So I'm working on a project wherein I've removed the CCD and stepper motor from
the case, and have it mounted elsewhere.
I'm looking to get the image data from the scanner one scanline at a time
(rather than the entirety of all the scanlines at once), and I'm also looking
to make the scanner keep scanning until I signal it to stop (rather than
returning the carriage back it's starting point after 11 inches or whatever).
But I'm fairly pathetic in my programming skills. Are the backends capable of
doing these things?

Subject: [sane-devel] Canon MP450
Message-ID: <44214b15.4020...@iies.es>
Hi all!
I'd like to contribute to SANE by writing a back-end for my Canon Pixma
MP450 -well..., for all of them-. I've just started
sniffing the USB traffic, I've got some ideas and limited knowledge,
mainly about scanning protocols.
As you certainly know, the Canon MP450 is one of those multifunction
printers with scanner that can operate to some extent without
a PC. It can initiate the scanning process in several ways:
Scan and open the image with an application.
Scan and store the image in the PC in jpg.
in PDF.
Scan and send the image via e-mail.
My intention, as a first stage, would be to write a back-end that
receives the image scanned by the MP450 and decides which action
to perform over the image. I assume that the MP450 doesn't convert the
scanned image to, i.e., PDF. Is there any existing back-end with this
kind of behaviour?
I've seen that Christopher Albert is already working in a back-end for
the MP750. Maybe both printers use the same protocol and should be
supported
by the same back-end. I've already asked him to translate his notes to
English.
Any help would be appreciated!!
Kind regards.
