[sane-devel] gscan2pdf v1.2.4 released
gscan2pdf - A GUI to produce a multipage PDF or DjVu from a scan. http://gscan2pdf.sourceforge.net/ Only two clicks are required to scan several pages and then save all or a selection as a PDF or DjVu file, including metadata if required. gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via libsane-perl, scanimage or scanadf, and can scan multiple pages at once. It presents a thumbnail view of scanned pages, and permits simple operations such as cropping, rotating and deleting pages. OCR can be used to recognise text in the scans, and the output embedded in the PDF or DjVu. PDF conversion is done by PDF::API2. The resulting document may be saved as a PDF, DjVu, multipage TIFF file, or single page image file. Changelog for 1.2.4: * Tie PageRange widgets together Closes bug #165 "all or selected? a surprise that can bite like snake" again * Fix parsing the units of the resolution of imported images. * Fix infinite loop scanning page 1 when 5+ exist. * Parse negative progress percentages from scanimage. * Fix scan dialog if no devices found. -- next part -- A non-text attachment was scrubbed...

What is the problem with waking from sleep for these scanners? Where to start looking to fix this problem?
[sane-devel] Canon P-215 USB modeswitching
Hi Allan! On 04/03/2014 03:03 AM, m. allan noah wrote: > I worked on the backend for this scanner remotely, but I've never > actually touched one. I had no idea it did this modeswitching. Short update: After unsuccessfully trying several hours to get the proprietary Canon backend compile with SANE, I did some more tests with the backend you wrote and it turns out that I just had to flip the switch on the backside of the scanner labeled "Auto Start" (see [1], p. 13). Setting that switch to "Off" will turn the scanner immediately into scan mode, changing its USB device ID to 0x1646 and making it work like a charm with your backend. I could scan both simplex and duplex, b/w and color and use all possible resolutions, very happy with the scanner now :). It should probably added to the manpage of the canon_dr backend that this switch needs to be turned off.

[sane-devel] Header files required to build backends
Hello! While trying to get the Canon P-215 document scanner work with SANE, I stumbled across a driver package directly offered by Canon [1]. This driver packages contains two 32 bit packages for both .rpm- and .deb-based systems, no 64 bit packages, but at least a source tarball with a binary blob and some C code. Since my host system is running a 64 bit unstable, I thought I'd try rebuilding the package for 64 bit. While doing that, I found that the libsane-dev package in Debian currently contains solely two header files, namely "sane.h" and "saneopts.h" while the SANE upstream sources contain many more headers files from which the Canon driver also needs several of. Can anyone agree that the libsane-dev package in Debian should ship all header files such that external backends can be developed? If yes, I'd help Mark Buda, the current maintainer of the package in Debian, to get a fixed version of the package into unstable.

Yes, I saw you were the author of the backend, so I was hoping you'd be chiming in to reply :). I still have this particular scanner here and there is even a driver supplied by Canon in source which includes a binary blob, however, so I'm not sure whether you can find the proper control sequence in the sources. I have already skimmed through the source code and found nothing so far. Do you have any idea what we could do to find the proper command to set the scanner into scanner mode? Would a USB dump on Windows help? Adrian -- .''`.

Those interfaces are not stable and not considered part of the 'interface' of sane. In my opinion, backends that use them but include closed source components are skirting the edges of their legal rights, by denying you yours. allan -- "The truth is an offense, but not a sin"
[sane-devel] Canon Image Formula dR 9050c
I had a long email thread with Philip Gwyn who did the initial development work. He was unable to make the machine wake up from software, but did not continue to try, because adding paper to the input hopper will wake it up. If you wanted to debug further, we could try to get logs of the scanner when it demonstrates this behavior, using sane-backends git development version. There have been some updates to the canon_dr backend recently that might help. allan On Thu, Apr 3, 2014 at 7:30 AM, Gjermund Gusland Thorsen wrote: > What is the problem with waking from sleep for these scanners? > Where to start looking to fix this problem? > > -- > sane-devel mailing list: sane-devel at lists.alioth.debian.org > http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel > Unsubscribe: Send mail with subject "unsubscribe your_password" > to sane-devel-request at lists.alioth.debian.org -- "The truth is an offense, but not a sin"
