No - If I got the mail correctly, he is trying the other way round. That is<br>
|
|
making a TWAIN module (which can be called from TWAIN-aware frontends),<br>
|
|
that will call SANE (via network protocol ?) internally.<br>
|
|
<p>
|
|
That is, you could then access SANE data sources from Windoze TWAIN apps,<br>
|
|
but not vice versa.<br>
|
|
<p>
|
|
The other way round is IMHO at least _VERY_ hard, I actually think<br>
|
|
impossible to do. TWAIN includes the visual representation (what we call the<br>
|
|
frontend) in the driver, so we would need the full expected environment<br>
|
|
(i.e. Windows) available, and we still couldn't make SANE option descriptors<br>
|
|
from what the TWAIN driver does. I myself have sometimes big problems to find<br>
|
|
out what a particular button in one of those silly "cockpits" or whatever<br>
|
|
style the developer chose for the scanner dialog does what.<br>
|
|
<p>
|
|
But being able to scan remotely from windows would help me or rather those<br>
|
|
people here in the net, that don't understand Unix, a great deal (it<br>
|
|
would alleviate the need for a CGI script on my server). <br>
|
|
So the developers can be sure, that there are people out that that would be<br>
|
|
very grateful, when they make it.<br>
|
|
