I have some sample USB traces of this scanner. I don't recall at this moment what the image format was- I'll have to look at it some this weekend. allan On Fri, Jan 30, 2015 at 2:59 PM, Glenn Serre wrote: > Good morning, > > I have a Canon DR-C225 that I'd like to use on my Ubuntu box. I think

[sane-devel] Support for Canon DR-C225?

Good morning, I have a Canon DR-C225 that I'd like to use on my Ubuntu box. I think that it is not currently supported because: scanimage -L No scanners were identified. [...] even though sane-find-scanner reports: [...] found USB scanner (vendor=0x1083, product=0x1658) at libusb:004:011 [...]

"they all do that" is specific to these HP all-in-ones. Other scanners fix this in hardware or in the driver software. Does their TWAIN driver do this on windows? Not everyone uses xsane- what about scanimage or gscan2pdf. They would also have to implement this flipping code. Hence, this is a prob

Thanks, Allan. I talked with HP tech support about this too and the answer I got was, "they all do that" and, if you want that kind of scanning (where all the pages come out right-side-up), you have to get a dedicated scanner which costs twice as much (and doesn't have printing and faxing capa

I hate to sound like a broken record :) I don't think there is a setting to fix this in xsane, because this is a bug in the backend. IMHO, the individual backend is responsible for making the image make sense. In the short term, you should be able to use 'convert -rotate 180' to rotate those image

[sane-devel] correcting upside-down pages in duplex mode using ADF

When scanning several pages using the ADF in duplex mode, the backside of each page is rendered upside-down. Is there some setting in xsane to flip the backside of each page vertically so that it's right-side-up? Failing that, is there a utility to accomplish the same thing programmatically a

The apps I've been using to examine the scans I've made so far are ImageMagick's "display" and "gimp" Both of these-- which I've used countless times over many years-- always worked fine in the past. But for some reason, the images scanned at 1200 dpi looked horrible when displayed by either of
