Hi Oliver...<br>
|
||
<p>
|
||
Many thanks for your reply.<br>
|
||
<p>
|
||
I'm glad that you also see a benefit from this interaction between<br>
|
||
SANE and TWAIN. The fact that TWAIN's user base is expressing<br>
|
||
an interest in UNIX is a little daunting in some ways, since not many<br>
|
||
of the current TWAIN members are doing anything with UNIX.<br>
|
||
So one of the opportunities we see from working with SANE is a<br>
|
||
chance to draw on your experience and expertise.<br>
|
||
<p>
|
||
As stated in my first message, I believe the principle benefit from<br>
|
||
SANE and TWAIN working together is a chance to help app<br>
|
||
writers cross from one OS to the other with less effort than it takes<br>
|
||
today. So, TWAIN runs on UNIX, SANE runs on Windows, and<br>
|
||
application writers have one less component to worry about<br>
|
||
when trying to build their source code on an alternate platform.<br>
|
||
<p>
|
||
Bearing that in mind, I propose that on UNIX TWAIN runs in<br>
|
||
communication with a generic Source that talks to SANE drivers.<br>
|
||
We would have to make some minor changes to our Source<br>
|
||
Manager to allow this to work properly, but such a TWAIN Source<br>
|
||
would be able to communicate with any SANE supported image<br>
|
||
capture device.<br>
|
||
<p>
|
||
At this time I don't believe there is much to be gained from having<br>
|
||
a generic SANE driver that talks to TWAIN. Technically it is very<br>
|
||
doable, but TWAIN Sources have a history of relying heavily or<br>
|
||
even exclusively on their internal GUIs, which doesn't fit well into<br>
|
||
SANE's programmatic design. We are working to change this<br>
|
||
behavior (and have been since TWAIN 1.7 -- 1997), so in the<br>
|
||
future it might be advantageous to do this.<br>
|
||
<p>
|
||
One question I have regarding SANE has to do with writing drivers<br>
|
||
for mulitple UNIX platforms. Writing a 'single' device driver for<br>
|
||
Solaris and AIX and Linux, etc must be appealing to some device<br>
|
||
manufacterers (nobody wants to have write one driver per OS for<br>
|
||
their device). Has SANE investigated an abstraction between<br>
|
||
it's interface and the actual communication with the OS? I'm kind of<br>
|
||
looking for something like ASPI (though wire independent). The<br>
|
||
idea being that me, as a driver writer, would be able to write a<br>
|
||
SANE driver that with a minimum of #ifdef's would be buildable on<br>
|
||
UNIX or Macintosh or Windows platforms.<br>
|
||
<p>
|
||
If such a mechanism could be created, I would have a very good<br>
|
||
reason for running SANE on Windows and Macintosh platforms...<br>

Hello,<br>
|
||
<p>
|
||
we are interested in the discussion about making available TWAIN<br>
|
||
on UNIX/linux and the coexistence of TWAIN and SANE on<br>
|
||
the same operating systems.<br>
|
||
I think there are a lot of thing both projects can benefit from.<br>
|
||
It also is interesting to see if it makes sense/is possible<br>
|
||
to make both standards work with each other<br>
|
||
(e.g. create a sane-backend that connects to TWAIN devices<br>
|
||
or to create a TWAIN device driver that makes available<br>
|
||
the devices supported by SANE, etc.).<br>
|
||
<p>
|
||
At first I have to take a closer look at the TWAIN standard to<br>
|
||
know what we are talking about.<br>
|
||
<p>
|
||
I will cc my mails to the sane-devel mailling list (so we can keep the<br>
|
||
discussion open for the people who are involved or interested in the<br>
|
||
sane development ). I will send the mails directly to you. If you like to<br>
|
||
I will also cc my mails to <a href="mailto:twain-wg@twain.org">twain-wg@twain.org</a>.<br>
|
||
<p>
|
||
Bye<br>
