Hi all,
A long time ago, there was a bug report submitted against sane 0.71-2
via the Debian BTS. It was a problem with custom gamma table which
causes undesired distortions :
| I have simply set the image intensity to about 1.5 and the red
| intensity to about 1.2. Whenever some very bright part of the
| picture is scanned, it is not read in as white but rather as some
| other color such as a light blue, yellow, green, or red. The white
| scanner background is almost a solid black. This phenomenon persists
| both in the prevue and the final scan.
The answer was :
| This problem is known:
| if you increase the size of the window in which the gamma-curve is
| displayed it could get better!
I have looked up in the changelog and in the source code, the mailing
list archives, and I haven't found any trace about a fix for this bug.
However, I failed to reproduce this bug on my computer.
Did anybody remember if this bug was fixed or not ?
Thanks for your help,
Aurelien Jarno
