I recently tried Xsane 0.27 as an alternative frontend to<br>
xscanimage. Most of my current operations are negative scans<br>
from my HP Photosmart. From the way things operate I would<br>
guess Xsane loads a gamma map into the scanner based on the<br>
various preview settings. Does this map operate on the 10<br>
bit values that the Photosmart supposedly has internally?<br>
I have R032 of the scanner firmware which only returns 8<br>
bit values to the computer and I am noticing that some of<br>
my histograms are starting to get a little sparse.<br>
<p>
I have been trying to use the white-point pippette to<br>
remove the negative colour mask but there always seems<br>
to be residual colour. Could the pippette tools be altered<br>
to average a range of values? Being able to shift-click and<br>
drag to select a range of pixels to average would be optimal.<br>
<p>
Failing that, I have found the numeric value boxes on the<br>
gimp histogram tool to be ideal for entering colour<br>
correction values. A window giving the colour values for the<br>
white grey and black points would be a good alternative.<br>
<p>
Cheers,<br>
