This backend dynamically enabeles the options that are supported
|
|
by the scanner in dependence of the scanning-mode and other options. Here
|
|
is an example of the frontend
|
|
<a href="http://www.xsane.org">XSane</a>:

|
|
|
|
<p><br>
|
|
The options Gamma, brightness, contrast and negative in the
|
|
main window come from xsane that calculates a gamma table using this values.
|
|
These values are corelated to highlight, midlight and shadow sliders in
|
|
the Histogram window.

bit depth (otherwise xsane does the conversion with the selected output
