Hello,
<BR>
<P>Glenn Ramsey and me wrote a scanning application for the Microtek 3600
<BR>
USB scanner. It is pure reverse engineering, since we got no information
<BR>
at all from Microtek until now. Thus the driver uses very much magic
<BR>
control values. But it works for at least Glenn and me. And if You test
<BR>
it with us, we can make it just better.
<BR>
<P>For now the tool can
<BR>
- safely return the scanner slider to home position
<BR>
- scan in RGB, gray, line mode and halftone (error diffusion)
<BR>
- scan in 75, 100, 200, 300, 600 DPI
<BR>
- produce PBM files (P4,P5,P6)
<BR>
- control brightness and contrast
<BR>
- scan an arbitrary window
<BR>
<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;See <A HREF="http://sm3600.sourceforge.net/">http://sm3600.sourceforge.net/</A>
<BR>
<P>There still is a lot to do, but well, we are on the verge to convert
<BR>
this application to a &quot;full&quot; SANE backend. I see no real problem with
<BR>
this. But...
<BR>
<P>I have no real vision, how to build a shared SANE backend module. The I
<BR>
can look up some source code aspects from the existing backends, and
<BR>
from the SANE API doc. This is quite fine.
<BR>
<P>The special SANE building process is not very clear for me, so I ask the
<BR>
humble question, if You have any hints for us, how to make it.
<BR>
<P>Our source consists of several modules (since the scanner is very dumb)
<BR>
and is normally linked against USBLIB. If it is possible, I would like
<BR>
to have it apart from the SANE distribution, until it gets more
<BR>
stabilised and (perhaps) de-modulized.
<BR>
<P>So we will apprechiate any information pointer for SANE integrations
<BR>
aspects, especially how to
<BR>
- link the backend as a SANE DLL module
<BR>
- install the additional backend by hand
<BR>
- address the usbfs root access issues in a sensible manner.
<BR>
<P>Please let me know, if You have any experiences handy, that can give us
<BR>
a jump start. There is a real chance, to get a working (alpha) driver
<BR>
for the sm3600 in the near future. Every contribution is apprechiated!
<BR>
<P>Mit freundlichen Gruessen / Yours sincerely
