|
.TP 10n |
| 28 |
|
|
.BI \-g " gamma" |
| 29 |
|
|
This sets an explict gamma correction for the image. If it is not |
| 30 |
|
|
specified, the default value of 2.0 is used. |
| 31 |
|
|
.TP |
| 32 |
|
|
.B \-v |
| 33 |
|

|
|
.TP |

.BI "\-e +/\-" " stops" |
| 37 |
|

.SH BUGS |
| 60 |
|
|
Does not yet do Macintosh PICT to Radiance PIC, as this PICT files |
| 61 |
|
|
are a lot more complex than just one bit map. This is left as an |
| 62 |
|
|
exercise for the reader :-) |
