Gack! How do I submit a bug report? Would it be worth anyone's while for me<br>
|
|
to look though the code myself... I'm thinking that this would not be an<br>
|
|
obvious bug or it would have bitten other Mustek users before now. <br>
|
|
<p>
|

Ah. That's useful to know. I've long since lost any manuals that came with<br>
|
|
the Mustek, so I wasn't sure what it could do. I did remember that it was<br>
|
|
better than the Plustek it replaced, which was capable of up to 300dpi. In<br>
|
|
the Windoze dialogue that comes up it shows resolutions up to 1200 dpi, then<br>
|
|
a separator, and then 2400 and 4800. That's what my assumptions were based<br>
|
|
on (although it did seem a little to good to be true!).<br>
|
|
<p>
|
|

<p>
|

But possibly the error is in how xscanimage calls the API (or scanimage),<br>
|
|
not in the driver or scanimage itself?<br>
|
|
<p>
|
|

I did try that but all I got was<br>
|
|
<p>
|
|
Usage: scanimage [OPTION]...<br>
|
|
<p>
|
|
Start image acquisition on a scanner device and write PNM image data to<br>
|
|
standard output.<br>
|
|
<p>
|
|
-d, --device-name=DEVICE use a given scanner device<br>
|
|
-h, --help display this help message and exit<br>
|
|
-L, --list-devices show available scanner devices<br>
|
|
-T, --test test backend thoroughly<br>
|
|
-v, --verbose give even more status messages<br>
|
|
-V, --version print version information<br>
|
|
<p>
|
|
<p>
|
|
<i>> Eventually -L might be useful to list the found devices and -d to </i><br>

|
|
Hmm.. maybe I misunderstood. Perhaps I should have used "scanimage -h<br>
|
|
--device-name=mustek" (i forget at the moment the device convention, but..)<br>
|
|
instead of just "scanimage -h" to get device specifc help?<br>
|
|
<p>
|
|
<p>
|
|
<i>> Try the options --resolution, -x and -y (width and height, it will</i><br>

|

<p>
|
|
Thanks! Do you know offhand where/if these option are documented? I searched<br>
|
|
and grepped to no avail!<br>
|
|
<p>
|
|
<p>
|
|
Anyone else Out There using a Mustek 6000CX with SANE and getting >300dpi?<br>
|
|
<p>
