Re: [sane-devel] Please: CanoScan Lide 220

If you could provide the exact versions of sane-backends and sane-frontends you are using, that would be more useful. I have a Canon CanoScan LiDE 220 sitting right next to me and it is functioning quite well (I'm using scanimage to drive it). Try running $ scanimage -d genesys --format=tiff

Re: [sane-devel] [PATCH v3] Swap bytes in 16-bit PNGs, because PNG is big-endian.

Sorry about the volume, third time is definitely the charm. Admittedly I struggled to grasp the style rules. I noticed the PNG byte order issue fixed by this patch when using genesys with a CanoScan LiDE 220. I do not have any other supported scanners close at hand, so I hope somebody can confirm

Pleased to make your acquaintance, Olaf. Thank you for reviewing the patches and taking them upstream, I have an equivalent patch for JPEG output on the boil. Not to put you on the spot, but it seems like a lot of time has passed since the last release was tagged, despite there apparently being

Re: [sane-devel] [PATCH 3/3] Avoid attaching grayscale ICC profiles to rgb images, or vice-versa.

I just tried it by hacking scanimage up a bit to threshhold and convert the lines to monochrome right before writing the PNG, and change the PNG header to always be 1-bit; libpng didn't complain about attaching a grayscale profile to a 1-bit monochrome image. -- sane-devel mailing list:

Re: [sane-devel] CanoScan LiDE 220 can't scan dpi over 1200

Hmm, can confirm, it scans some portion of the image and then hangs. I think the official software on Windows doesn't support full-page scans at 2400dpi or greater. It does work if you limit the scan to an area. Not sure what should be done about this, I don't think there's a standard way to
