Hello,
|
|
|
|
I have, for personal reasons, had to invest some time into getting SANE
|
|
network scanning to work for Windows clients.
|
|
WinSane would not work for me, it crashed every time.
|
|
|
|
I attach the result, which is a TWAIN data source that can access SANE
|
|
backends. Unlike WinSane, this one is open source!
|
|
It works quite well on my SnapScan e20, other's mileage may vary. It's all
|
|
in German, too, but there isn't much text, so translation should be easy.
|
|
I would encourage anyone willing to do some work on it, to make it into the
|
|
universal tool it could be. I don't have time to do further development on
|
|
it.
|
|
|
|
Now, here's the legal bit:
|
|
The code included is in part written by others:
|
|
The TWAIN driver skeleton is from the Twain Working Group, and copyrights
|
|
may apply.
|
|
Some of the image manipulation is from liblug, which is included as part of
|
|
the source tree. It is open source, requiring only the copyright to be
|
|
present in the source code.
|
|
Part, of course, is SANE stuff itself.
|
|
It uses the scanimg.exe binary from WinSane, so that needs to be present.
|
|
All other code is mine, and can be copied, developed and deployed as anyone
|
|
may see fit. I would however like to have it evolve into a standard frontend
|
|
for Windows scanning via SANE.
|
|
|
|
Features are: Preview scan, zoom preview, selection of resolution and color
|
|
depth, image adjustments (gamma, brightness, sharpen, blur) and transfer via
|
|
file, memory and Windows native mode.
|
|
This is by no means clean code, much is redundant, useless or inefficient.
|
|
Be welcome to make any changes to improve it.
|
|
In scanner.c, the SANE backend is hardcoded. That would need to be changed
|
|
first, I'd guess.
|
|
Gray scaled bitmaps are transferred to the application as RGB. This is
|
|
needed because Corel Photo Paint and CorelDraw will not work when paletted
|
|
images are transferred, God only knows why.
|
|
Because of that, there is a lot of hard to understand code in scanner.c, but
|
|
that part is working perfectly, so it may be good to leave that alone at
|
|
first.
|
|
B/W scanning may need to take the PIXELFLAVOR setting into account,
|
|
currently is does not.
|
|
|
|
To get it to build, you will need:
|
|
MSVC 6.0 Professional Edition
|
|
WinSane (for scanimg.exe and sanedll.dll)
|
|
The Twain Working Group driver skeleton (maybe)
|
|
|
|
If you cannot compile without the Driver toolkit from Twain Working Group,
|
|
you will need to unzip the attached file in such a way that the "SANE
|
|
Driver" directory becomes a sibling of the Twain Working Group's driver
|
|
toolkit. Then, compile the toolkit version of the driver and delete the .ds
|
|
file from the c:windows\Twain_32\Sample directory.
|
|
|
|
When compiling, a directory c:\twain will be created. There you will find
|
|
the data source (.ds) file. Place that in c:\windows\twain_32, along with
|
|
scanimg.exe and sanedll.dll.
|
|
|
|
That should be all that's needed.
|
|
|
|
I'm sorry I can't make this any easier, but I'm not an expert at Windows
|
|
application packaging. Maybe someone else can make a nicer package from it.
|
|
|
|
Best regards,
|
|
|
|
Mike
