<i>&gt; Yes. That's what I'm asking for. But it needs someone with good knowledge</i><br>
<i>&gt; about the TWAIN API. I volunteer to help that person with all questions of</i><br>
<i>&gt; SANE interfacing. To do it "right", we will need to define a "remote</i><br>

<i>&gt; the TWAIN layer to interface with an arbitrary SANE frontend.</i><br>
<p>
I am interested in adding a TWAIN-driver-level-interface to xsane.<br>
<p>
<p>
<i>&gt; For having TWAIN style access to scanners on Unix (thus allowing application</i><br>
<i>&gt; programmers to port their programs more easily), we'd need the</i><br>
<i>&gt; abovementioned "remote control" for SANE frontends.</i><br>
<i>&gt;</i><br>
<p>
We should define a standard for the communication<br>
between the TWAIN to SANE-FRONTEND wrapper<br>
and sane frontends.<br>
<p>
-- TWAIN-application layer<br>
-&gt; TWAIN-source-selection-layer<br>
-&gt; TWAIN to  SANE-FRONTEND-wrapper<br>
-&gt; SANE-FRONTEND<br>
-&gt; ...<br>
<p>
The wrapper and the standard has to be compatible to<br>
all operating systems.<br>
<p>
