So this ends up being a frontend problem, not a backend problem... using<br>
|
||
xsane (0.37) rather than xscanimage (1.0.1) fixes the problem...<br>
|
||
<p>
|
||
Compiling xsane 1.0.1 with just "-g" instead of "-g -O2" may fix my gamma<br>
|
||
problem there... does xsane use different gamma transform code?<br>
