I have the scanner Canon LIDE 210 and recognized that scanning in 600dpi gray results in an image which is wrong. The content in Y-direction is not complete. It looks like first cropped and then stretched to the max y-length of about ~7000 px. Scanning in 600dpi colour works. So I wondered and started a Knoppix 7.4.2 and tried the 600dpi-gray-scan. Result was good. The difference seems to be the version of sane-backends: - 600-dpi-gray-good-Knoppix-7.4.2: the package-dvd.txt shows version 1.0.22 of some libsane packages - 600-dpi-gray-bad-gentoo-actual: media-gfx/sane-backends-1.0.24-r5 is installed To verify it, I installed manually with my portage-overlay media-gfx/sane-backends-1.0.22::Mario from the sources without any patch. (https://alioth.debian.org/frs/download.php/file/3503/sane-backends-1.0.22.tar.gz). 600-dpi-gray-scan works now again. Reproducible: Always Steps to Reproduce: 1. use media-gfx/sane-backends-1.0.24-r5 2. scanimage --format=tiff --resolution 600 > test001.tiff 3. look at the image (no matter if tiff or png) Actual Results: Image looks like first cropped and then stretched. So it is not complete and aspect ratio is wrong. Expected Results: scanned image should look like the original. I will add a screenshot where you see the difference between media-gfx/sane-backends-1.0.22 and media-gfx/sane-backends-1.0.24-r5 (scan_600gray_1.0.22_and_1.0.24.png). # sane-find-scanner -q found USB scanner (vendor=0x04a9 [Canon], product=0x190a [CanoScan]) at libusb:003:006 # scanimage -L device `genesys:libusb:003:006' is a Canon LiDE 210 flatbed scanner

Created attachment 403260 [details] scan_600colour_1.0.24 When using 600dpi and color (instead of gray), it works with sane-backends-1.0.24-r5.

Please retry with sane-backends 1.0.25_pre* snapshot
I retried with media-gfx/sane-backends-1.0.25_pre20150628::gentoo USE="ipv6 threads usb" and the problem still exists. 600dpi gray results in an incomplete scan 600dpi color results in a correct scan.
Created attachment 406428 [details] Example The 600dpi gray scan is still incomplete and wrong. Please fix it. There must be a wrong calculation in the source code.
Then, please, report it to upstream as, otherwise, I doubt it will be ever fixed here downstream :( Thanks -> http://www.sane-project.org/bugs.html

Created attachment 408970 [details] sane-backends-1.0.23.ebuild
please try the 1.0.22 and 1.0.23 ebuilds and see if either works. that'll help narrow down things (assuming one does).
SpanKY, sane-backends-1.0.22 is the last version without problems. Your ebuilds are not able to fetch the sources. Is there a difference between manually installed version 1.0.22 and your ebuild-version-1.0.22? I am not able to report upstream because I am not able to create an account at sane-project / alioth.debian.org. @sane-project I thought the scanner canon lide 210 were very popular. Why could such a bad bug be introduced in the source code? Is somebody testing the builds after changing source code?
(In reply to Mario Bachmann from comment #11) fetches fine for me, but you didn't post any logs, so i don't know why it's failing for you $ wget https://alioth.debian.org/frs/download.php/file/3752/sane-backends-1.0.23.tar.gz.1 --2015-08-20 05:17:15-- https://alioth.debian.org/frs/download.php/file/3752/sane-backends-1.0.23.tar.gz.1 Resolving alioth.debian.org (alioth.debian.org)... 5.153.231.21 Connecting to alioth.debian.org (alioth.debian.org)|5.153.231.21|:443... connected.

thanks, that helps narrow down the issue between 1.0.23 and 1.0.24, which is still like 373 commits in upstream. there are a few suspicious ones for that driver that might be worth checking out. i've added a 9999 ebuild to the tree that you can use to try and bisect. set EGIT_COMMIT before emerging it to try older versions. something like: $ EGIT_COMMIT='RELEASE_1_0_24~150' emerge ~sane-backends-9999 you'll want to use diff values to narrow down the bad commit: EGIT_COMMIT='RELEASE_1_0_24' EGIT_COMMIT='RELEASE_1_0_24~100' EGIT_COMMIT='RELEASE_1_0_24~200' EGIT_COMMIT='RELEASE_1_0_24~300' don't go above 400 though as that goes past the 1.0.23 version. you should be able to manually bisect down the numbers i think.
Where do I find sane-backends-9999? Do I need to add an overlay? I did an "emerge --sync" and I only see sane-backends-1.0.24-r5.ebuild sane-backends-1.0.25_pre20150628.ebuild in the folder /usr/portage/media-gfx/sane-backends/
(In reply to Mario Bachmann from comment #17) i just committed it, and rsync mirrors don't update instantly, so you'll have to wait a bit
After a lot compiling I found the introduction of the bug. Last version which works perfect: EGIT_COMMIT='RELEASE_1_0_24~55' emerge -v ~sane-backends-9999 Image [gray/600dpi] is correct. First version with the problem: EGIT_COMMIT='RELEASE_1_0_24~54' emerge -v ~sane-backends-9999 Image [gray/600dpi] is incomplete (cropped and stretched).
i've filed a bug upstream now, but really you'll need to follow up if they have questions. i'm not going to play telephone here.
