Hi Rolf,
thank you for the patch. Now all resolutions up to 2400dpi give a
correct result.
At the moment I have no further observations to report.
If you want me to perform some extra tests, please let me know.
Cheers
Frank

Please report your results.
Many thanks for your help.

Hi all,
I recently bought a Canon MG7750. And I was rather badly surprised by
Canons own scanner driver for Linux.
Hence, first and foremost a big thank you to the SANE developers for
adding support for this model.
Since you asked for testers I made some scans with different settings.
All resolutions up to 600DPI work fine (http://susepaste.org/350ec6bf ).
1200DPI and 2400DPI work but the result looks rather strange
(=unusable) (http://susepaste.org/a7dbf6b8 and
http://susepaste.org/1ac92632 ).
All three files should show exactly the same picture.
For scanning only the resolution changed. No other setting was changed.
To reduce file size I compressed the images pretty strongly before
uploading. The 2400DPI scan is also reduced in resolution.
Hence, quality is well below the real scan quality.
But the problem is clearly visible.
SANE backends are from sane-backends-git20160322. OS is openSUSE
Leap42.1.
I hope this information helps. I will be happy to test newer versions
or tell you more information.
Cheers
Frank
