<i>&gt; &gt; &gt; The images it scans are badly sheared.</i><br>
<i>&gt; &gt;</i><br>
<i>&gt; &gt; This was a problem with 0.7x because of the way that the number of</i><br>
<i>&gt; &gt; pixels/row was calculated - it didn't always match the data being</i><br>
<i>&gt; &gt; sent from the scanner. However, I haven't seen this problem in a</i><br>
<i>&gt; &gt; while. Are you sure you are using the most recent Umax backend?</i><br>
<i>&gt; &gt; Maybe you still have an old version around?</i><br>
<i>&gt; &gt;</i><br>
<i>&gt; </i><br>
<i>&gt; That problem never happend in the preview with any sane-version.</i><br>
<i>&gt; </i><br>
<i>&gt; The problem is still there, but I think it does not occur very often.</i><br>
<i>&gt; I asked UMAX how to handle this and the one I asked tries to find</i><br>
<i>&gt; out about that.</i><br>
<i>&gt; </i><br>
As a matter of fact, I have never had shear problems with either xsane<br>
or xscanimage. Instead, I have had shear problems myself when I first<br>
tried usin PIL's[*] sanemodule. FWIR, I solved the problem by changeing<br>
the end of scanline logic, since AMK thought any scanner would jump to<br>
the next line after 3*pixels were read. If you need it, ask me, and I'll<br>
send you my patched version of the file, since, as of now, Andrew has<br>
not still axcepted and merged my changes into his module.<br>
