<P><P>Hi Michael,
|
|
<BR>
|
|
<P>you are right.
|
|
<BR>
|
|
I did take a look at xsane.
|
|
<BR>
|
|
At first xsane can expect that the data depth is correct in
|
|
<BR>
|
|
the parameter struct because there is no reason at all why
|
|
<BR>
|
|
the backend does not now the bit depth before sane_start is
|
|
<BR>
|
|
called and so the backend has to set the correct value when
|
|
<BR>
|
|
it works conform to the SANE standard.
|
|
<BR>
|
|
<P>Although it is not nice that xsane produces a segfault it
|
|
<BR>
|
|
makes sense to create the gamma table before sane_start is
|
|
<BR>
|
|
called. The creation of the gamma tables can take some time
|
|
<BR>
|
|
and it is not good to interrupt the scanning for this
|
|
<BR>
|
|
what can happen on slow computers.
|
|
<BR>
|
|
<P>I will add a bugfix (some day).
|
|
<BR>
|
|
<P>Bye
|
|
<BR>
|
|
