Yes. It is intendend as it is normally used with the specific type of scanner.<br>
|
|
<p>
|
|
The SANE-coordinates are meant as correlated with the picture you want to<br>
|
|
scan. The hardware of most scanners will "suggest" an efficient way of<br>
|
|
doing it. I.e. the logical top-left of the picture you scan should be<br>
|
|
positioned in a way that it is in the same place on a "full-scan" regardless<br>
|
|
of how big the picture is.<br>
|
|
<p>
|
|
This normally means that the "top" should be oriented at the edge near the <br>
|
|
CCD-home-position and "left" should touch the corresponding border ...<br>
|
|
<p>
|
|
I.e. I would consider your scanner to be just a "turned round" version of<br>
|
|
the HP one (or one with the lid attached on the other side) and not try<br>
|
|
to "soft-emulate" another hardware-layout.<br>
