G'day SANE developers,<br>
|
|
<p>
|
|
Firstly, congratulations on the fine work you folk have been doing as part of<br>
|
|
the SANE effort. It's certainly an impressive work, and a nice clean interface.<br>
|
|
May you all live long and prosper.<br>
|
|
<p>
|
|
Unfortunately I have a problem I was wondering if anyone could shed some light<br>
|
|
on. xscanimage hasn't been my friend today, and I'd like to make amends. The<br>
|
|
problem I'm having is that cancelling a scan doesn't work. My sane_cancel<br>
|
|
function gets called and xscanimage stops calling sane_read, but the "Scanning"<br>
|
|
panel with the progress bar never disappears. Attaching to xscanimage in<br>
|
|
gdb reveals that it's spinning around g_main_iterate chewing CPU time.<br>
|
|
Continuing to press the "Cancel" button on the "Scanning" panel causes<br>
|
|
sane_cancel to be called again, but my backend has well and truly stopped by<br>
|
|
this time, so it has no further effect.<br>
|
|
<p>
|
|
I tried upgrading libg and libgtk to 1.2.1, but with no improvement. Short of<br>
|
|
continuing to tear my remaining hair out or embarking on a multi-year course of<br>
|
|
study in the finer points of gtk, does anyone have any suggestions as to what<br>
|
|
might be causing this? I'm on a Red Hat 5.1 Linux system with sane 1.0.1-pre4.<br>
|
|
<p>
|
|
Thank you in advance,<br>
|
|
Graham<br>
