A different scale can be given with the |
| 46 |
|
.I \-s |
| 47 |
|
option. |
| 48 |
+ |
If the argument given to |
| 49 |
+ |
.I \-s |
| 50 |
+ |
begins with an "a" for "auto," then the maximum is used for scaling the result. |
| 51 |
|
The default multiplier is 179, which converts from radiance or irradiance |
| 52 |
|
to luminance or illuminance, respectively. |
| 53 |
|
A different multiplier can be given with |
| 90 |
|
.I \-n |
| 91 |
|
option can be used to change the number of contours (and corresponding |
| 92 |
|
legend entries) from the default value of 8. |
| 93 |
+ |
The |
| 94 |
+ |
.I \-lw |
| 95 |
+ |
and |
| 96 |
+ |
.I \-lh |
| 97 |
+ |
options may be used to change the legend dimensions from the default width |
| 98 |
+ |
and height of 100x200. |
| 99 |
+ |
A value of zero in either eliminates the legend in the output. |

The |

The |
