1365 | 
  | 
 | 
| 1366 | 
  | 
The default command is "ra_ps %s | lpr", which converts the Radiance | 
| 1367 | 
  | 
picture to a black and white PostScript file and sends it to the lpr | 
| 1368 | 
  | 
print spooler. | 
| 1369 | 
+ | 
Add a "-c" option to "ra_ps" if the printer supports color. | 
| 1370 | 
  | 
If your printer does not understand PostScript, or your system does | 
| 1371 | 
  | 
not support lpr, this command must obviously be changed. |
