If this works already, I'm not sure what you want changed in SANE ?<br>

Mmm. Well, the nice thing about the HP design is that I can write something<br>
|
|||
|
|
to do this, totally automatically, and without behaviour I don't know<br>
|
|||
|
|
about behind the scenes. I'd like this preserved, but it's fine if this<br>
|
|||
|
|
works just when source == MANUAL or whatever.<br>
|
|||
|
|
<p>
|
|||
|
|
while (we've got some sheets left) {<br>
|
|||
|
|
load another sheet<br>
|
|||
|
|
quick-preview-scan<br>
|
|||
|
|
auto-select scan area (just call lists) and brightness/ contrast<br>
|
|||
|
|
high-resolution-scan > file<br>
|
|||
|
|
}<br>

Does this mean that the UMAX can really load and unload pages, but you<br>
|
|||
|
|
choose not to export this behaviour from the backend?<br>
|
|||
|
|
<p>
|
|||
|
|
Can I do this (below) with the design you have in mind?<br>
|
|||
|
|
<p>
|
|||
|
|
1. Put phone bill (35 sheets) into hopper, run Xsane<br>
|
|||
|
|
2. Scan in first sheet, hand-tune brightness and scan area in Preview<br>
|
|||
|
|
3. Do a final scan on that first sheet, check it for problems<br>
|
|||
|
|
4. Tell Xsane "Scan all the remaining sheets with those settings"<br>
|
|||
|
|
5. Go and have coffee<br>
|
|||
|
|
<p>
|
|||
|
|
ALSO: Can I do this *without* XSane, in a shell script or OCR program?<br>
|
|||
|
|
<p>
|
|||
|
|
Nick.<br>
