This sets an explict gamma correction for the image. If it is not |
| 30 |
|
|
specified, the default value of 2.0 is used. |

.TP |
| 32 |
|
|

.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 :-) |
