Rolf:
I see now how to specify resolution in the command $ scanimage.
Also, if I select a preset area of 15 cm x 10 cm for Acquire
preview,
and I have positioned the photo in Landscape orientation, the preview
image is in Landscape as expected. It is just in selecting 4 in x 6
in that
there is a problem with the image being cut off. It would be nice to
have
preset choices of 4 in x 6 in and 6 in x 4 in.
Kind regards,
Bill

I added your repository and files and after got this:

device `canon_pixma:libusb:001:006' is a CANON TS6200 series flatbed
scanner
With my usb connection, all of the issues that I had listed in
my
original post
(https://alioth-lists.debian.net/pipermail/sane-devel/2019-March/036608.html)
have been resolved, except that, for Xsane/Advance Options, pressing
“Update button state” has no affect and the other 5
sliders/windows are
grayed out; however, I haven’t explored the “button” thing
yet. After
configuring Xsane/Setup optimally for the photos that I was
scanning,
the scanned images look great at all resolutions thru 1200 ppi.
After testing scanimage, simple scan, and xsane I have the
following observations and questions:
For scanimage scan: Results from this scan of a 4” x 6”
(152.4mm x
101.6mm) photo has a resolution of 75 ppi. Is there a way to get
higher
resolutions with this command? I didn’t see any here:
http://manpages.ubuntu.com/manpages/bionic/man1/scanimage.1.html
For simple scan: With 4” x 6” photo oriented Landscape at upper
right
corner of the platen, the scanned image is cut off on the right
side,
showing a 4” x 4” Landscape image in the upper portion of a 4”
x 6”
Portrait frame. If I position the photo oriented Portrait at the
upper
right corner of the platen, the scanned image fills the 4” x 6”
Portrait
frame, which can then be rotated 90* and saved in the Landscape
orientation. Not sure if this was intended, or not.
For Xsane scan: With the 4” x 6” photo oriented Landscape, and
a “full
size” “Acquire preview” done, the 4” x 6” image is shown
Landscape at
the upper left as expected. But if, instead of “full size”, I
select
4” x 6”, the “Acquire preview” is a 4” x 4” Landscape
image, with the
right side cut off. Re-orienting the photo as above for simple scan
has
the same outcome. Again, not sure if this was intended, or not.
Lastly, what is the difference between the setting in Xsane
Setup/Copy/Scan Resolution and Xsane Main menu/Set scan resolution?
Does the Main menu supersede the Setup settings?
How do I delete “device `canon_pixma:libusb:001:006' is a CANON
TS6200
series flatbed scanner”?
Should I proceed with the WiFi setup?
Thanks for the quick response and excellent fix!
Kind regards,
Bill

Hi,
Yesterday I merged the merge request bachends/!43. You can update
SANE
from my Ubuntu ppa
(https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git) later
today.
Please report if the scanner is working with SANE, especially scans
600dpi.
Before you start with WiFi connection, please test USB first.
Hope this helps.
Cheers,
Rolf

I find it unfortunate that the backend pixma does not take input
usb-id.
The pixma driver supports all printer scanners:
canon pixma ts and canon pixma mg.
Currently you have to add it directly in the code.
I assume that the pixma backend maintainer would welcome a patch
adding
support for this ;-)
Hope this helps,
