<i>&gt;From: Bernd Schroeder &lt;<a href="mailto:Bernd.M.Schroeder@gmx.de">Bernd.M.Schroeder@gmx.de</a>&gt;</i><br>
<i>&gt;</i><br>
<i>&gt;&gt; The new os/2 compilation of SANE 1.0.1 gives me a core dump whenever I=20</i><br>
<i>&gt;&gt; try "36-bit Color" or "12-bit Gray" on my Microtek X6EL. My command=20</i><br>
<i>&gt;&gt; line is something like this:</i><br>
<i>&gt;&gt;=20</i><br>
<i>&gt;&gt; scanimage --device-name=3Dmicrotek2:b1t6l0 --mode=3D"36-bit Color"</i><br>
<i>&gt;&gt;trial.ppm</i><br>
<i>&gt;&gt;=20</i><br>
<i>&gt;&gt; Has anyone gotten either of these modes to work on a similar=20</i><br>
<i>&gt;&gt; configuration?</i><br>
<i>&gt;</i><br>
<i>&gt;1) With the version of the backend included in sane-1.0.1 the</i><br>
<i>&gt; scan mode option has been split into two options. You can</i><br>
<i>&gt; try instead something like this:</i><br>
<i>&gt;</i><br>
<i>&gt; scanimage --device-name=3Dmicrotek2:b1t6l0 --mode=3DColor --depth=3D8</i><br>
<i>&gt;</i><br>
<i>&gt; for a scan with 8 bit per color.</i><br>
<i>&gt;</i><br>
<i>&gt;2) Last time I checked scanimage didn=B4t support more than 8 bit</i><br>
<i>&gt; at all. In fact, if you issue a scanimage command and specify</i><br>
<i>&gt; a color depth of more than 8 bit scanimage tries to stop the</i><br>
<i>&gt; scan by sending a cancel command to the device. There seems</i><br>
<i>&gt; to be a bug in the backend, that it ignores a cancel during</i><br>
<i>&gt; a scan (but not during a preview).</i><br>
<i>&gt;</i><br>
<i>&gt;3) Of course, scanimage or the backend should not segfault, when</i><br>
<i>&gt; wrong parameters are specified. Actually this happens, when</i><br>
<i>&gt; scanimage reads the OPT_BR_X option, but I am not yet sure,</i><br>
<i>&gt; whether this happens, because the backend ignores the cancel</i><br>
<i>&gt; command. This happens on Linux, too, and is not a problem of</i><br>
<i>&gt; the OS/2 port.</i><br>
<i>&gt;</i><br>
<i>&gt;Bernd=20</i><br>
<i>&gt;</i><br>
<p>
<p>
<p>
That does explain my difficulties. Is scanimage the smallest available<br>
executable file that includes the back end?<br>
<p>
Incidentally, the new options do *not* seem to be recognized,<br>
and the split isn't yet menioned in the help.<br>
<p>
Thanks.<br>
<p>
